A Mamiya Lens...

This adapter is for M42 screw mount to Canon EOS. The seller is mentions Mamiya in the title by coincidence because Mamiya made M42 lenses. However your particular Mamiya lens may not be M42 mount as they also made lenses in other mounts. 80/2.8 sounds like a medium format lens. Do you know what kind of camera it went to?
 
Certainly looks like it will work, but I have no idea if the backfocus will be accurate. This isn't as big of a deal with a prime lens, so long as you aren't relying on your distance marks.

Edit: shaocaholica also brings up a solid point as well :)
 
If you guys don't mind can you post your experiences with this adapter or any others like it. I also have a 80 mm f1.9 i was sort of curious to see put on the 550d.

i have a "wide angle" 45 2.8... wonder what that would look like. i'd love to see some footy.

As far as FOV is concerned, your medium format 45/2.8 will look like any other 45mm lens. 45mm is only really wide on medium format. When you adapt it to 35mm full frame (5D) or APS-C(7D), you loose a lot of that FOV.

This is correct. just as an 80mm is almost a "normal" lens on a mid format but becomes like a kinda long SLR 80mm lens, same fov as a nikkor 80mm
 
ya, i understand that hence the quotations, however it'd still like to see the look of the lens on the 7D/t2i just to see how it renders colour/sharpness.

ooohhh... you'd loove it.. the mid format lens, when placed on a 35mm camera, renders brighter image than its 35 equivalent, also in the case of the mamiya, a warmer color palette which is, for me, more pleasant. It also has different contrast. Cant recall which is more contrasty though.

Did lots of comparison on it before since the first lens adapter i made for a video cam was for mid format lenses, later I made one thats a hybrid. Allowing me to use both 35 and mid format lens. Eventually, for purposes of convenience I switched totally to 35.

Now all thats a thing of the past since I placed my first lens adapter in a glass case in our photography museum since DSLRs rendered them obsolete.


p.s. gimme 3 hrs and I'll post a comparison for you. Between an 85mm f2 nikkor and a mamiya 80mm f1.9 on a 7D for you.

yeah, I'd like to see that if possible. So what exactly is the crop factor for an APS-C sensor and a 645 lens?
 
I've already ordered this adapter. As soon as I get it, I'll post some footage so you can have an idea how it works on the 7D.
 
I'd love to see some medium and large format glass footage too. I've read that medium format and large format lenses aren't designed to resolve as much detail density wise since the imaging area is so large but whatever, I'm more interested in the colors and tones than the sharpness. Hell, I find it distracting when moving images have too much detail.
 
cool, i look forward to seeing some examples. The lens is just sitting on my old 645 and doesn't get much use. I'd love to put it to use again. Plus i'm headed to japan this summer where you can find old 645 lenses for almost nothing.

yay!

The same as for a 35mm lens. 1.6x.

Thats not exactly what I meant. I was wondering what the method or calculation formula was to figure out what the "look" will be compared to the "full" 35mm film or sensor size comparison we are used to making. I figured it out. Actually because this is a 645 format lens an 80mm in my case is roughly double the 1.6 or a 3.2 "crop factor" to effectively make the lens appear like a focal length of 240-250mm mated to the APS-C sensor in the 7/550d's. Right?
