Title: Bad "hot-spot" and no-light
Review: Previous owner of the Canon-A85 & Canon-housing, I upgraded to the Canon-A640 & Canon-housing. Being exited about the new 1cm macro feature, I was soon to be disappointed about the "hot-spot" and no-light as called in underwater photography. The housing casts a shadow over just about half the picture when doing very close macro shots. Even 'upping' the flash-power, does not help, it only manages to create a 'hot-spot' in the left top section of the photograph. What happens is that the lens is encapsulated in a black section within the housing. The flash can not reach the section lying in the shadow of the lens. Previous models probably did not have this problem, because it does not have such a short macro focal lenght. Certainly a huge design flaw from Canon!
