I "helped" a friend with limited budget find a fine used 300mm f/2.8. It arrived without the tripod collar and I've searched until my fingers are sore - no luck finding a replacement part.

Seeking suggestions. Posting on the buy/sell forum too.

You could try https://uscamera.com/ or any camera repair facility looking for a used collar. I suspect that with covid, a few have folded, so this might be a difficult find. I don't know if you can pull one off another lens and adapt one to fit an old 300?

Sorry, I just checked and it didn't score a hit. The part # is: YG9-0618 and it is unlikely you'll find one easily. I think you might want to look for a lens of similar dimension and try to find a collar which might fit? Another possibility is to reach out to: http://www.hejnarphotostore.com/default.asp. He machines a variety of replacement feet and other parts for lenses though I don't believe he offers tripod rings? I can vouch for the quality of his components and perhaps he can craft something for you? Alternatively, you could reach out to Kirk enterprises? They make some tripod rings though I don't believe they have one for the 300 f/2.8. Best of luck.

I got one of those (early, non-IS version), and it had the collar, but not the tripod foot. I found this extremely difficult to find, as that earlier model's foot was quite different than the later 300 f/2.8s. I eventually got it sorted, and in the process came into possession of a later model's foot that didn't work for me. So if anyone is looking for a foot, lemme know. I have an extra and am willing to give to a good home. -tig

You could try asking Hejnar if he could machine the ring.

I was just going to say that, have a friend or a machine shop make one.

How bout these ?

Some look a little wimpy for that lens but maybe buy a few parts here and there and make one.

Here's a wild and crazy idea. Even though this lens is no longer supported by Canon I would give the Canon Parts Order Desk a call at (866) 481-2569 anyway, unless you already tried, and see if by chance they still have one hanging around in their stock somewhere. I see that there is also a lower level parts list for the 14 part numbers with quantities that it is comprised of that may be a longshot if all are still in stock.

Search "Canon EF 300mm f2.8L IS parts catalog".

Hey, nothing ventured nothing gained.

That's 'another' part number for it.

While you are searching, I'd measure the lens.
Diameter and width.
Good chance there's another collar that would fit, or fit with a sleeve.

I didn’t think that lens had a removable collar but I found a photo of one on ebay.

After seeing this thread, thought I'd chime in to give anyone looking for a solution for a long gone discontinued part.

I found this adapter from Amazon https://amzn.to/42rJlcP

It's not a perfect fit as the inner diameter of this is 87mm, the outer diameter of the collar mount is 88mm. With a little dremel magic on the collar i was able to push it past through the 4 screws in the collar mount. Might need to use a pry bar to open the collar up just enough so you could slide it through. A few dabs of oil/lubricant will ease the process. Overall it's rock solid and the best thing is it's already Arca mount.

Note, the lens is already scratched up before i installed the ring.

Hope this helps!
