That won't work. M42 yes, but Nikon F to PK adapters have to contain optics to be able to reach infinity focus. You don't want that. Same for Sony A, as it's flange distance is less than Pentax K.

Thanks for pointing that out. That’s only a nice to have - all my important lenses (zeiss primes) will be nikon mount zf.2s but I am mainly shooting them on my S1R. As my subjects are rarely more than 3 metres away, I wonder if i would get away with using a dumb adapter with the zeiss primes.

I'm not aware of really thin dumb adapters, just a rather thick one sold as "Macro adapter" (truth in advertising, for once). If you can find a reasonably thin one, I think it should work at least for the 85.

On the subject of ZF.2, I do hope you get the 135. The 50 (assuming it's the 1.4 and not the Macro) and 85 you own were redesigned for the Milvus line, and with good reason. The 135 APO-Sonnar is in a different league.

Thanks for responding. Before i bought the 85, I did compare it to the milvus using my flickr wall of pictures test and I preferred the rendering of the classic notwithstanding the better sharpness, less aberrations and better cross frame performance (if i recall correctly from reading this comparison) of the milvus. Ditto for the 50.

Regarding the 135, I agree completely.
