I love our S90, but from day one I had problems with the rear wheel. I accidentally changed my settings because the wheel would just turn too easily.
Lensmate now has an easy, yet practical solution for my problem and it is very cheap. I just installed this on my S90 and it works perfectly - no more unwanted changes to my settings - I am again in control of my camera
