the 20D's are known as dust traps, but i give my cameras a good seeing to every week with a Rocket Blower and i rarely go above f14 (f14 so i can get good prop blur on aircraft with rotors/props) i mainly shoot f1.8-8.0, as i shoot with a 2 body set up i also have less hassle with crap on the sensor as i don't lens swap as much as i used to..
re: Jessops, you're lucky if you get someone who actually knows what they're talking about and isnt' a spotty nosed student who knows squat, i went into hold a 40D last year and the '
assistant' was trying to talk me through the features, i asked about the ISO switching and he tried to hold the ISO button down while trying to turn the dial to adjust it!.. when he enquired why i needed such high ISO, i told him that i do alot of Gig work, he then tried to tell me how great at shooting gigs he was..
