Not to resurrect another old thread, but I had no luck making chart tape or Letraset tape stick to my camera. In fact, I put some stickyback Velcro on the side to hang my remote start switch on and it's coming loose...
I do have a focus hook on each side and that seems to be a good enough visual cue for the ACs as well, when using the steel tape "freehand". Obviously the cloth tape goes on the hook. I still may bust out the Dremel and a straightedge and make my own film plane mark.
I think the Red One is very comparable to a lightweight 35mm setup (think 235) or a tricked-out 416 or HD camera (in fact it might be lighter than a Sony 900)
No complaints about the weight here.
