I got my quick and easy wide angle converter lens today ($10 on Amazon). It's supposed to be a .45x, giving my 14mm lens an effective focal length of 6.3mm (or a 12.6mm 35mm equivalent). It's definitely neat (it also has a macro adapter), and as you can see in photo below, it gives does widen the field of view for my lens very nicely. There's some blurring around the edges, and I'm sure it's not the greatest piece of glass ever, but it'll be fun to fool around with (and get some nice pictures of the apartment once I get my new TV stand).
