I bought this camera to replace my Canon 5D 11, because I had a back injury and could no longer carry the heavier camera all day and because I had already tried the X10. But I am very disappointed in it. I find that it is almost impossible to hold it with touching one of the buttons on the back and changing the settings or the view. These buttons are far to sensitive.The focusing is remarkably slow. It has no stabilisation which I find remarkable since both the X100 and the X10 do.The above all make it a very disappointing camera for me, the image quality is very good but I think it should be used on a tripod as it needs very gentle handling and is too slow for anything like street photography.
