One problem I had, on both my A7r bodies, is that it would occasionally not focus and not recognize the lens attached. Out of the blue, it would just go weird this way. Turning the camera off and back on fixed the problem, but sure slowed me down when it happened. Have any you seen this?
The FE24-70 was absolutely invaluable for this work, especially for the closeups of the turkey. The turkey was very curious and friendly, and followed me around for awhile. But he moved cash and so fast AF and OSS were essential. One example is attached. You can see the other 33 from yesterday on my site here, starting with the last image on that page:

I've come to really love this lens, for subject matter like this. But I will use primes instead on my upcoming trip to Iceland.
