We’ve just obtained our new Powershot S100 and can confirm that our existing 37mm Quick Change filter adapter works perfectly.
Though the focal length has been extended to 24mm on the wide end (from 28mm on the S95), there is still no vignetting whatsoever even with a full depth 37mm polarizer attached. A redesigned lens control ring on the S100 means the Lensmate Quick Change receiver now adds only 2mm to the total depth of the camera.
