Tripod mount for EF 100 f/2.8, Macro USM, MP-E65 f/2.8, EF 180 f/3.5L Macro USM Lens only. Includes dedicated Tripod collar adapter.

Took me about 4 tries to get it on the lens proper, it fits and works very good.

fits good

ordered this used replacement ring and it was a perfect replacement. had tried a non-OEM brand that was awful, the geniune Canon works great.

perfect fit

This tripod macro ring 'B' works well with the appropriate lenses but it does not fit the 100 mm f2.8 L IS lens, it's too big.  The proper ring is the Tripod Macro Ring 'D'. Don't make the same mistake I did and believe the recommendations or you too will have an extra ring.

Ring B Doesn't Fit EF 100 f2.8 L IS

excellent

The tripod foot faces the lens front.  Locate the 4 Closed grooves on the mounting area of the lens barrel.  Mark these 4 Closed grooves on the side of the lens barrel towards the lens/camera mount with pencil.  Note the 4 splines in side shim ring- to fit closed grooves on lens barrel - align these so that the shim gap is at 9:00 (red dot on ring), when looking at front of lens and shim will snap into place.  The 4 bayonet pins on shim ring go towards the lens front, they must ALL ALIGN with the 4 notches in the T ring.  Carefully  align and insert the 4 bayonet pins into the 4 notches of T ring. (you must rotate lens/shim assembly until all pins align- only 1 position out of 4 will match up properly)  Carefully press the assemblies together and you will have a smoothly rotating assembly.  Rotate lens in T ring  to suit camera orientation lock and shoot.

Missing Instruction Sheet

I use this with a macro lens on focusing rails with a tripod. The ease to switch to vertical is a real plus.

Better than expected

poor design makes this difficult to use especially when in a hurry to change positioning on a tripod. The ring is not locked onto the lense and is very stiff to rotate and often falls out of the housing

design issue

I love len's with rings. As an avid tripod user, it allows me to switch from vertical to horizontal images with a minimum of pain. When I receintly bought the Canon Macro Lens [...], I also ordered the ring [...]. The ring does not turn smoothly as the rings on my other Canon and Sigma lenes do. I think plastic is great when used properly. It does not fit this application as used. Advice from a retired product development engineer. If you want a short Macro, try some other manufacturer. In most cases I have gone back to my old 180 Macro. Its a pleasure to use and keeps me out of the flower beds.
