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

这个有些误导
sigma的副厂头对焦上的兼容性历来不好,在a7rii上转接效果好过在c、n上,
并不说明太多问题
但标题看起来却像是C/N原厂头在a7rii上也要比各家自己机身上表现还牛逼一样

听说a7r ii转接对焦不能选择单点对焦什么的,只能用全屏自动对焦,也不知道是不是
真的。
真的很期待大法这几年继续革命下去会产出什么样的相机。

单反太复杂,成本高。还容易跑焦。
