In a few weeks, I am shooting a dance competition for the first time (in my youth I was a lighting designer ballet and 'modern' dance) for one of my clients. I have shot concerts, fashion, events, airplanes, cars, soccer and swimming but not modern dance. Camera settings wise, I know where I start. What I asking about is lens choice or the possibility of renting an all in one. My kit consists of a Canon 6d, Tokina 16-28, a 70-200 (non IS) 2.8, a 35, 50, 85 & 100.

As I understand so far, I will have access to the entire facility. I am guessing the furthest sight line from the back wall to stage is 60' (based on the lighting plot). I am not that interested in carrying around a bag full of lenses for the entire event (8 hours). I do have access to a Canon T2i that I could use in a pinch. When I have photographed concerts, I carry a 35 & 70-200, and that is sufficient most of the time.

Given that I am likely to be shooting at the back wall and back stage, I am thinking of renting the Canon 28-300L lens for the show, or would another lens be better? Also, based on my information, flash isn't allowed.

Any recommendations would be welcome. Thank you much!
