Yeah...that's true. These Pana lenses are expensive. But...some folks compare them to Canon's L lenses (in performance). And we all know how expensive those are.
the voiglander lens that the person posted in that video would likely allow you to shoot a club with ambient lighting. f0.95 is incredible fast.. that said its a manual focus lens and one of the merits of the gh2 is its video autofocus. so i would go for the f1.7 20 mm pancake but this lens is non-stabalized... I have been wracking my brain to figure out a fast lens with stabalization but there appears to be nothing.
Still it shoudl work fine especially tripod'd. But this IS a guess.
