Nikon 24mm F2 Ai - decentering?
Long time no post. I have a Nikon 24mm that I had been using up until recently when some of my results came out a little... fuzzy.
I usually shoot this lens wide open at F2 or stop down to F2.8.
At F2, the lens exhibits a blur effect on the left and right edges of the frame. Almost like the "instagram" circular blur (where only the center portion is in focus). This is great if it's what I want but ... it's not.
The thing is, at F2.8, most of the effect is gone except for the left side where a bit of the image turns to a blurry mess.
Image attached for reference. I'm thinking this isn't normal for this lens?
