I have a Seikanon 28-80mm lens with a macro ring, and I loved it until it started being a POS.
Basically, I can't get anything in focus with it (using the split screen focus thing for reference) unless I turn the macro ring a hair and then its fine. This happens even at infinity at focal distances way past anything that would constitute a "macro" shot.
Help?
Do I fix it or smash it with a hammer? How to fix it????? (I'm really that frustrated with it.)
The first thing I've got to ask, is have you tried any other lenses on the camera
The reason I've asked is because a focus problem is often in the body. I've known the mirror to become loose on someones K10D, causing focus problems.
I have no idea, how you can fix that. Perhaps just a screw that has become loose, which now allows the macro setting ring to creep? But I do not think it is worth a professional repair, unless it is a lens you value highly for any persoanl reason. I also do not think, that it is problem with the camera, but you can verify that with another lens.
