im just not getting the clarity out of my shots that im wanting, they seem to be missing the crispness. with my 18-55 kit lens the pictures just arent as crisp as with my 70-300. is it because its a kit lens? does the lens make THAT big of a difference? ok now i know the lighting isnt that great, i was stuck only having my flash and it was a VERY overcast day. but it just isnt as crisp as im wanting it... just not as clear... whats wrong?
