Hi,
I recently acquired a Pentax SV with the Supertak 55mm f1.8 lens. It is my best looking / best feeling camera. I took it out for a spin and I'm noticing some focusing issues. Looking thru the viewfinder, "infinity" is about 15-20 feet away, but beyond that it is never in proper focus. I took this series of test shots and the only useable pictures are those at f16, maybe f11. Below that I'm not getting proper focus.
1/125 f16
1/250 f11
1/500 f8
1/1000 f5.6
I don't have equipment to test for accuracy, but the shutter speeds seem to be ok and consistent with other cameras. The lens is properly seated/installed.
This morning I took my Spotmatic and swapped the Helios 44 lens and the issue follows the lens. I can't get to focus to infinity in the Spot either. The Helios focuses fine in the SV. This was a viewfinder test. No actual shots were taken on film.
Could this be an adjustment issue on the lens? If so, how can I proceed? Both the lens and the body look pristine with no obvious signs of repairs.
I have some experience disassembling lenses if needed.
Can somebody point me in the right direction?
Thanks,
