A Niggle

I used the Pentax a lot over the Christmas period, indoors and out. Outdoors it was round my neck, dangling against a thick coat when not in use. I found it is very easy when the camera is carried in this way for the rear thumbwheel to brush against one's clothing and alter settings, in my case exposure compensation. The wheel appears to be "live" all the time and not just activated via the shutter button, as on the Canon. Lesson: always check the setting in the viewfinder when taking a shot - but it's too easy to forget!
