#Sony alpha a7 iv full frame mirrorless camera 1080p
You can do video and audio streaming over USB-C at up to 1080p 60 or 4K 15p if resolution is a priority over smooth video. It also offers faster transfer speeds with 5GHz WiFi and superspeed USB-C 3.2 Gen2 (10Gbps). If you use Sony's Imaging Edge mobile app, it will now use Bluetooth to maintain a continuous connection, rather than disconnecting as before. Lastly, Sony has introduced new live streaming and sharing features, though they're not quite up to the level we've seen on other recent cameras. That means more tenacious tracking, along with faster and more accurate eye AF for humans, animals and birds. It also comes with the same AI-powered image tracking that can process spatial information "in real time at high speed," Sony said. Powered by the A1's BIONZ R processing engine, it offers the same 759 phase-detect AF points as the A1 with around 94 percent sensor coverage. However, the A7 III was limited to around 90 RAW frames at a time, but the A7 IV can shoot an incredible 828 uncompressed RAW+JPEG images in a burst, provided you capture to a CFexpress Type A card. However, it doesn't offer the stacked chip-on-sensor technology of the A1 and A9/A9 II, so it lacks the sensor readout speeds of those models.Īs such, the A7 IV is limited to the same 10 fps shootings speeds as the A7 III, both with the mechanical and electronic shutter - whereas the A1 can shoot at triple that speed. The 33-megapixel backside illuminated (BSI) sensor provides a significant resolution boost over the A7 III's 24.1-megapixel sensor, while still offering good low-light sensitivity, Sony told Engadget.
