I've got a Sinar Handy and four lenses I use with it. All four are mounted on helical mounts....a 45mm, 65mm, 90mm and 120mm. I've just purchased an Ebony RW45E and lensboards and need lenses for it. One of the reasons I got the Ebony is so I can use some longer lenses and manage perspective. However, I want to know whether I can mount the wider lenses I've got (not the 45mm....it's only used to make the 6x12 panos on my Handy with it's centre filter) onto boards without taking them off the helical mounts. If I remove them, apparently they need to be factory refitted to the helical mounts if I want to use them with the Handy later on.

I just want to make sure I don't spend money unnecessarily by owning too many lenses. Unfortunately I'm flying a little blind.

Any helpful info would be very much appreciated. Cheers,

Craig
