ok so last night i was shooting with the nifty 250 at my sisters prom. (only lens' i have at the moment are the 18-55 and 55-250...) it was a low light situation and was shooting from about 30-40ft away at grand march so my flash was worthless. a couple of the pics of the grand march came out blurry and i told my dad that the pics would have come out better if i had a better lens. to which he replies "you bought this expensive camera and still can't take decent pictures with it? you should have just put it on automatic and let the camera do the thinking for you" we go back and forth a bit i tell him i was shooting on aperature priority mode with the aperature wide open and ISO on 3200 (canon T1i). basically by the end of the conversation he told me to take my camera back because if i can't take the pics i want with the lens' i have then i don't know what i'm doing.
anyone care to help me out on this one?

. Tell him to pony up the dough for a 70-200 f/2.8 and you'll get the shots he expects.
