I recently purchased a Konica UC-Hexanon 35/2 on RFF. I have had some issues with the focus on my M8. Below is the description of this issue.
At close-up distance, wide open (f/2) setting, the lens has obvious front focus. Front focus disappears and images are sharp when stopping down to f/2.8 and further.
At mid-range and infinity, wide open (f/2) focus is spot on and image is sharp. But when stopping down to f/4, the image becomes a bit softer (I believe it's a focus shift)
The rangefinder on my M8 works fine. My other 35mm lenses take sharp images on my M8 from close-up to infinity at any aperture.
I am wondering if the issue I have with this Konica UC-Hexanon is due to the design of this lens (which happens to all UC-Hexanon) or if the lens needs service.
Thank you
