negative:
1. Canon cameras with battery grip (fix as EOS 1D, or subsequently mounted as EOS 5D) can be fixed not directly to the bracket, as connection to the camera is not centered (would altnernative prolonged fast disk lock)
But meaningful way says yes, the word already from "telephoto lens holder" and not camera mount !!
RESUMEE: favorable variant to the more expensive products when you can do without luxury finishes
