just got my canon eros 400d to try learning tricks for digital photography...
anyone got any idea how to maintain the 400d? like how to prevent dust from smearing the lens, what kind of stuffs needed other than the kit lens?
i attached my lens to my camera and leave it in my bag, so will it deteriorate the lens? must i put them into the dry box?
