Gaston, what range of magnifications do you plan to work at?
Any lens can be focused close up. All that's needed is extension. Lenses that aren't perfectly symmetrical and are designed to be used at magnifications < 1:1 should be reversed when shooting above 1:1.
I've had a 100/6.3 Luminar, have a 100/6.3 Neupolar also have and prefer a 4"/5.6 Enlarging Pro Raptar for closeup work on 2x3. It isn't quite as good as the Neupolar but is easier to use. Ain't many lenses better than the 100 Neupolar. All expensive to put to use -- none in shutter, if you get one you'll have to buy a shutter and an adapter -- and the Neupolar and Enlarging Pro Raptar are hard to find.
I also have a 105/5.6 Schneider Comparon (tessar type enlarging lens) in Copal Press #0. It isn't bad and because it is in a #0 it can be reversed by swapping the cells front-to-rear. Interestingly, Schneider claims it is better than the equivalent Componon for low-magnification. Printing up to 6x, taking from 1:6 to 6:1.
