Re: A thinner sensor stack may be possible after all!

Nico,
How sure are you that your adapters isn\'t too thin? The Z* 21 f/2.8 seems to under perform when the sensor is too thin (i.e., when the lens is too close to the sensor). Non-floating element lenses like the Olympus OM 24 f/2.8 and the Zeiss C/Y 28 f/2.8 aren\'t nearly as affected by a thin sensor. In this case i suppose the conversion might have brought the sensor a smudge too close and that is affecting the 21 (which is very sensitive to this issue) and not the OM 24 or Zeiss 28.
Hello Spencer
That is a very good point actually and that may explain the problem if the Zeiss 21ZF lens indeed has a floating element. After the modification the Zeiss reaches infinity at around the 1.5meter mark.
Have just temporarily shimmed my adaptor and the Zeiss now reaches infinity at the intended point and it performs perfectly again
Thanks for your quick thinking on this one!
