Hi, been meaning to post here for some time, I do hope my message gets read (this is a great resource for the GOOSE).
I have 3 diopters for my Polaroid, I recently purchased the Mamiya focusing hood. And more recently the necessary M adapter.
(I already have one film back and I have also ordered the film back model which will shoot, 6x4.5, 6x6 and 6x9, so I knew I needed to order the M adapter eventually).
I have also been watching some macro extension tubes on ebay. These appear to come in 5 sizes (so offer more variations than the 3 diopters).
My question is if I do invest in the macro tubes, is it absolutely necessary to also purchase the back spacer? I mean what would happen without that, would the image just appear blurry?
Thanks in advance.
