Extension tubes. These guys, in fact. I was surprised to see their reviews for the price... usually with photography, you get what you pay for. Granted, with them, I'll lose autofocus (which I never use anyway) and aperture, but I'll live. I think there's some kind of trick, like you can set the aperture, hold a button, and take the lens off and it locks your aperture setting in, lol. I'unno. I'm already getting them for Christmas, I'm just going to have to practice my willpower to not beg my wife to have 'em early, haha. Thanks, though.
