The SS-1 will fit any front-lens digital compact with dimensions not exceeding 101mm x 65mm x 29mm, and which has an on/off button the the shutter button on the top panel. This includes around 70 percent of all compact cameras, and certainly the vast majority of recent compact and ultra-compact cameras up to about 5x zoom, although some models with very long zoom lenses may not fit, and Panasonics with slider switches are not suitable.
The secret to the SS-1's adaptability is a system of silicone rubber cushions which slot into positions on the inside of the case. It comes with a sheet of rectangular cushions ranging from 1mm to 10mm in height that fit in around the sides, top and bottom , as well as smaller round cushions that support the front of the camera, and a selection of self-adhesive foam cushions that support the back of the camera with a cut-out to allow the monitor to be viewed.
The rubber pads are re-usable, so that the case can be adapted to more than one camera, but the foam pads on the rear panel are pretty much impossible to remove without tearing them. However it does come with several of these pads, so if you change your camera you don't have to buy a new case. Even if you run out of the proper pads it would be fairly easy to improvise with some foam off-cuts and double-sided sticky tape.
The case comes with easy-to-follow instructions and a handy measuring diagram to help you select the correct set of cushions for your particular camera. The only tricky part of the installation is adjusting the positions of the two button linkages to activate the on/off button and the shutter button. These have a selection of different length actuator rods that have to be screwed into place and then carefully positioned using a tiny and quite fiddly spanner, which is supplied. However with a bit of trial and error this too didn't prove too difficult. The button linkages are quite loose, so cameras with very small controls may been a bit of persuasion to operate properly, but I was able to customise the case to fit my Casio EX-S12 ultra-compact in about 20 minutes.
