Depends what threads are on it, but there should be a way...

Most lenses for the Focomat will require a bit of an extension tube as the lenses need some extension from the neg stage to focus correctly... (Typically 1/4" to about an inch depending on lens...) There are old Leitz extension tubes floating around online auctions usually that are cheap...

Your lens might (or not) be E39, but there were extension adapters for E39 to the smaller 50mm old Componons that can be machined out to hold odd threads if needed...

First figure out the extension needed when you get the lens, and see what threads it has... There is usually different ways to get lucky with other than Focotar lenses... Different lenses can produce different effects for these enlargers...
