I recently acquired a lovely SMC K 17 f4 fisheye which works well on my K-1 (review to come) except it does not make it to infinity focus With the lens set on infinity, actual in focus point is about 6m away.
I'm planning to adjust this lens (have done so with a K 28 f3.5 with the same problem recently and it made a big difference to how it performed) and then had one of those moments... "what if something in my K-1 is out of spec?". So I whipped out my K-5 and K-01 and tested those to find:
- Can't reach infinity with K-5 (but not quite as bad as K-1)
- The K-01 is very close to infinity focus but still a tiny bit out
So clearly there is some variations in mount tolerances between cameras (as there is in lenses themselves) but most likely my K-1 is not the problem.
This is 3rd lens I have experienced problems with:
- Samyang 8mm fisheye - but then this lens is well known for this problem and relatively easy to adjust
- SMC K 28 f3.5. Definitely short of infinity on K-1 and is likely the reason why I was a little dissapointed with it on the K-5
- SMC K 17mm f4 fisheye as mentioned
So I'm assuming there must be other photographers using these older manual lenses that run in to these sort of problems - or have I just been a bit unlucky?
