I've got the latest and greatest lenses to enlarge with (well, at least good modern ones), but am curious about the older classics. Is there any good reason to look to some older enlarging glass? Is there a signature or character that could be had, similar to working with older glass in camera lenses? I'm perfectly happy with my lenses now, I just wonder if I'm missing something good. Unfortunately, it isn't easy to mount a lot of the older lenses I've seen since they are heavy and need a larger hole than my lens boards provide. Obviously I could have them mounted, but it's not worth the effort if they aren't up to snuff.
