Like Panasonic’s mirrorless cameras, it uses contrast-sensing autofocus with depth mapping. This usually gives precise autofocus for objects that aren’t moving too much, but it’s not ideal for fast-moving subjects or videos. Also, it can only handle 5 fps shooting with continuous autofocus enabled, so 25 fps shooting speeds are limited to fixed autofocus with the electronic shutter . With the mechanical shutter, it can shoot 9 fps without continuous autofocus.
The SL2-S handles video very well, with specifications still similar to those of the Panasonic S1. You can shoot in 4K at up to 60 fps via APS-C cropping, with 8-bit 4: 2: 0 internal and 10-bit 4: 2: 2 external recording. Full-frame 4K shooting is possible at up to 30 fps with 10-bit 4: 2: 2 recording both internally and externally. Images should be sharp in this mode as they are downsampled from a 6K sensor area. It also supports V-Log and HLG recording for HDR work or to maximize dynamic range, and there is no limit on recording time.
Leica uses its own image processor and its own menu system similar to those of the SL2. While a little confusing compared to the S1’s tabbed menus, it gives you easy access to your preferred settings on the first page. It also includes a Cine mode that lets you quickly switch between photo and video settings.
The German company has promised firmware updates next year that will improve autofocus, especially in the area of eye / face and body detection. They will also enable 10-bit internal 4K at 60 fps through the use of a more efficient HEVC (H.265) codec.
It works with the L-mount lens system supported by Panasonic and Sigma, offering 40 compatible native lenses. The Leica SL2-S is now on sale at authorized Leica dealers for $ 4,895.
