Originally posted by tim60 Sharpness at infinity. I noticed the same with mine. In one way it is good to know mine is not the only one.
It seems the 28 and perhaps the 24 are best with subjects in the near or middle distance. This is a shot from the last time I used the lens in southern Colorado about 3 or 4 years ago. It had a humongous lens flare on it that I worked hard and long to eliminate. I can still see evidence of it, but I know it was there. The photo was taken at minimum focusing distance and at maximum aperture (or close to it).
I tried the other copy of the 28 this morning and it does seem a little sharper.
