I think a few FMers use this combo. I have enjoyed the Mirex but looking for more movement. Did see a "manual" bellows at KEH for about 300 USD in EX+ condition, but it was gone in a flash. I mostly see the "auto " versions
on yabe. Wonder if the manual one has more movments. Not really sure if there are any other differences to watch for.
Thanks for any comments.
The Mamiya Auto Bellows N is the one to look for. Auto simply refers to auto-aperture control, not autofocus. Here's what it looks like. The Auto Bellows N provides more movements than the Mirex alone, but you can combine them. The Auto Bellows N doesn't give infinity focus for most lenses; however, I have a couple of 6x9 lenses that do get infinity focus. I've also provided some data on movements and bellows extension.
Here's some figures showing magnification vs. bellows extension for some of the lenses I use, and magnification vs. working distance, which is clearance from the subject to the front of the lens (not considering a hood).
There's an Auto Bellows N listed on eBay now as item 110610049592. I don't have any experience with this seller. The price is less than I paid for mine.
The "adapter to connect body" mentioned in the eBay description and shown laying on the table in the first eBay photo is required to attach it to a Mamiya 645 body. You attach the M645 to EOS adapter (Mirex or fixed) to this adapter. I normally use the adapter as shown in this auction, and on my second photo above. You may notice that I've removed some of the gizmos from mine. I also have a homemade slim bellows to M645 adapter that I use to minimize sensor to lens distance (it's mentioned in the tabular data on bellows extension).
Couldn't ask for a more thorough answer. Thanks. I assume the front end wil take the Mamiya 80 +120 macro lenses too. I have a custom OM-Mamiya as to put my OM macros on the front. This will be a fun project.
I have the same set-up pictured above (mirex, autobellows N, 5dmk2) but found I really didn't use the auto bellows much at all. However, with live view, very easy to focus and a good range of movements.
