I'm starting a B&W darkroom with my recently acquired Leitz Focomat V35. However I would also like to be able to print from 645 and 6x6 medium format negatives. I have an opportunity to acquire an Opemus II enlarger with Meopta Belar 4.5/75 and 4.5/55 lenses. Would this be suitable for 645 and 6x6? Any good or bad points that I should be aware of?

I've found quite a bit of info about the Optima II a on the web, but little about the II. Does anyone know what the differences are?

Many thanks
