Kempa, you've probably managed to highlight in a single paragraph the key differences between shooting with a DSLR and a digicam.
In the case of the 300D as used by Will (and other DSLRs), you don't have the option of using an LCD
to compose and shoot - the point of the SLR design being to look through the lens itself via the viewfinder. As far as metering goes, this is performed continously and instantaneously right up to the moment the shutter opens (unless of course you choose to lock the exposure) - this can be a real plus in continuous shooting, particularly with intermittent sun.
Again with AF
- as far as I know, all DSLRs have a servo mode which allows moving objects to be continuously tracked by the AF
system right up to the point of the shutter opening.
Certainly your comments are useful and valid for digicams - but do perhaps illustrate what DSLR users are paying for
