Lens detailZEISS Tessar T*, physical 7.7 mm; six elements in six groups, all aspherical. Fixed f/4 aperture; 24 mm equivalent applies to 3:2 stills. Digital and Clear Image Zoom crop the image rather than optically zoomingZEISS Vario-Sonnar T*; actual 8.8–25.7 mm; equivalent range applies to 3:2 stills; built-in three-stop ND filter
AutofocusAF-S, manual and preset focus; wide 25-point area, centre, flexible spot and expanded flexible spot, with Eye AF and lock-on tracking. Movie preset focus is for subjects beyond approximately 1 m; NEAR mode covers approximately 0.5–1 m. No continuous movie autofocusContrast-detection AF; single-shot AF, continuous AF, direct manual focus and manual focus; Lock-on AF and Eye AF
ShutterElectronic shutter, 1/4–1/32000 second in Auto, Program and ManualMechanical shutter permits Bulb and 30 seconds to 1/2000 second in manual mode; electronic shutter reaches 1/32000 second
Burst detailUp to 16 fps in speed-priority continuous mode with focus and exposure fixed to first frame; ordinary continuous mode approximately 5.5 fps. Speed decreases as buffer fillsSpeed Priority Continuous reaches approximately 16 fps with focus and exposure fixed at the first frame. Normal continuous shooting reaches approximately 5.5 fps.

Video
Highest video resolution1920 × 1080 at 60 fps3840 × 2160 at 25 fps
Video detailInternal XAVC S/AVCHD/MP4 Full HD recording up to 60p NTSC or 50p PAL; XAVC S 50 Mbps. Ordinary 120/100 fps recording is 1280 × 720, not Full HD. Clean 3840 × 2160 HDMI output requires a separate recorder; the camera cannot record 4K to its memory card. HFR captures up to 960 fps NTSC or 1000 fps PAL with reduced sensor readout resolution, scaled to Full HD playback; no audio in HFR. S-Log2 and picture profiles availablePAL 4K up to 3840 × 2160 at 25p; NTSC up to 30p or 24p, at 60 or 100 Mbps; 4K clips limited to approximately five minutes. Full HD supports 100p PAL or 120p NTSC. Separate HFR captures at 250/500/1000 fps PAL or 240/480/960 fps NTSC for approximately two or four seconds, then encodes Full HD slow motion; these are lower-resolution sensor readouts, not native Full HD at 1000 fps.
AudioBuilt-in stereo microphones and 3.5 mm stereo microphone input with plug-in power; external microphone disables internal microphones. XAVC S uses LPCM stereo, AVCHD Dolby Digital stereo and MP4 AAC-LC stereoBuilt-in stereo microphone; LPCM, Dolby Digital or AAC audio depending on movie format; HFR recording has no audio

Release detailSony Japan's 1 September 2017 announcement specifies 27 October local sale; October precision retained pending exact earlier international retail-day evidence. September preorder and demonstrations are separate from saleSony specifies July 2015 US retail availability and 31 July 2015 in Japan. The month is retained because the US notice supplies no day. Sony's Japanese announcement expands the RX range rather than retiring earlier models.
