EFCS and Bokeh — a7RII with Sony 90/2.8 macro
There are some exposure variations at higher speeds. We expect this. The bokeh differences appear to be minimal to me. However, in theory, there should be bokeh effects of EFCS at high speeds, since the electronic first curtain is in a different plane than the mechanical first and second curtains. Thus, depending on the characteristics of the lens the subject distance, the f-stop, and the place where you look in the image, we should see some differences. They don’t appear to be important here — the exposure variation is more noticeable — but they probably would be at higher shutter speeds.
