I shoot a good number of football games in a variety of stadium photographer's booths that were not designed by a photographer! My problem is I shoot with an XL2 and need my tripod and it is not always practical because of the booth size/design. I need to get the lens further out of the booth to avoid filming the sides of the frame on corner end zone shots. ( yes, I have hung the front legs of the tripod out of the booth, I don't care for that technique, dosen't work well and is scratching up my tripod) I have seen a rail type camera mount that can be clamped onto the front wooden frame of the booth or a rail, but I can't remember where. Can anyone help me? Thanks!
