A7 IV – What’s new

We spent a great deal of time with Sony at a (virtual) press event earlier this week going over all the new features of the A7 IV. We made a long list of all the new features in the A7 IV which encompass almost every major aspect of the camera.

  • *All new* 33MP Full-Frame CMOS sensor (with BSI technology).
  • New BIONZ XR processing engine (similar to one found on the A7S III/A1 and 8x faster than that of the A7 III).
  • Increased sensitivity 100-51200 ISO.
  • Huge new buffer with up to 828 RAW+JPEG uncompressed images (max shooting speed is still 10fps).
  • Improved AF system – 94% frame coverage, eye AF on people, animals, and birds including in video, and improved tracking.

There is one small drawback compared to the original A7 III – battery life is rated at 610 images (CIPA) – lower than the A7 III (using the same Z type battery), but Sony explains that the new sensor/processor and EVF draw more power and actual field performance should be very good like its predecessor.

The way we see it, the A7 IV is an expected update to an already very capable camera that in many respects is still relevant today, years after it was announced. This is especially true for stills shooters. For video shooters, however, Sony offers a lot of important updates with the A7 IV and provides more enticing for an upgrade.

2 new flashes – Sony HVL-F60RM2 and HVL-F46RM

Sony also announced today two new advanced flashes:

  • HVL-F60RM2 – a powerful on-camera flash with a Guide Number of 60, 20mm-200mm zoom, up to 200 flashes at 10fps (or 20 fps on a fast burst with the A1 and up to 1/400 sync speed). New angle mechanism, sync terminal, improved TTL operation, stronger shoe (with better sealing), and up to 240 flashes per charge or 720 with a special Sony external battery.
