Sony recently announced the RX10 II and the RX100 IV. Both cameras feature the same stacked 1-inch CMOS sensor as the Sony a7R II, and both have a fixed zoom lens from Zeiss.

The $1300 RX10 II (below) has a Carl Zeiss 24-200mm f/2.8 Lens (35mm equivalent.)

These are fixed lenses which cannot be changed. Both cameras are capable of shooting 4K video internally to XAVC-S. This is a new Sony format which can support 4K resolution (4096 × 2160) at up to 60 frames per second.

The cameras also use Sony’s S-Log2. This is a log gamma which allows the capture of a much greater dynamic range than is possible when shooting with conventional television gamma. Dynamic range is the range from light to dark that the camera can capture or the range that the monitor or TV can display within one image. It is the range from the deepest blacks to the brightest whites that can be captured or shown at the same time. To be seen on a TV set, however, the range must be somewhat compressed. Even so the result is still a greater dynamic range, but it will take a little study to utilize the increased range.

But the most amazing feature of these two cameras is that both shoot 960 fps at 24p or 1000fps at 25p.
