Originally posted by Optical Illusion Now that I've tried the lens, I'm not sure that it's all that "macro"... which was kind of my main reason for getting one... I compared it to the 18-55mm kit lens and it doesn't seem to have too much of an advantage over that one... That's just my initial impression.
Glad to hear that you found a "fix" for the potential problem. My experience with the 24mm is that it's really just a close-focus, 1:4 "macro" like most of the lenses that claim macro capability. FWIW, I don't recall ever seeing a true macro 28mm, but others might.
Still, I think you'll find that it's a fantastic lens that holds its own with the Pentaxes and Vivitar Close Focuses, although a bit more susceptible to flare when shooting into a strong light source--so I strongly recommend using a hood. I often choose my Super-Wide II precisely for the pleasing flare it produces, in fact. I've long thought seriously about picking up a copy of your 28mm, but never have for whatever reason.
