Well looks like now is a better time than ever to consider an upgrade.. the top scroll wheel appears to be broken. It scrolls but it doesn't click in either direction which means it doesn't function at all
Not totally sure how this has happened but has had a fair amount of use (100k+ clicks).
I'm debating getting it repaired but at the same time a 7d is looking awfully tempting right now (around 700 used on TP seems like a bargain!)... has anyone had any experience of this issue before on the 40D, will I notice a big difference up to the 7d?? I find the main thing that limits me is the ISO, everything else I have loved about this camera and has served me well
Thanks!
