printing larger negs on Meopta Axomat 5 enlarger?

[chris64]

Recently I bought a second hand Meopta Axomat 5 Color 3 enlarger which is working great and giving clear B&W prints from 35mm negs. However I have some 120 negs and some 85mmx55mm negs I would also like to print and am wondering whether I need to change the lens on the projector and also the negative carriers. The current lens is S2.8/50. Does anyone know what lens I'd have to change to and where I could find suitable negative carriers and the lenses at affordable prices?

I'm sorry, but the Meopta Axomat 5 is only for 35mm and smaller. But a decent 6x6 enlarger shouldn't be hard to find for a good price these days.
