Tripod Collar.

You're looking for the Canon Tripod Mount Ring B(w). Since the lenses that fits (70-200mm 2.8L / 2.8L IS / 2.8L IS II, 100-400mm, and IIRC 28-300mm) all come with one, they aren't sold separately by retailers. Your best bet is probably to call Canon service/parts, or post a WTB on fredmiranda.com.

Thanks

I can get you one, they have to be ordered directly from a Canon parts supplier. In Canada it's Global electronics. It's not a retail part.

I just bought 2 of them and they were $160 each.

Let me know, or call Canon in your country to get the part supplier.

In Canada the part is: YG9-0263-120

Do not buy the ebay ones, they have no metal insert in the screw hole.
