There's a new dedicated Stills/Movie switch, something I've come to love because pulling movie modes out of the exposure mode dial means there's more room for custom settings. In the case of the S1R II, you can have a total of 10 custom photo and 10 custom video setting stored. Sensor and AutofocusPhotograph: PanasonicThe S1R II uses a new sensor, which is actually lower-resolution than the 47-megapixel sensor in the S1R and considerably less than the 61-megapixel sensor chip that's in Leica's SL3. The S1R II's sensor is capable of 40 frames per second with the electronic shutter, 10 fps mechanical. On the video side, the S1R II can shoot 8.1K 30p and is capable of full-sensor-width 5.9K at 60p, with capture in ProRes 422, ProRes RAW, or H.265/264.
