Dewman, it is nice to see your comments and your fine example from the Sears 28mm Macro.
I just received a Sears 28mm f2.8 Macro, hoping it would be a nice copy as it was described by the seller. It was in very bad shape, so I got my money refunded, but we agreed I should keep the lens since it was worthless as it was. This lens was badly fogged. Someone had tried to clean some fungus, and left the aperture sticky and the glass coated with residue. One of the elements was reversed so it would not properly focus until I reversed the element. I was able to clean most, but not all, of the fog. Unfortunately, the fungus has etched along the edges of one element, but the lens is now functional. It would be nice to have a clean copy of this lens to see what it can REALLY do!
Some examples with it mounted on my K5:
