Hi there. I am a entusiast pentax forums, I read a lot of this forum, and I want to share with you a defect that I have with my old SMC Pentax-M 50mm F2 attached to my pentax k-5. I donīt know with is that. Can you tell me? There was a hard light at the right, but the defect is really heavy. Do you know why is that? The iso was a 1600, the exposure 1/100 and I think It was f8 or similar.
If you could help me, I would aprecciate.
The other thing that happens to me with this lens, is that I put it in f22, and the depth of field is like it was in f6 or 8, or similar, is low. Why can be that?
Thanks in advice. and sorry for my english.
Greetings.
Florencia.
