I've found that on my Ikelite system (Cannon F1, old style), the film advance, aperture & focusing knobs on the housing work fine well-past 60m- the big problem is the shutter release knob gets out of alignment with the button on the camera due to distortion of the housing (as you mentioned). I've solved this with a 5/8" diameter disk which screws into the cable-release threads on the camera shutter-release button. The large disk allows the Ikelite knob to take a picture at almost any depth. Of course, if you have an automatic camera, this suggestion probably won't help. Ialso have a problem with the focusing knob on my 100mm lens port at depths below about 55m, which I haven't yet been able to solve. As for pressurizing the housing, I think it would be cheaper to buy an aluminum housing....maybe not(?) Aloha, Rich
