Sony F55

The Sony F55 looks identical to the Sony F5 but has a number of significant improvements under the hood to justify it’s steep price increase. Like the Sony F5, the F55 is a compact black box with an FZ lens mount that comes with a FZ to PL adapter. A viewfinder, battery, and lens must be purchased separately. Unlike the F5, the F55 is able to record XAVC 4K internally without a recorder.

The F55’s image sensor is the same super 35mm size and 4096 x 2160 resolution as the  one in the F5 but is significantly more advanced. The F55’s CMOS sensor has a global shutter, and no matter how fast you pan there won’t be any of the distracting motion skew that CMOS sensors usually suffer from. The global shutter does have a slight effect on the light gathering ability of the sensor leading to a slightly lower native ISO of 1250 for the F55, which is still rather high.

4K on the F55

The F55 is able to record 4K in two ways. Internally it can record in the XAVC video codec in both DCi 4046 x 2160 4k or QHD 3840 x 2160 in a variety of frame rates, color spaces, and bit depths. At 4:4:4 12 Bit XAVC 4K runs at 960 Mb/s. High speed SxS Pro+ cards are required to record the exceptionally high datarates. The F55 is also able to record compressed 16 bit RAW in DCi 4K onto AXS memory cards with the AXS-R5 recorder. RAW files from the AXS-R5 recorder run about 960 Mb/s at 24P, which is roughly the same size as XAVC at the highest settings. This will take up about 7.2 GB a minute and 432 GB an hour.
