(Leica) EPIS 400mm 1:4
#10
Thanks arv, I the lens indeed came for a machine like that (but different manufacturer). It is nice to see the lens element configuration in that brochure.

 

The lens is not designed to be sharp for an APS-C size sensor area, but instead for A5 to A4 size. The results I have gotten wide open are very soft. When I "close it down" by adding an aperture in front and behind the lens, the image improves considerably, I tried with an f7 aperture.

 

But the lens will be huge, and for an f8 lens or something that makes little sense. So, for now I will first pursue the scanner camera path, as this lens will be great for that application..

 

Here is an image of the test configuration I made, which gives you a little bit of an idea what a big lens it would be:
