分享剛才Google到的MC-11使用心得
作者說MC-11在A7R2、初代A7都如原生FE鏡般運作
在A6000上可以使用全部對焦點並能追焦快速移動物體
甚至在Nex-5N上都能快速準確的對焦
原文:
On the a7, it autofocused like a native FE mount lens. It was fast in good light and took advantage of the hybrid AFthe a7 didn’t default to a very slow contrast detection AF. The A6000 used all of the AF points and was able to track a fast moving subject. Even the Nex-5n’s older AF system performed well giving quick and accurate results.
