If I measured accurately? What are you implying - that I measured it with a tape measure? OK< I did measure it with a tape measure, although the previous measurements were with a little stainless steel ruler. So, none of my measurements are going to be perfect. Now on to more imperfect measurements. I measure 3.25 inches from the back of the camera to the front of the AD mount - I thought this might equalize things a little for comparison between housings. The Canon housing does have the thick bezel around the front glass, but the back of the lens projects behind the back of the mounting plate so it is very close to the front of the glass. Another imperfect measurement suggests that the front of the camera lens when set at 28mm will be about 1/2 inch from the back of the INON lens. I suspect that the greatest difference between the Canon and FIX housings will be the double glass port (no fogging). I may make some similar measurements with my old Sony P150 and Sony housing and INON adaptor and see what I come up with as far as lens-to-lens distances go, but I have to go to work today and then off to New Orleans for Jazz Fest this weekend. Diving in Philippines in less than 2 weeks. Woo Hoo
