I'm at the lookout for a L-bracket for my EOS600D camera. I currently have a Markins Q3 Traveller ball head with quick release lever. At the Markins site, I cannot find a l-bracket for EOS600D, just a plate. However, do the Markins Universal L-Bracket LU-100 fit my EOS600D? Or are there any other third party manufacturers which have an L-bracket for EOS600D which fits my ball head?
