Christian, I think the software and lens advances went hand in hand. There was no need for sophisticated lenses as long as the sensor was primitive. Hi Lou, yes this sounds logical. As far as we found out in this group, in all the industrial high-end scanners as the Israel-made Creo (finally Kodak)...

For what it's worth, the inexpensive, lightweight Minolta 35mm f/2.8 that I just tried had a working distance of 32mm. I'll go through my lens drawer, and just possibly find a hidden gem. :wink: Thats the WA 35mm I assume, not the 30mm enlarger lens? The enlarger lens had serious CA issues. @dmilla...

Hi Robert,

I would like to see Center/Center then corner/corner in one 2500px image.

And I am very exited about the results - especially the sharpness results of the 7,5x Mitu in this "grail" ;-)
Thankyou again for your great efforts - for all of us...!

I was going to reply that I had given up on stacking combos ... Which telephoto? ... The Sigma 150 macro would give me a little over 5x. Hi Robert, I believe you do not plan to use "relay"-lenses below 135mm - but -- IF a combo -- what about using the Nikon 100 mm Scanner Lens as a base? Are the 10...
