"... NO effect what so ever on images taken"

hilarious e*bay posting...

" The impressive Canon 50mm 1:1.2 lens is cosmetically incredibly-clean,
with smooth focusing and clean glass and no oil on aperture blades
because there are NO aperture blades to be found on this lens,
yes it's missing aperture blades and there is a small glass chip on the
very edge of rear element (see last image). I was told by previous owner
that this camera was used exclusively for available light photography
and small chip in the rear had NO effect what so ever on images taken"

the words "highly unusual" come to mind, lol.

Yea... it makes kind of sense... if there are no aperture blades, then there is no oil on the aperture blades... Sounds right...

Let me be the first to admit that I don't know. Perhaps the person that removed the blades put them in a jar of oil to keep them from rusting and set it on a shelf in his workshop. As I said before--I don't know!

it s meant to be shot wide open anyway, no big deal

 

[raytoei@gmail.com]

maybe without the blades, the canon 1.2 becomes a 1.0 ?
and everything becomes shutter speed controlled.
is that possible ?

 

[sparrow6224]

It's quite possible. See Maitani above. There are many people who say they shoot "only" wide open although this seems a very limited form of photography to me. Particularly as I dislike OOF material in the foreground, in front of the focal plane.

 

[maitani]

the above was a joke 😀

, i also don t think such a lens could be usable for anything, i agree although that completely free of blades it coud come close to a 1.1 or 1.0 lens

If someone is buying it as a dedicated low light lens the lack of aperture blades may not be an issue. I picked up a VC 1.1 specifically to shoot at night. I think I've only used it wide open so far. I'd use a less specialized lens if I wanted something for brighter situations.

Assuming this sells at a decent discount, it may be a good buy for a nighttime shooter.

It is hung on a very nice Nicca body, which may end up being worth the sale price by itself.

The chip is not overlarge. If a previous owner was not shooting into bright light, it's possible they still got good or very good images.

I love using my Zeiss 85/1.4 wide open. It has broken aperture blades, so it can only be used wide open. Else, it is very clean and without ant damages.

The canon 50mm 1,2 wide open has a raltivly small sweet spot in the middle of the frame and very soft corners. To get real good results you should at least use f 1,4.

For some reason Canon produced lenses with no apertures. I have a 200mm f3.5M for MB-2 that has not diaphragm. It has the aperture setting ring, the cocking ring and the release button, but nothing inside the lens. I have seen a few 50mm 1.2 lenses offered that did not have apertures. I don't know if these were special order for scientific use or for some other purpose.

Gee, I was thinking the previous owner removed the aperture blades, and chipped the rear element trying to get the damn thing back together. It's funnier that way.
