I have the A7R, and Iím not sure Iíd want to use it for event shooting because of the very loud, long duration shutter sound. Also, with the noise comes vibration, so that may also be an issue at slower shutter speeds. It is something you want to check while you have the camera. Lloyd Chambers at Diglloyd posted more info on it last night, and Iíve had a lot of email on this subject where people are testing different lens/adapter combinations.
I have a question about LAEA-4 (I assume that is the A lens to E mount adapter - I donít have it with me to check to see). I tried it on the A7R with the Sony 70-400 zoom the other day. I have the single focus point, small size, chosen in the A7R menu, but when I used the 70-400 in AF mode, I saw a viewfinder full of focus points, and the lens/camera combination ďdecidedĒ which of these AF points to choose. It was frustrating. Is there a way to manually select a focus point when using this adapter with A mount lenses? Also, this only works with the lens wide open - correct?
