Love the photos in this thread. I purchased a 28/1.8 to go with my 5D recently. I love it except for one thing. At 1.8, when focused on something more than say a meter or so away, it seems really soft and "glows" in more high contrast situations. It sharpens up and loses the glow when stopped down (very nice by 2.8. I may go back and test the intermediate apertures between 1.8 and 2.8, to see where it cleans up). It also seems to do fine at 1.8 if focused on something more like a meter away, but further away and it seems pretty soft.
Is that par for the course for this lens? I'm not shooting landscapes at 1.8, lol, and I mainly do people shots in context, so otherwise the lens is fine for me. If this is how this lens behaves, then I'm fine. I just want to confirm I don't have a lens with an issue.
