What happens if I were not to half press the shutter and just press full? Does the camera attempt to focus? Or does it have a preset focus calculations in it which it will use?
 

depends on the your camera make and model.
whether it will take a picture or not depends whether the camera is a shutter or focus priority. some models will not take a picture without focusing, others will.

the best way to ascertain this is to try!
 

Some cameras doesn't allow you to shoot without focus in AF mode.
 

those were the good days of our "idiot proof" 35mm p&s and the "old shool" SLRs!! the newer AF digital cams, SLRs, and DLSR usually employ some form of autofocus before capturing / triggering, unless you are able to bypass this with a manual (M) focus mode. short of which, normally an immediate full press on a AF camera would not lead to an immediate trigger, as the cam would attempt to focus (similar to that of a half-press) first before firing as soon a focus is achieved (else not at all).
 

Personally I don't think it really matters whether or not the camera focuses, cos you're very likely to get blurry pictures cos of handshake! (Unless your shutter speed is very high, ie 1/1000s or above.)

Its not really possible to "snatch" the shutter without inducing a considerable amount of movement.

what is 'snatch' the shutter? in my manual camera i am always clicking in this fashion and i do not get handshake.the same thing applies for manual mode in DSLR's. so even in a,s,p modes i believe the D70/s is shutter priority which means you can shoot even when camera is not in focus. the D50 which i have is focus priority which does not allow me to shoot if not in focus.
 

I think he means that the photos might turn out blurry because since there are two stops, pressing directly might cause a higher chance of camera shake. And thanks everybody for their reply.
