I got a Mamiya M645 a couple of weeks ago and thought I’d go look for a 80mm lens for it. Instead I found a Mamiya 645 super with 12 lenses, motor drive, a bunch of film backs, and a few other bits and pieces. All for a pretty decent price. One of the lenses (80mm f4 macro) has sticky shutters, and I’m wondering if they are hard to clean? Or expensive if I should have someone else do it?

12 lenses!

I guess you mean sticky aperture blades? I cleaned a 80mm f2.8 a few years ago. Not too hard. There are a few tutorials on youtube.

Watch out for the rear doublet on the 80mm f/4, the cement can degrade, leaving a hazy film between the elements. Same for the 80mm f/1.9.

With the 645 Super, be cautious about using the motor winder.
The biggest two differences between the 645 Super and the 645 Pro that replaced it are:
1) the 645 Super was susceptible to wear in the winding mechanism if used heavily - particularly with a motor winder; and
2) the 645 Pro added a self timer, but deleted the single manual "battery not required" shutter speed.
Some of the accessories are compatible with both, but there are a couple things like grip connectors that are model specific.
I started with the Super, added a 645 Pro to give myself a dual-body capacity, and eventually sold the Super.

You certainly have the lens situation covered! Nice score!

Depending on how the sticky aperture behaves (not shutter, Mamiya 645 lenses don't have shutters), you may be able to make do with using it in stop down, manual aperture mode - set the switch on the lens to "M" rather than "A".

Put the macro lens aside and enjoy your treasure. When you have time see about the macro. There are people who work on these things.

Unless some of those lenses are the relatively special purpose leaf shutter equipped lenses.
What 12 lenses are they, by the way?
I only have 5.

Yes, that’s what I get for writing stuff at 1am.

Yes, it still works stopped down as long as I remember to manually open the aperture between shots.

They are:
35mm f3.5
45mm f2.8
55mm f2.8
80mm f1.9
80mm f2.8
80mm f4.0
150mm f2.8
210mm f4
300mm f5.6 ULD

And three zoom lenses:
55-110 f4.5
75-150 f4.5
105-210 f4.5 ULD

The 35mm has broken rabbit ears (light meter coupler), but since I have two 45’s, one of which has sticky aperture blades, I plan to transplant those over to the 35. It requires some modification since the ones on the 35 are molded plastic, while the ones on the 45 are screwed metal.

That must be just about every lens made for this camera! Although there were different versions made of the same lens, such as "C" and "N" versions (I believe the main difference is in the lens coatings, with "N" being the later version). It's a great system, enjoy it!

Not quite, but probably most focal lengths.

I was able to 3D-print a meter coupler for my M645 lens. You can find my model on thingiverse.

Great advice, thank you!
