40-150 PRO focus breathing?

Re: Example image

I used the APS-C crop mode on my a7S, which simply crop's in 1.5 to Sony's APS-C sensor size.

Yes, you had made that clear. But I've never heard of focus breathing changing a lens' angle of view by some 50% as appears to be the case here. So, I wondered if there might be another explanation -- such as you inadvertently using digital zoom on your Sony, in addition to crop mode (if that's possible at all). Anyway, I'll take your reply as a  'No'.
