used with my 60D coupled with a 15-85. ocean dive up to 5 meters and no leakage problems. laccès the trigger is easy, which is not the case of the target through the diving mask and cover the window; but even when you get there. 2 Access to the lens is not used much, at least in my case (it is very difficult to zoom). Compared to its purchase price, this case fulfilled its role and allowed me to take pictures underwater with my SLR with very satisfactory results. the front glass of the case deserved to be glass, not hard plastic.
