With the SL2-S, Leica has introduced a new version of its professional, mirrorless full-frame system camera, which differs from the 48MP Leica SL2 mainly in the sensor used: a sensor with 24MP resolution is installed, as in the first SL model, but here it is a new CMOS BSI sensor (pixel pitch: 5.94 μm; no low-pass filter).
As with the 
SL2, this is moveably suspended, so that an efficient 5-axis image stabilization is available. Sensor shift technology is also used again in the photo area for multishot shots, in which eight tripod shots are processed into one image with four times the resolution of 96 megapixels. Thanks to the new Maestro III processor in combination with a buffer memory of 4 gigabytes, almost unlimited JPEG image series with up to 9 frames per second are possible.
The SL2-S films with full sensor area in Cinema4K resolution at up to 29.97fps, and also at up to 59.97fps in an APS-C window. A 4:2:2 / 10-bit sampling is available throughout with HDMI output as far as we can see, likewise with internal recording to SD card, except in the 4K formats above 29.97fps. The recording time for video is unlimited according to Leica. Filming can be done in L-LOG (viewing LUTs are integrated), and HLG Rec. 2020 is also on board. Sensitivity ranges up to ISO 100,000.
In the future, the camera should also support HEVC video compression for 10-bit recording up to 4K/60p, and a waveform display and automatic follow focus should also be added via firmware update.
The camera's user interface guides through photo and video functions separately. Both a microphone input (3.5 mm jack stereo incl. supply voltage (approx. 2.5 V) and a headphone output are available.
The Leica SL2-S with L-mount, which is protected against dust and water according to the IP54 standard, is available immediately for a recommended retail price of 4500 euros.
