Canon telephoto tripod mount collar ring size

I've been thinking about purchasing either a 70-200mm f4L IS USM or a 70-300mm f4-5.6L IS USM second hand (my mind leans more toward the 70-300 though). They both didn't come with a tripod mount collar ring from the factory, but I've seen one 70-300 in the ad with it bundled in. I'm now still saving up and afraid when I have the money that one with the collar ring will already be sold, so just in case, what’s the collar ring mount diameter for either of them?

Re: Canon telephoto tripod mount collar ring size

Internal diameter is not all that matters. The collars may have different width, internal surface shape (flat ot conical), edges, and even rims inside. You will need to buy a collar that matches the lens you bought.
