A7s and Metabones Smart Adapter IV


I just wanted to make a quick summary of my experience with the Metabones Smart Adapter and my A7s that had their first meeting yesterday.

My Lenses

Canon EF 24-70 L II USM

Canon 300 L F2.8 IS USM

Canon 70-200 L F4 IS USM

Canon 100 L IS Macro

In good light conditions I get the focus nailed 1 out of 20. In dull light I get ZERO.

in fact, the AF is not slow, it is just useless.

The second issue I encounter, is when the 300L is on, the A7s switches to APS-C mode.

I am using the latest firmware for cam and for the Smart Adapter.

I have informe Metabones and I'll be waiting for their feedback.
