I've just noticed that the "D" type ring has a hinge on it in order to allow it to fit into a groove on the L version
the "B" type ring by canon & the generic one are one piece & would probably not expand enough to slip past the collar on the "L" lens
I can't even see where the ring might mount on a non "L" version , any ideas?
cheers

There are two flavors of tripod ring mounts for the Canon macro lenses.
Tripod Ring Mount B - 100mm f/2.8 Macro, MP-E 65mm 1-5x Macro, 180mm f/3.5L Macro
Tripod Ring Mount D - 100mm f/2.8L IS Macro
*note: the 100mm f/2.8 Macro requires a special adapter ring to work with the Tripod Ring Mount B. Something a lot of the generic eBay tripod mount rings dont come with.
*note: there are usually designators at the end of the Tripod Ring Mounts like (B) or (W), this is to indicate the color.
The Tripod Ring Mount D is of the type that has a hinge in the middle so it can open wide to fit its lens. You do not "slip" this type of tripod ring onto the lens like most are installed. You can see what Im talking about from the B&H (LINK
) image here:
Both tripod ring mounts can be used with a few other lenses, so they can do double duty, but the colors often wont match because some of the other lenses they work with are white. The Tripod Ring Mount B is compatible with more lenses I believe.
On a side note, there have been quite a few people who have had some troubles with the generic tripod ring mounts breaking, not tightening down enough, or just otherwise being made not of high quality. Personally when it comes to support gear I never go cheap or generic since the support gear (like tripod ring mounts) is what keeps my photography equipment safe and stable.
