Samples taken with Tokina 300/2.8 - anybody has them?

Mine MZ5N also works perfectly with KA, KAF, KAF2 etc lenses but it sucks with srew mount m42 lenses - that is what I said! I wonder if this problem can be related to the mechanical aperture coupling with the K-adapter? Surely it can! I own original Pentax m42_to_K mount adaptor. I

Hi to everyone, I can't believe it and I am very surprised - I just made today many tests with bracketing and manual exposure correction with my Pentax MZ-5N, Takumar SMC 300/4 lens and m42/K adaptor (original Pentax adaptor, made in Japan). The tests show me clearily that I MUST manually and

Hi, My result shows that the AF sensors of my MZ-S in average locked focus at about 5-10mm in front of the target plate. The result agrees quite well with the similar testing carried out in the Dec 02 issue of CAPA Magazine, using MZ-S and FA*85/1.4 lens. Is it due to the problem of my
