Checked on the K10 and SF-1. Seemed to work at first on the K10 but then couldn't lock on at infinity. Same for the SF-1. I tried adjusting focus on my K-7 but even at both extremes (-10, +10), it didn't make any difference so it would appear that the problem lies with the lens. Good that itisn't a camera problem but now I have to look for another lens.

Good question. I'm going to try the lens on a K10 and a 35mm SF-1 tomorrow and will be able to confirm where the problem lies. If the same on those, then the lens is probably toast.

I just recently acquired a used F70-210 for my K7. It seems to work well in most configurations but I'm having difficulty focusing at infinity when zoomed to 210. It seems as though it needs just a litle more on the focus ring and it would be ok but of course, it's at the maximum and sill not in focus. I know the previous owner and he used it on his 35mm with no issues. Has anyone else experienced anything like this or is there a problem with the lens?
