Thankyou for your comments Alex and Adam, Ive since learnt a few things about this camera, and aside from missing the pixels of its its bigger brothers, I would have to say its better than the 350D I had last in all other respects, the missing pixels are not really a big concern...I had considered that I was downgrading...but NO, I dont think so...Its a great little camera...
It dosnt bloom so readilly as the 350 did, the Live view is just great, and its incredibly light..the LCD window if used has large display,s of info I need and is easily dimmed or turned off, the menu system is easy to navigate in the dark..and it will run all night on the battery. So it must be more efficient, one might assume that this results in less heat from a dscharging battery warming the chassis... maybe,

...none the less Ive ordered n AC coupler... Very happy with it...
