Hi falconeye,
I'm contacting you to ask a question about the sigma 500/4 MF APO.
I have a copy of the same lens and i need to clean an element in the focus group.
My question is; Have you tried to disassemble yours? And if yes do you have any suggestion on how to do it. Thank you for you time.
Hi Falk, Good morning. I was in München at the end of March but I had no time to message you for a head meeting. My son is working in Würzburg for CareFusion, former Jaeger® Jaeger® - CareFusion
Whenever you come to Lisbon let me know for a meeting. The Pentax office in Lisbon has been closed and moved to Spain, so no more new bodies to discover.
Best regards,
Rui
Dear Falk, help me, please, with formula how to calculate lens resolution at K-5 (LW/PH 2750) if we know the lens resolution at K10D (max. 2350 LW/PH at photozone). I think it's not direct dependence - 2750 - 2350 = 400 LW/PH. Can you explain me how to do it?
Falk, thanks for all your great contributions to the forum and for living up to (and exceeding) all the high expectations we had, when we voted for you as a Pentax K-7 alpha tester. Your K-7 test reports are a great resource.
