Can anyone help me out here please? What is this bracket they are talking about on the Nikon 70-200 2.8? And do you think this is a good deal. I was trying to find the Sigma 70-200 2.8 but can only find the macro version. Anyone know who is carrying the non-macro version? Without Bracket: $739 with excellent rating 1986 Nikon 80-200 2.8 Ed Afd Lens W/o Bracket With Bracket: $849 with very good rating 1986G Nikon 80-200 2.8 Ed Af-d W/bracket *77 Thanks for the help!!
