Kudos to Nicolesy for this great find: Judge Joe Brown & Cheap Wedding Photographers. I'm not sure if His Honor Brown really knows his camera gear or is just repeating what his staff has researched for him, but it's entertaining and surprisingly not dumbed down camera lingo. Well worth the 10 minutes to watch the segment, regardless of your opinion of stupid shows like the "Judge [name]" and it's ilk.
Yet another reason I'm terrified to become a wedding photographer :)
