Having returned to 35mm digital photography, I am cleaning out some odds and ends. For sale is a minty Mamiya 3.5X loupe for viewing 645 and 6x6 film. It comes with both opaque and translucent extenders, the original box and case. Asking $195 net.
A little plug for these... I've got the 6x7 3X version of this and it is a stunning performer. Beautiful full-field view, no distortion and I can't imagine anything more sharp for this duty. Buy yourself a Christmas present!
