Case in point. While I am anxiously awiting my UK Germany housing for my Canon 10D, I am trying to get some wide angle lenses together. I am thinking of getting the Sigma 15mm 2.8 fisheye lens but will it work? I have asked Uwe at UK germany but he is not sure. The larger dome port that I have ordered is known to be compatable with the Canon 20mm USM and the Sigma 14mm 2.8 EX HSM but there is no info on the fisheye. The physical size and specs are very close to the Canon 20mm : Lenght 2.9 vs 3.1 inches, closest focussing 5.9 vs 9.6 inches ( ie even closer than the 20mm) So I would hope that it will work


Any ideas?
