As the successor to the Leica SL2-S, this new model incorporates advancements, particularly in its autofocus and video recording capabilities, reflecting Leica’s commitment to evolving its mirrorless offerings.

Leica’s decision to release the SL3-S as a lower-resolution variant alongside the higher-resolution SL3 echoes a pattern observed in their previous product cycles, such as the SL2 and SL2-S. This suggests a deliberate market segmentation strategy, where the SL3 addresses users’ needs requiring maximum image detail. At the same time, the SL3-S focuses on optimising speed and video performance to appeal to a different segment of the professional market. Despite its positioning against “mainstream brands”, the Leica SL3-S commands a premium price, indicating that Leica is targeting a specific niche of users who value factors beyond mere technical specifications. This suggests that elements such as brand prestige, build quality, the unique Leica user experience, or specific feature implementations are key differentiators for their target demographic.

2. Technical Specifications and Key Features:

The Leica SL3-S is built around a 24.6-megapixel effective resolution full-frame Back-Side Illuminated (BSI) CMOS sensor. This sensor is coupled with the new Maestro IV processor, which incorporates L2 technology, enabling high-speed data processing and contributing to the camera’s overall performance. The camera boasts a wide ISO range, extending from ISO 50 to 200,000, providing considerable flexibility in various lighting conditions. The choice of a 24MP sensor, a resolution frequently favoured in high-performance cameras, indicates a strategic focus on achieving a balance between detailed image capture and efficient performance in speed and low-light sensitivity. The Maestro IV processor integration, also found in recent high-end Leica models like the SL3 and Q3, points to a consistent image processing pipeline across Leica’s premium offerings. This likely ensures a familiar and reliable image rendering and overall system responsiveness for users within the Leica ecosystem.

A significant advancement in the Leica SL3-S is its autofocus system. It now employs a hybrid approach combining Phase Detection Autofocus (PDAF) with 779 distinct focus points, depth map technology for object detection, and traditional contrast detection. This sophisticated system also incorporates subject recognition capabilities, allowing it to identify and track people (including head, face, and eyes) and animals. The camera can continuously shoot up to 30 frames per second at impressive speeds when capturing 12-bit RAW images with continuous autofocus engagement. Including PDAF marks a notable upgrade from earlier Leica SL models, which primarily relied on contrast detection for autofocus. PDAF generally offers faster and more effective focusing, particularly when tracking moving subjects, thus enhancing the camera’s ability to capture dynamic scenes. The synergy of three distinct autofocus technologies suggests a robust and adaptable system to deliver reliable performance across various shooting conditions.

The Leica SL3-S incorporates a 5-axis in-body image stabilisation (IBIS) system to mitigate camera shake. This system is rated to provide up to 5 stops of compensation, allowing for sharper handheld images and smoother video footage. A 5-stop IBIS system is a common standard in high-end full-frame mirrorless cameras, indicating that the SL3-S meets the expected stabilisation capability for still photography and video recording.

The video recording capabilities of the Leica SL3-S are extensive, catering to professional videographers. The camera can internally record up to 6K Open Gate (3:2 aspect ratio) at 30 frames per second. It also offers internal recording in the industry-standard ProRes 422 HQ codec at resolutions up to 5.8K at 30 frames per second. For users requiring maximum flexibility in post-production, the SL3-S provides a 5.9K HDMI RAW video output at 30 frames per second. Furthermore, the camera supports direct recording to an external Solid State Drive (SSD) via its USB-C port, facilitating efficient storage of high-resolution video files. The “Open Gate” recording feature, by utilising the area, offers significant advantages in post-production, enabling users to reframe shots and create various aspect ratios from the original footage. This is particularly valuable for content creators who must produce material optimised for platforms. Including internal ProRes recording is a significant benefit for professional videographers, as ProRes is a widely adopted, high-quality codec that streamlines post-production workflows.

Beyond these core features, the Leica SL3-S offers several other notable functionalities. It includes a 48-megapixel and 96-megapixel handheld multishot mode, leveraging the IBIS system to capture higher-resolution images without requiring a tripod in many situations. The camera also incorporates Content Credentials technology (CAI), allowing for the authentication of digital photos by embedding tamper-proof metadata. The SL3-S features dual memory card slots for storage, accommodating one CFexpress Type B card and one SD UHS-II card. The electronic viewfinder is a high-resolution 5.76 million-dot OLED display with a refresh rate of up to 120 frames per second, providing a clear and fluid viewing experience.

The rear display is a tilting 3.2-inch high-resolution touchscreen with 2.3 million dots, offering flexibility for shooting from various angles. The camera body boasts an IP54-certified weather-sealed construction, utilising a metal design made of magnesium and aluminium. Connectivity options include Bluetooth and Wi-Fi (with MIMO technology) for wireless data transfer and remote control. The camera has a comprehensive array of interfaces, including an HDMI 2.1 Type-A port, a high-speed USB-C port (10 Gbits), and 3.5mm audio input and output jacks.

A dedicated timecode interface is also present, facilitating professional synchronisation of synchronisation in multi-camera setups. Leica has announced plans to introduce Camera-to-Cloud functionality with Adobe Frame.io in 2025, further enhancing workflow integration. The camera utilises an L-bayonet, ensuring compatibility with a wide range of high-quality lenses from Leica, Panasonic, and Sigma, providing users with extensive lens options. Including a handheld multishot mode, made possible by the IBIS system, enhances the camera’s versatility by creating high-resolution images in situations where a tripod might not be practical. Furthermore, the integration of Content Credentials reflects an increasing awareness of the importance of digital content authenticity, positioning Leica as an innovator in addressing this concern. 

3. Design, Build Quality, and Handling:

The Leica SL3-S features meticulously crafted all-metal housing constructed from magnesium and aluminium, providing a robust and durable chassis. The exterior is finished with a synthetic leather cover, contributing to aesthetics and grip. The camera’s dimensions are 141.2 x 108 x 82.7 mm, weighing approximately 768 grams without the battery and memory card. Notably, the design is described as being lighter and more compact compared to its predecessors in the SL series, suggesting a focus on improved ergonomics and portability for users. The selection of premium materials and the all-metal construction are consistent with Leica’s long-standing reputation for producing cameras of exceptional build quality and durability. These materials are known for their strength-to-weight ratio, contributing to a solid feel without excessive bulk. The reduction in the camera’s size and weight compared to earlier SL models indicates Leica’s responsiveness to user feedback, aiming to enhance comfort and ease of use during extended shooting sessions.

The Leica SL3-S boasts an IP54 certification, signifying protection against dust ingress and water splashes from any direction. However, it is essential to note that achieving complete weather protection requires using a sealed lens. This level of environmental sealing provides a significant advantage for professional photographers and videographers who often work in unpredictable outdoor conditions, enhancing the camera’s reliability and longevity.

Regarding ergonomics and handling, the Leica SL3-S features a deep and comfortable handgrip, facilitating secure handling. However, some reviewers have noted that the shallower interior of the grip, lacking a sculpted indentation for the fingers, might not feel as safe as grips found on competing cameras, mainly when using heavier lenses. The camera employs a minimalist control layout characteristic of small, loosely labelled buttons with many functions assigned to customisable controls, emphasising a clean and uncluttered experience. The SL3-S has three large control wheels that provide satisfyingly clicky feedback, allowing for tactile adjustments of key exposure parameters. A top-plate 1.28-inch square LCD information panel offers at-a-glance access to essential shooting settings. Unlike traditional cameras with an on/off switch, the SL3-S utilises a power button, a design that users might find less intuitive due to the lack of a clear visual indication of the power state. The rear of the camera features a tilting touchscreen display, which, while improving the fixed screen of the SL2-S, does not offer the full articulation favoured by some videographers. The placement of the ISO dial on the top left of the camera body has been noted as potentially awkward, requiring the user to shift their left hand from supporting the lens to make adjustments. The camera inherits customers’ customisable menu screen, customising frequently used settings.

 Furthermore, the menu system has been simplified, aiming for a more rationalised minimalist design and highly customisable customcustomizedols that reflect the user’s customisation to a bespoke and adaptable user interface. At the same time, this approach can lead to a personalised experience, a personalised degree of familiarity for users with custom familiarised controls. The tilting screen offers enhanced versatility for shooting from high and low angles. Still, the lack of full articulation might be a limitation for solo videographers or those who frequently monitor themselves while recording. The positioning of the ISO dial could potentially interrupt the shooting flow, especially when using larger lenses that necessitate consistent left-hand support for stability.

The Leica SL3-S features a high-resolution 5.76 million-dot OLED electronic viewfinder (EVF) with a magnification of 0.76x. The EVF offers a selectable refresh rate of 60 or 120 frames per second, providing a smooth and detailed view of the scene. While generally described as clear, sharp, and with accurate colour rendition, some reviews suggest it falls slightly short of being the best EVF available in the high-end camera market. The rear display is a tilting 3.2-inch touchscreen with a resolution of 2.3 million dots. One reviewer noted that the brightness of the rear screen might not be sufficient for comfortable viewing in bright outdoor conditions. While the EVF specifications are impressive, the subjective assessment that it is “not the best around” indicates that in the context of a premium-priced camera, users have high expectations for all aspects of the viewing experience. Factors such as contrast, dynamic range, and overall clarity contribute to the perceived quality of an EVF. The potential inadequacy of the rear screen’s brightness could impact the user’s ability to accurately compose shots and review images and videos outdoors in bright sunlight.

4. Image Quality Analysis:

At the core of the Leica SL3-S is a 24-megapixel full-frame BSI CMOS sensor. Notably, this sensor shares similar specifications for still photography, video recording, and burst shooting with the Panasonic Lumix S5 II sensor. Compared to its predecessor, the SL3-S offers a broader range of sensitivity settings, extending from ISO 50 to 200,000. In line with Leica’s commitment to capturing maximum detail, the sensor does not incorporate an optical low-pass filter. The close resemblance of the SL3-S’s sensor to that of the significantly more affordable Lumix S5 II raises questions about the primary drivers of Leica’s premium price point. This suggests that factors beyond the sensor, such as build quality, user interface design, brand reputation, and specific feature implementations, contribute substantially to the camera’s cost.

The Leica SL3-S offers a dynamic range of 14 or 12 bits, depending on the selected drive speed. Shooting up to 5 frames per second allows for 14-bit capture, while higher speeds from 7 fps upwards utilise depth—Leica emphasises. Reviewers have observed a good tonal range in JPEG images, from deep shadows to bright highlights. One review noted that the dynamic range of the SL3-S appears to be significantly improved compared to the previous SL2-S model. The option to capture images in 14-bit RAW format at lower frame rates caters to photographers who prioritise maximising images. The shift to 12-bit capture at higher continuous shooting speeds represents a necessary trade-off to maintain performance, as processing larger 14-bit files at high frame rates demands significant processing power.

Leica is known for its distinctive colour science and supports this reputation. Reviewers have praised the excellent quality of the JPEGs produced by the camera, and Leica themselves highlight the superb colour rendering capabilities. Including “Leica Looks”, users will have creative in-camera processing options. As with dynamic range, one review indicated that the colour rendition of the SL3-S is notably better than that of the SL2-S. One user even cited Leica’s colour science as a primary reason for choosing the camera, despite acknowledging limitations in the autofocus system. Leica’s established expertise in colour reproduction is a significant draw for many users, who value their camera’s aesthetically pleasing colours, often requiring minimal adjustments in post-production.

The Leica SL3-S is advertised as having exceptional low-light performance. Due to its lower resolution sensor than the 60MP Leica SL3, the SL3-S is expected to perform better in dimly lit environments. Real-world tests have shown that noise levels remain remarkably low even at high ISO settings, such as ISO 6400. Some reviews suggest usable images can be obtained even at ISO 100,000, and with noise reduction software, good results might even be achievable at the maximum ISO of 200,000. The combination of a back-illuminated sensor design and a relatively lower pixel density contributes to the excellent low-light performance of the SL3-S. BSI sensors are known for their improved light-gathering capabilities, and larger individual pixels (as found in a 24MP full-frame sensor compared to a 60MP one) can capture more light, resulting in lower noise at high ISOs.

The Leica SL3-S incorporates a 48MP and 96 MP handheld multishot mode, which utilises the camera’s in-body image stabilisation, multiple images and single, higher-resolution files. This feature is based on technology developed by Panasonic and is considered genuinely usable in practical shooting scenarios. The camera offers options for motion compensation within the multishot mode. However, some reviewers have noted that the detail around moving subjects might appear somewhat fuzzy when shooting handheld with motion compensation enabled. Consequently, the multishot mode is generally best suited for capturing static subjects where no movement occurs during the capture process. Rather than being restricted to a tripod, the ability to use the multishot mode handheld significantly enhances its practicality and expands the range of situations in which it can be effectively employed. However, users should be mindful of potential artefacts when capturing scenes with movement. They might need to choose between sharper detail in static areas and dealing with motion blur or artefacts in dynamic parts of the frame.

5. Autofocus Performance Assessment:

The Leica SL3-S employs an advanced hybrid autofocus system that integrates Phase Detection Autofocus (PDAF), contrast detection, and depth map-based object detection. This system utilises a comprehensive array of 779 autofocus points across the sensor. Furthermore, the autofocus utilises tracking subjects, specifically recognising heads, faces, ayes, and animals. The sig recognition in autofocus points compared to earlier Leica SL models, such as the SL2-S, suggests a more granular and potentially more responsive autofocus performance. A more significant number of focus points allows for finer control over the precise area of focus and can contribute to improved tracking of moving subjects across the frame.

Leica markets the SL3-S as its fastest camera to date. Indeed, reviewers have noted much faster shot-to-shot times with autofocus engaged compared to the previous SL2-S. The single-shot autofocus performance is generally described as quick and effective, capable of acquiring focus quickly and accurately. Moreover, the autofocus performance in low-light conditions has reportedly been significantly improved compared to the Leica SL3. These improvements suggest that Leica has made considerable strides in addressing a common area of criticism regarding the autofocus capabilities of their earlier SL series cameras.

For capturing dynamic subjects, the Leica SL3-S offers continuous shooting at up to 30 frames per second with continuous autofocus (AF-C) when shooting in 12-bit RAW format. While the tracking performance is reported to work reasonably well even at this high frame rate, it is not considered infallible. It may not be as consistently reliable as the autofocus systems found in cameras with stacked sensors. Independent reviews suggest that the dependability of the continuous autofocus and subject tracking in the SL3-S falls somewhere behind the performance of top-tier competitors, exhibiting characteristics similar to Panasonic’s autofocus systems. One reviewer described the autofocus as more reactive than proactive when compared to systems from Canon or Sony, implying that it might take a moment to initially acquire and then track a moving subject rather than anticipating its movement with the same level of algorithmic sophistication seen in some other leading camera brands. However, eye and face detection for people and animal detection are reported to function quickly and accurately when the subjects are not moving at very high speeds. Although the burst shooting speed with continuous autofocus appears impressive, subjective assessments suggest that the SL3-S may not provide the highest autofocus tracking performance available in the current market for users primarily focused on capturing extremely fast-paced action. 

Real-world usage examples provide further context to the autofocus performance. One user reported excellent AF-C performance when shooting a middle school basketball game, noting that the focus was “much stickier” than on the SL3 and recovered quickly even when a referee briefly obstructed the view. This suggests that in specific dynamic scenarios, the autofocus can perform admirably. The low-light autofocus significantly improves the SL3, enhancing usability in challenging lighting conditions. However, in video mode, the autofocus is reported to feel somewhat less responsive compared to stills, and it is described as less predictive, performing best when the user explicitly directs it where to focus. This suggests that while the autofocus system has seen considerable improvements for still photography, its video performance might require a slightly more deliberate approach from the user.

6. In-Body Image Stabilisation (IBIS) Review:

The Leica SL3-S is equipped with a 5-axis in-body image stabilisation system rated to provide up to 5 stops of shake reduction. World testing by Revitalisation shows that the system reliably delivers its maximum ion. This makes the SL3-S a stable platform for capturing stabilisation images and n. The IBIS system is also effective for video recording and can smooth out careful camera movements and even some walking while filming. However, more pronounced movements might result in some “choppy” footage. The consistent performance of the IBIS system in delivering its advertised effectiveness is a significant benefit for users who frequently shoot handheld in various conditions.

The in-body image stabilisation (IBIS) system enables the Leica SL3-S’s 48MP and 96MP handheld multishot modes. By stabilising multiple frames, the IBIS system allows the camera to create higher-resolution images without needing a tripod in many situations. This integration of IBIS with the multishot functionality significantly enhances the practicality and versatility of this feature, making it more accessible for a broader range of shooting scenarios.

7. Video Recording Capabilities and Performance:

The Leica SL3-S offers a comprehensive suite of video recording options, catering to a broad spectrum of production needs. The camera can capture footage in resolutions up to 6K using the Open Gate (3:2 aspect ratio) mode at 30 frames per second. Additionally, it supports C6K and standard 6K (16:9) recording at up to 30 frames per second in a 4:2:0 10-bit colour space. For 4K resolution, the SL3-S can record up to 60 frames per second, although this mode utilises an S-C sensor crop. Uncropped 4K and C4K recording is available at frame rates of up to 30 frames per second and uses a camera which offers Full HD recording of up to 120 frames per second for slow-motion captures. The range of resolutions and frame rates provides considerable creative flexibility for various video projects. 

The Leica SL3-S supports high-quality video codecs, including internal recording in ProRes 422 HQ at resolutions up to 5.8K at 30 and C4K at 60 frames per second. It’s important to note that ProRes recording requires using a CFexpress Type B memory card due to the high data rates involved. The camera also offers HDMI RAW video output up to 5.9K at 30 frames per second for maximum post-production flexibility. A handy feature is recording directly to an external SSD via the USB-C port, especially when working with demanding codecs like ProRes. The camera also supports internal recording in H.264 and H.265 codecs. In particular video modes, such as ProRes 4:2:2 HQ in 5.8K at 30 fps or C4K at 60 fps, the SL3-S offers unlimited recording times, removing a common constraint in video production. The availability of professional-grade codecs like ProRes and RAW, combined with the convenience of direct SSD recording and the absence of recording time limits in key modes, positions the SL3-S as a strong contender for professional video applications.

A standout feature for video production is the 3:2 Open Gate recording mode in 6K resolution. This utilises the entire sensor area, providing significant flexibility in post-production for cropping to various aspect ratios, including utilitarian formats like 4K 9:16, without losing quality. This feature also allows the field of view to be determined retrospectively during editing. The Open Gate recording capability is a significant advantage for modern content creators who often need to deliver video in multiple aspect ratios for different social media platforms and viewing devices.

The Leica SL3-S is well-equipped with connectivity options and interfaces essential for video production. It features a full-size HDMI 2.1 Type A output, allowing for high-quality external monitoring and recording. Dedicated 3.5mm microphone input and headphone output jacks are provided for professional audio capture and monitoring.

The USB synchronisation direct synchronisation supports power delivery, adding to the camera’s versatility on set. Including these industry-standard video interfaces highlights Leica’s commitment to providing a camera suitable for professional video workflows.

Regarding overall video quality and performance, the Leica SL3-S is reported to produce “truly nice” images with a pleasing texture. Its low-light video capabilities are good, with usable footage even at ISO 8000. The L-Log colour profile offered by the SL3-S is noted to be more similar to that of Sony cameras compared to previous Leica models. However, some reviewers have pointed out the potential for rolling shutter artefacts, particularly during fast-moving scenes. A notable drawback mentioned in several reviews is the less-than-ideal battery life when recording video. Additionally, the menu system for video settings has been described as potentially unintuitive, with some parameters adjusting automatically in a way that might not be immediately clear to the user. While the SL3-S offers impressive video specifications and generally good image quality, the limitations in battery life and the reported complexities of the video menu system could be areas of concern for professional users who require consistent performance and efficient operation in demanding shooting environments.

8. Real-World Performance and User Experience:

The overall shooting experience with the Leica SL3-S is frequently described as “exquisite” and a “joy”, with a user interface that facilitates a seamless connection between the photographer’s vision and capturing an image. Reviewers praise the friction-free interface and the intuitive nature of the menus and controls. The user interface has been optimised for navigation, with clear distinctions between photo and video functions, and it dynaoptimises in either landscape or portrait orientation, depending on the camera’s position. This emphasis on user experience suggests that Leica has a proprietary camera that is capable and a pleasure to use, which is an essential consideration for professionals who spend copious time behind the lens.

In practical handling, the Leica SL3-S is reported to feel substantial and well-built, instilling confidence in its robustness. Customisations and dials allow users to tailor the camera’s operation to their specific shooting and enhance workflow.

Some users have noted the potential for accidental changes to the focus point due to the touchscreen interface. Solid construction and user-configurable controls allow for a high degree of personalisation of the ring according to individual shooting styles and preferences.

The Leica SL3-S is consistently the fastest Leica Leicpersonalization, offering quicker shot-to-shot times than its predecessor when it is engaged in recognition autofocus, which is described as rapid and effective in acquiring focus. These improvements in speed and responsiveness address a common point of feedback regarding earlier Leica SL cameras, making the SL3-S a more competitive option for capturing dynamic subjects and ensuring that the camera can keep pace with demanding shooting scenarios.

9. Competitive Comparison:

Several emerge compared to the Sony A7R V, which shares the same 60MP sensor as the Leica SL3 (not the 24MP SL3-S)—the S offers superior in-body image imagstabilizationon rated at eight compared to Leica’s 5. However, post-processing is required for the stabilisation and pixel-shift stabilisation of even higher-resolution images. While the Leica SL3 (and likely the SL3-S) can achieve a faster burst rate in ideal conditions (15fps vs. fps), this advantage diminishes when continuous autofocus and whole bit depth are required. The design philosophies of the two cameras also differ significantly, with Tony adopting a “more is more” approach with numerous buttons and dials; simultaneously, he emphasises a more minimalist design with a greater reliance on the touchscreen interface. The Sony features an emphasis and a higher-resolution electronic viewfinder. Furthermore, the Sony E-mount boasts a broader selection of available lenses. Perhaps the most significant difference is the price, with the Sony A7R V being considerably less expensive than the Leica SL3-S.

Compared to the Canon EOS R5 (and its successor, the R5 Mark II), which is similarly priced and competent, the Leica SL3-S presents a distinct set of trade-offs. Comparisons on platforms like CameraRace suggest that the Canon EOS R5 Mark II is technically superior overall and performs better across various photography genres. The Canon R5 offers a higher resolution sensor (45 MP vs. 24 MP) and a fully articulated rear screen.
