I know nothing of this from personal experience but have read that it is considered one of the best enlarging lenses available for certain ranges of magnification. I don't imagine it will be of much use to most people. Some have adapted this kind of lens (60/4 S-Orthoplanar for eg.) for macro use, but it looks like a difficult procedure and unfriendly in usage anyway. However, let me warn you that this lens is worth a lot of money. Do a search on the bay and find out for yourself.
