Concerning this new GH2 lens -Panasonic LUMIX G 14mm f/2.5 ASPH LENS - or for that matter, the current pancake that's already available for the GH1, what sort of shot(s) would I use such a lens for if I was making an amatuer short film? What does it give me? I've made lots of short vids with my Pani camcorders but I'm just learning all about the VDSLR interchangeable lens scene. Thanks.
