Dan, that is a point I had not considered, makes good sense. I will borrow a friend's Apo enlarging lens and see how that goes.
I have been producing exceptionally sharp colour RA4 and EP2 prints from negatives, for around 20 years with this lens.
I was of the understanding that this lens was, or should be alright for B&W. It could be though, that it has limitations with the latest VC papers.
I have produced quite stunning pictures over 15 years ago with this same lens, but that was single B&W graded paper.
I am learning a lot from this thread, makes life interesting, eh?
