I recently asked the question about sweet spots for Cameras and Enlarger on the
MF site. I received so very good information on camera lens and learned about
diffraction. My question is "are the problems the same with enlarger lens?"
Since the projection is on to a two dimensional field does this change the
quality of the print.
Is there an optiimum f-stop?
Thanks.

Yes. The better the lens, the earlier this will be attained. With the
better 50mm lenses, the optimum is about f/5,6-f/8.
