I've been trying in vain to obtain a tripod collar for my EF70-200L f/4. I know this lens uses the same tripod collar as the EF400 f/5.6L lens but every dealer I've asked admit that it's a difficult-to-find item. Can anyone tell me the part number and its cost so that I can place an order with Canon? Thank you very much.
