I used it myself with an EOS 60 D - tip top; had EF-S 17-55mm lens (11.1 cm length) on it - fitted great would even tolerate about 1 cm more. Tip: don't use too wide an angle, otherwise the housing frame will be on the picture - but otherwise I took great pictures. Always follow the manufacturer's instructions exactly so that the whole thing is tight, then it's a real pleasure. Have fun
