so i got the 14-42 not so good lens that comes with the gh2 and now i bought the 20mm 1.7f which is superb...what else do i need? i feel like now i have to go out and by the 14-140mm from pana for my short films. do you think these 3 will be enough for me to start working on some nice projects? also what do you guys recommend for lighting. i think i might buy a 3 kit softbox 4500w 5 bulbs..what do you guys think?
