Camera overview 

At the heart of the Leica SL3-S is a 24MP full-frame sensor, which is optimised for speed and video capture. The camera’s Open Gate 6K (30fps max.) recording mode allows you to shoot across the full height and width of the sensor, providing the flexibility for reframing in various aspect ratios when editing in post-production. This feature is particularly appealing for anyone who produces content for various platforms, including vertical and square formats for social media.

The SL3-S also offers 10-bit internal recording, for professional colour depth and detail, and includes support for industry-standard codecs like ProRes. These make it an excellent choice for filmmakers, videographers, and hybrid creators looking to elevate their production quality with industry standard features.

The autofocus system has also seen significant improvements, and now features enhanced subject tracking that excels in both stills and video. Paired with 5-axis in-body image stabilisation, the SL3-S provides smooth and sharp results, even when shooting handheld.

The camera is still made in Germany to the same robust weather-sealed level as its predecessor, and is a rugged option that works both in the studio and for outdoor environments. Its high-resolution OLED electronic viewfinder and intuitive interface further enhance the shooting experience, whether capturing photos or video.

Body Design and Ergonomics

The SL3-S features a refined design, making it slightly smaller and almost 100g lighter than its predecessor. Weighing 768 g (without battery, SD card, and body cap) compared to the SL2-S’s approximate 840 g, the SL3-S is more portable, while maintaining its striking design with a blacked Leica logo and weather resistant IP54 rating.

An updated button layout and an ergonomic grip improve handling, making it more intuitive for handholding or for extended shooting sessions. Leica has also introduced a tilting LCD screen, a much-requested feature that enhances flexibility for high and low-angle compositions.

Additionally, the updated menus ensure consistency across Leica’s camera range, streamlining navigation for users familiar with their system. These refinements ensure the SL3-S feels as good in hand as it performs intuitively.
