with 23/4. I am having a lot of fun with Capture One 12 now but had not been using Capture One for many years so I am trying to familiarize myself with it again. May be a bit too much manipulation of the image here
I have a feeling that 250/4 is really at its best at longer distance. At near minimum focusing distance, it is good
but not outstanding for some reason. From limited trial, I think Z7 with 70-200/2.8 @ F4 seem a bit sharper but
at longer distance, 250/4 really shines.

Thanks. Could you please demonstrate the above point. TIA.

The GF 250mm f4 is just as sharp at closer distances, but accurate focusing is critical because the the depth of field is so shallow.
This is a blue hour shot of Portland I took Monday morning.
I shot this with the 32-64 at 64mm, f/22, 120s, ISO400. I used f/22 trying to get the starbursts and slow down the shutter speed for the moving clouds. The starbursts at 100% have rings around the center light. You can see them in this close crop around the green light and the orange light in the upper right. I don't recall seeing this effect before but haven't done much shooting of blue hour city light shots.
Any idea what is causing this? Anything I can do to reduce the affect?
