Dpreview tests the A7rII and RX100m4 Eye AF: “has far more accuracy than a DSLR!”.


Sony a7R II – Eye AF (AF-C)

Dpreview posted a full A7rII and RX100m4 Eye AF testing report. You can see the videos on Youtube:
Sony a7R II – Eye AF (AF-C) (video embedded on top of this post).
Sony a7R II – Continuous AF with Sigma 50mm F1.4 (Canon EF Mount)
Sony RX100 IV: Eye AF (AF-C)

Their conclusions are rather impressive:

1) A7rII with adapted 50mm Sigma EF lens: In fact, it’s this accurate phase-detect AF that allows the a7R II to focus the Sigma 50mm F1.4 lens with far more accuracy than a DSLR. We have to microadjust F1.4 primes all the time on DSLRs to get accurate focus out of them, and even then, peripheral AF points may continue to be off

2) A7rII with 24-70mm FE lens: The camera automatically finds the nearest eye, and continuously focuses on it, despite rather drastic and fast movement along the X, Y, and Z (distance) axes. No hunting, no jumping off to some other subject, just fast and effective AF on Richard’s eye.

3) Eye AF on the RX100m4: it’s really, really good, especially when you consider the RX100 IV has a contrast-detect only AF system.
