After receiving it I noticed it is only intended to be used with "grand cameras" , like the EOS 1 series (film or digital) or to those other series cameras that already have a battery grip attached to them. Fortunately that's my case in which I always carry my 10D with its BG-ED3. I tell this since a 10D, 20D, DRebel or 350D body does not have a strap eyelet on its base. Only their compatible battery grip has it.
