Yes, I am mounting it in the 35mm position. I also tried this:

1. turned the camera on without the lens on (worked normally).
2. mounted the lens while the camera was turned on. Viewfinder display stayed on, shutter speeds could be changed and were displayed properly. However, shutter button was inoperable (as was autofocus).
3. took the lens off and the camera functioned normally again.
