When I tested the A7IV with a 300MB/s V90 SDXC card, I was able to shoot at 10fps for 197 Extra Fine Jpegs. Also, if you want to shoot uncompressed raw and Jpegs simultaneously, provided a CFexpress Type A card is in use, you can get up to 828 images in one sequence. The ability to shoot at 10fps for 68 images with a 61Mp camera is pretty impressive, but it’s something you might want to do with caution as your memory card and computer storage are likely to fill up quickly.ģ3Mp images are more manageable, which makes the A7 IV a more natural choice for keen sport and action photographers.

And if you drop the frame rate to 30p, you can shoot 4K video using the full sensor with 7K oversampling.Īlthough the A7R IV can shoot 4K 30p video using the full sensor, it uses line skipping so the best results are captured when the Super 35 crop is applied. While you have to use the Super 35 crop to shoot 4K video at 60p with the A7 IV, you also get 600Mbps.

In another plus for the A7 IV, its AF system is more sensitive, operating at down to -4EV rather than -3EV with the A7R IV. In video mode, the A7R IV can only detect human eyes but the A7 IV can locate and track human, animal or bird eyes. The two cameras also have sony’s Real-time Eye AF which in stills mode can be set to detect human or animal eyes on the A7R IV, and human, animal or bird eyes on the A7 IV. These points cover 94% of the A7 IV’s imaging area while the A7R IV’s cover 99% of the height and 74% of the horizontal area.

Consequently, the A7 IV has a higher maximum ISO setting than the A7R IV and it produces cleaner images as the ISO value climbs. Having a lower resolution than the A7R IV gives the Sony A7 IV an advantage in low light as its pixels are larger so they gather more light and generate a stronger image signal. It means that you can make significantly larger prints or more dramatic crops if you can’t get close enough to your subject.īeing a more recent introduction, the A7 IV features the newer Bionz XR processor while the A7R IV has the older Bionz X processor. However, the Sony A7R IV has a 28Mp higher resolution than the A7 IV, which is an increase of around 46% in pixel count.

With an effective pixel count of 61Mp, it is the highest resolution full-frame mirrorless camera currently available and it’s capable of capturing a fantastic level of detail. Sony announced the A7R IV in July 2019 to replace the 42.4Mp Sony A7R III.
