Hello all, i found something in my closet i no longer need. Its a L glass tripod collar. B(W) meant for the 70-200L 2.8IS. Its virtually brand new, and no scratches or anything. Very little scuffs on the bottom mount area. Canon doesnt sell this separately in White. It will fit 70-200 2.8IS, 100mm f/2.8 USM Macro, 180mm f/3.5L Macro, & MP-E 65mm f/2.8 Macro Lenses says BH Photo. http://www.bhphotovideo.com/c/product/194450-REG/Canon_9487A001_Tripod_Mount_Ring_B.html#features asking $100 shipped and paypalled. I no longer shoot Canon so i dont need this.
