Whats the best low profile set up for a DSLR? Lets say something like my 550D for going out with friends but not looking like a creep at venues with a DSLR (face it people look at you like you have a sniper rifle if your too obvious! :O). I know some venues specifically say "NO DSLR's" and some have gray areas where they say no "pro" cameras whatever that means 
Also prime lenses with wide angles seam to be a better choice if your doing any in city shooting. So I was thinking some sort of nice compact wide prime lense with a decently low f stop? I've looked at a few of Canon's but what is your guys input? These cameras are just barely over the "size limit" of allot of my pockets.
