Well, I've just made a discovery that should have been more obvious to me earlier. After complaining like a lot of users that my Leica M to E-mount adapter focused past infinity, I made another discovery today. My Sony issued A-mount to E-mount adapter does the same thing This leads me to believe one of three things:
A) the tolerances of the camera aren't great, and my sensor and lens mount are too close together
B) I just so happen to have two adapters that are off by approximately the same value
C) There is something more to the idea that the AA filter or microlenses are further than normal away from the sensor, and that is causing the variation. See this thread: http://www.photoclubalpha.com/forum/...hp?f=49&t=4419
So, I was hoping that a few of you could throw on the various adapters you have for your NEX camera and do a manual focus zoom at infinity to see if yours is slightly off as well. That could help me narrow down the cause. Thanks!
