Dimka did you remove the rear element on 85 FD L? That's kind of like my 50mm f/1.2L FD without the rear element

I think he explained he did, to accommodate for the over-intruding of the lens into the girth of the Mamiya mount.

wiregen, as Leon has already said - i removed the last element, because if i leave it - the lens would not cover full 645 frame and the real problem to fix the last element in its position and need to cut mirror more and just for the information - i have another 85mm 1.2L without two rear elements - in that case it would cover 6x9

I have tried this combo (mamiya 645 +85L ) with original hood - thought it would be worse

I agree with an above comment. I don't see a sharpness plane for reference.

Interesting stuff! Removing 2 rear elements (the last 2?) covers 6x9? wild. I wonder how that would be mated up to say a Fuji 6x9 or something.

Thanks for taking the plunge on all these adventures and sharing the results with us.

all f1.2

bellyface, i do not have any other lens for that mamiya 645 afd, i just wanted to find out how will look really fast lens on such big sensor/film area.

Jim, few things to consider - not that easy to catch the right focus in the viewfinder (although i have screen for manual lenses Type C - it is really helpfull for center area focus point) and scanning procedure.

Ed, thanks for your words.

Just stumbled upon this thread, very beautiful (and strange!) shots here. I was wondering if the Sigma 50/1.4 could do something similar... from my (very) informal tests, the image circle is larger than my 85/1.8. Of course, I don't have anything to test it on, but a f1.4 WA on medium format sounds intriguing. I guess Canon never had their 50/1.0L in FD mount?

Personally I don't get it since the removal of the rear element has totally ruined the image quality. Cool idea, but I'm not impressed by anything other than the effort.

Kudos for trying it out!

Makten, thanks for your opinion, but few things to consider - it is impossible to leave the rear element with Mamiya body (but even if you manage to fit the rear element, the lens itself will not cover 645 format), many others fast lenses do not have that floating element and still produce great images wideopen, it could be that there is some focusing error - it would be great if i had digital back and could adjust focusing screen and the lens, see sample with flowers

it is also wideopen and focusing is quite in spot. When you stop down the lens it performs quite normal

Just to show the idea how much you need to modify your mirror and lens rear mount in order to obtain infinity focus

For my personal taste - I really love the images with that combination. Unique signature. The softness seems to work well with portrait subjects and the OOF area is just in a category by itself. IQ is one characteristic, uniqueness is another - creating a composition can be a combination of many different aspects.

I understand removing the last element to increase the light path for the larger sensor but would that lens work on the Mamiya with a Mirex or similar adapter to keep from getting into the mirror path?

, on the left is fd 85 1.2L converted to EOS mount on the right mamiya mount - it is obvious that the only way to put this lens on mamiya body is to put the new mount.

I don't get it either. Why dumb down a good lens?

Jim, i have got this lens without rear lens already and i have normal eos converted fd 85 1.2L and ssc asph 85 1.2, so why not to use this "half" good lens in other project. As i have showed before it is very good performer on Mamiya 645 AF/AFD body when you stop down by f2 -f4, so here is a question of sensor area and f stop, it is nice to have two different characters in one lens just changing f stop.

Yeah Dim.ka_

I was writing at the same time you posted that first one. Quite the surgery, that explains why all the shots are at f1.2.

Actually there are shots at f2-f4 as well, i have showed more f1.2 just because it is unusual to see such f stop on MF body.

If you stop down, what's the point? A 80/2.8 will yield a thousand times better results at f/2.8.
I really like the idea of f/1.2 on MF, but not if the image quality is like that from a Lens baby.

Edit: How about flipping the mirror up and use it with scale focusing, with the rearmost element in place?

While I salute your creative engineering I can't enjoy the pictures themselves. Most are not sharp even at these sizes and bokeh is, well, how shall I put it mildly? With a lot of character....

Happy shooting,
Yakim.
