You have camera issues by the sounds of it. The camera is pretty bad in doors in low light, but otherwise it is pretty darn good. Should not have much out of focus unless you are moving and if you prefocus, it should take a picture pretty quickly when you full press it. The delays until the next picture can somewhat be helped by some apps in the market. BB Storm camera was not that good....really. The video on this phone should also be very good for you...double check your settings.
I will say that the low light images bug me and I wish they would tweak on this. Daylight pictures are outstanding. I also use 3rd party apps for my pict taking so I can take pictures pretty quickly.
