Maker buffer at least 60 RAW/RAW+JPEG or 999 JPEG under specified conditions; reduced-resolution 6K/4K Photo modes are separateUp to approximately 10 fps in Hi+ with AF/AE tracking; approximately 8 fps in Hi. Sony lists 68 compressed RAW or 30 uncompressed RAW frames under its test conditions. Speed and buffer depend on settings and lens; some lenses need firmware updates.

No fixed recording limit within supported operating/power/storage conditions. Digital Camera World's suggestion that 6K requires Super 35 crop conflicts with the maker's full-sensor table and is not adoptedJapanese specification lists XAVC S 4K at 30p or 24p and up to 100 Mbps; headline maximum reflects Japanese/NTSC mode. Super 35mm uses full-pixel readout without binning with a narrower field of view; full-frame 4K is a separate mode. HLG, S-Log2 and S-Log3; 8-bit 4:2:2 HDMI output. Full HD 120p is a lower-resolution mode.
