Hi

I'm quite new at digital photography.
Until few weeks ago I used a canon powershot A10, so a very simple 
camera and a SRL from which I used to scan after.

I bought a powershot pro1 but I don't feel easy using it.
I'm not dissatisfied with the pitcure I take, but there is something 
missing.

Also it seems that, in composing the image, with the shutter button half 
press, the images freeze on the viewfinder/LCD monitor until all the 
reading are done.

Is it normal?

Could some of you help me? I read the reviews on dpreviews after I 
bought the camera. (shame on me)

Thanks
