Hey guys,
So i had the DA 15mm a month a half ago, but it came with a focusing ring being mis-aligned so I sent it back to Adorama. It finally came back in stock after black friday and they sent me a new copy. I was testing it today and I ran into some problems. For instance, I was testing if the corners were all consistent using a tripod/shutter release etc and this setup:
All the images are unedited straight from lightroom:
Here is the center at F4:
I personally think it looks fine, for wide open.
Here is the corner at F4:
Soft, but I think that as expected given the reviews of the lens.
Center at F10:
Very good!
Here is my issue! Corner at F10:
I feel like there is barely any improvement over F4!?!?!? And whats up with purple fringing? Am I doing something wrong here?
Like I said, I used a tripod and shutter release for no camera shake. The camera was not moved or anything between the two shots.
