[Leica] So, wouldn't a 50mm Summicron LTM or 35mm f2 ASPH LTM be the best enlarging lens on earth?

[images at comporium.net (Tina Manley)]

Peter Krogh told me that I should not use an enlarging lens on the Beseler
slide duplicator when making in-camera dupes because it is flat-field.  Not
sure why but I'm now using the Leica Macro 100 and it gives good results,
better than the enlarging lens (Rodenstock) that I tried first.
