Canon 50mm f/0.95: Looking for Parts :-)

[Dave_MB]

Howdy All,

If anyone has any of the mechanism for the Canon 50mm f/0.95 lens, my brother has this lens in what appears to be a TV format and would like to make it useable with his Canon DSLR EF mounts. Toss me a PM if you know where we can look or have anything to sell that could be useful and I'll put you in touch with him. Also, don't hesitate to post any info that would be useful in getting this lens restored. He has access to someone who can recoat the glass and I think he's got someone to rebuild it if he can get the missing parts. We're located in SoCal.

I was told that my photos might not show-up unless I put them in a reply, and sure enough, they didn't . Reposting the photos :- ). I think they will now show-up twice.

I'll presume that the TV lens is optically built similarly to the rangefinder version, therefore, with the same flange distance. If it's not, please ignore my words and correct me.

You won't be able to use the lens on a DSLR and keep normal focusing distances. The mirror box will separate the lens from the sensor just like an extension tube. You'll be able to focus in macro distances, but not on an usable distance for a portrait, for example. You'll adapt it easily on a mirrorless camera, though.

Thanks for the heads-up about the lens mounting. I'll pass that along to my brother. The best situation would be to locate someone with the "official" original Canon version of this lens but with damaged glass and wants to sell. At least my brother will be able to put together a working version to use with an old body that readily accepts that mount.

While finding a 50/.95 body would be the best option, you may never find one.
a temporary substitute would be prudent.
Some machining and assembly required... Assuming the back end isn't too big, what is the diameter?

Yeah, I'd rather you began to learn from the knowledgeable people here, Dave,
as I've no experience with C-mount/CINE lenses.

As a CINE lens, it's not so much the 'Holy Grail' your brother may have thought it is.
It'll take quite a bit of customizing to have it working as a standard lens on a Canon DSLR,
and doing so may be prohibitive in cost and/or aptitude.

Your brother will likely have far better luck in adapting it to a mirrorless-camera system,
as has already been mentioned.

Howdy All,

Well, it's not as bad a situation as I had posted . I misspoke when I said he wanted to make it work with his DSLR. He actually wants to make it work with a mirrorless camera mount. I'm going to have him read these posts (and maybe even get him to create a login and post himself!) Thanks for the feedback and links to eBay.

See Ya, Dave

"The Canon 50mm f / 0.95 was produced under a 3-blade RF mount, onto which, right at the time of release, an “s mount adapter” was screwed on to mount it on a Canon 7 camera.

This Canon 50 mm f / 0.95 lens was mass-produced with a cropped rear lens segment. The rear lens did not have a completely round cross-section, but had a lateral groove-notch in the place of which an internal diaphragm pusher-rod passed.

This is the difference between the Canon 50mm f / 0.95 lens and the Canon TV 50mm f / 0.95 lens, which has a round rear lens without cutouts and a factory-mounted RF-C-mount adapter."

Howdy Sergey,

Thanks for the additional details.

It's very interesting. I have the same one.
