Just an idea. Last fall I picked up a nearly new, or new, Sigma 10-20mm lens. While I am no expert I can tell that the color and sharpness is equal or better than my Canon L glass lens. I have used it in a lot of situations, including the confined interior spaces of a battleship. It works, period. Little issue with distortition, even when I tried photographing a rifle with it.
Could be a much less costly alternative to expensive Canon lens.

Nice lens, but the OP is using 5D3.
