Distortion is not a bad thing in photography; you just need to be aware it is happening and compose strong images working with the distortion. My underwater camera housing is set up to use my old Nikon D7000 camera body along with a fisheye 10-17mm lens. I made this image at 11mm knowing it would be greatly distorted, but I really liked the end result. D7000, F8 at 1/1000, ISO 800, 10-17mm lens at 11mm
