Sony a7 IV has a new image sensor and better autofocus

This is what the successor to the Sony a7 III looks like. It’s not easy to see what’s new, but this time the upgrades are actually very important.

After all, the new Sony a7 IV replaces a camera that’s almost four years old, so it’s no surprise that we’re talking about more than just small changes.

Sony’s new and greatly improved menu system is available in the a7 IV. The same is true of a new full-frame sensor with 33MP, a better periscope with 3.7MP and a 1MP rotatable touchscreen.

This is not all. An image stabilizer with 5.5 steps is included. So does Sony’s Real Time Eye focus system, and of course 4K video. Frame rate is 10 frames/sec.

4K/30p video is retrieved from a 7K video stream, in 10-bit 4:2:2 or 4:2:0 colors, with either H.265 or H.264 compression, with Long GOP or H.264 All-I compression.

The camera has a Super 35 4K cropping with up to 60 pixels, and the smart video function is auto focus compensation for focus breathing. So the partition does not change when focusing.

Physically, we’re still talking about a relatively compact full-frame camera. 658 grams more than certified, and two card slots that support SD cards with UHS-II – one also with CFexpress A – are good. The same can be said for the USB-C port with charging, support for a network connection of up to 10 Gb / s, and a full-size HDMI connector.

If you look closely, you will find a new switch under the program wheel. With it, you can quickly switch between still images and video, and the flash stand on top has a Sony multi-connector for accessories like a microphone or a microphone adapter.

The new Sony all-in-one camera costs SEK 29,000 for the camera body and SEK 31,000 for the set with the camera body and an unmarked lens. Sales start in December.

In the previous month, two new flashes were released. HVL-F60RM2 and the smaller HVL-F46RM. They have essentially the same characteristics, however, the F6o is larger, more powerful and covers 24-200 mm, while the F46 covers 24-105 mm.

The F60 can fire four out of 200 flashes in a continuous series at 10 bits per second, when the light is set to 1/32. The F46 can handle 60 flashes. Both support wireless flash control.

The cost of the HVL-F60RM2 is 6700 kroner, and the HVL-F46RM 4400 kroner. Both come in November.
