Mamiya Universal Press etc

[bythesea]

A few questions I've been mulling over.....

Why would I want to use the back spacers rather than the extension tubes? Is it purely because some lenses are not supposed to be used with the tubes?

The Vertical M Adapter - what is it for? The box says RB67, why would I want to use Press backs with an RB? Can an RB cover 6x9?

Does anyone know approx when the Universal & Polaroid 600 SE ceased production? I am guessing the 600 SE is much later?

1) Yes. Some lenses won't FIT on the tubes.
2) It's to take pictures in a "portrait" mode instead of landscape. Usually fits the back of the RB because the RB normally has a rotating back. The RB will cover 6x8, almost.
3) 600SE made it into the 90's.
