The Leica SL3-S, the latest addition to Leica’s mirrorless lineup, combines speed and precision, making it a compelling choice for photographers and videographers alike. This Leica SL3-S review explores how the sister model to the SL3 emphasizes enhanced performance with a new back-side illuminated (BSI) CMOS sensor featuring a native resolution of 24.6MP, capable of producing up to 96MP photos using pixel shift technology.
Key Features
The SL3-S boasts a continuous shooting speed of 30fps with full autofocus support, making it the fastest Leica system camera to date. Video capabilities include up to 6K recording with open gate video, ensuring maximum flexibility for cropping in post-production. The dual ISO range from ISO50-200,000 offers exceptional low-light performance. The camera also supports direct recording to an external SSD via its USB-C port, adding further flexibility for professional workflows.
A standout feature is the robust build quality with IP54 weather sealing, paired with a split CFexpress B / UHS-II SD card slot for efficient data handling. The electronic viewfinder delivers 5.76 million dots with a 120fps refresh rate, while the 3.2-inch LCD screen offers 2.33 million dots for sharp image review. The high-resolution EVF ensures critical focusing accuracy, a key benefit for professional use.
Performance and Handling
The SL3-S’s usability excels with its intuitive controls and modern autofocus system, combining phase detection, contrast detection, and object mapping. This setup ensures precise focus even in challenging conditions. The camera’s low-light performance, even at ISO 8000, remains impressive, making it suitable for diverse shooting environments.
The SL3-S offers video recording up to 6K resolution with open gate mode, ideal for filmmakers seeking post-production flexibility. Its BSI sensor improves dynamic range, while the dual base ISO provides enhanced noise control in varying lighting situations. Internal ProRes recording with 4:2:2 color sampling enhances post-production grading capabilities.
However, some limitations exist. The camera’s high frame rate recording above 60p is restricted to Full-HD resolution, and 4K at 60p is limited to a cropped APS-C mode. While the image stabilization is effective for handheld shooting, it struggles with motion-heavy scenarios.
Build Quality and Ergonomics
The SL3-S retains Leica’s signature craftsmanship, featuring a rugged magnesium alloy body with IP54 weather resistance. The new control layout simplifies access to shooting modes, and the ergonomic grip ensures comfortable handling during extended use. The dual card slot system—CFexpress B and UHS-II SD—supports high-speed data recording.
Leica SL3-S vs SL3 and Competitors
Compared to the SL3, the SL3-S emphasizes speed over resolution, offering 30fps burst shooting versus the SL3’s 15fps. It also includes open gate 6K video recording absent from the SL3. Against competitors like the Panasonic Lumix S5 IIX, the SL3-S shares many features but offers a higher resolution EVF and more robust build quality.
