Thanks JA - I may be pairing this with a 1” sensor so if it’s sharp at full frame, then I’ll definitely be good at 1”.
The only issue I see is that I’ll eventually run out of widefield targets - we do have a fair share of beautiful widefield targets, but what happens when I capture all of them? Maybe someone who uses this lens could chime in as to what they shoot? Most of the threads I see online are from the northern hemisphere, where they have the Sadr and Cygnus region.
