| 33MP back-illuminated CMOS full-frame sensorCopper wiring contributes to higher transmission speeds and faster AD (analogue to digital) conversion. Fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance, 15+stop dynamic range and increased AF speed.

BIONZ XR image processor up to 8x processing speedThe BIONZ XR engine, also used in the Sony Alpha 1 and Alpha 7S III models, provides up to an 8x increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimize processing latency for greatly increased processing power. |

| 4K 60p recording and 4:2:2 10-bit recordingFull pixel readout without binning allows 4K 60p recording in Super 35 mode providing high-resolution smooth footage that can be edited to 2x and 2.5x slow-motion when rendered to 30p or 24p in post-production, and 4K 24p or 30p full pixel readout without binning in full-frame with 7K oversampling.

Beautiful color expression, with S-CinetoneThe Alpha 7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta professional cinema camera line. It delivers natural mid-tones for healthy-looking skin color, plus soft colors and gorgeous highlights.

 | Real-time Eye-AF for humans, animals, and birdsThe high speed of the latest image BIONZ XR processing engine provides a significant boost to Real-time Eye AF performance, even when the subject is looking up, down, or sideways. It is also possible to use Touch Tracking to initiate Real-time Tracking of any subject in the frame. |
Fast Hybrid AF with improved speed and tracking759 phase-detection AF points and 425 contrast-detection AF points with a wide coverage of roughly 94% of the image area for both stills and movie. This vast collection of data is analyzed in real time by the latest powerful BIONX XR processing engine to achieve the AF system's impressive results. |
