M42 Lens Porblem...

16 October 2007 - 09:02 PM

Hi, I have a Zeis tessar 2.8/50mm Jena DDR lens mounted on a Pentax spotmatic. There are two problems - 1) I cannot get infinity focus, and there appears to be a tight spot when screwing on or unscrewing the lens.
Any help much appreciated.

M42 Lenses ..... Which Camera To Match?

06 October 2007 - 05:20 PM

Hello all.

Actually have two topics here.

I have a Zeiss jena DDr 2.8/50mm and a Zeiss Jena DDR 1.8/50mm Pancolar both with M42 thread. One of the sellers of the lens also sells an adapter to fit EOS. I cannot get infinity focus on either lens with this adapter, and when set to infinity with the Pancolar, the mirror hits the back of the lens (as I suspected)
Does anyone have experience of this problem, particularly the lack of infinity focus? Comments much appreciated.

As (I'm told) these are good lenses, which is the best Pentax model (or others) that would suit. I'm a bit shy of trying anything that these lenses were NOT made for after the disappointment of the Canon. Comments much appreciated.
