How about this as a nice set of primes for the G1?
I think I saw somewhere on the net, maybe photo.net, I can't remember, that someone had mounted an Arriflex 9mm f1.9 lens. "Mmmm, nice and wide and fast," I thought. Then I came across this auction. Wouldn't be a bad set of primes to play with, I suppose...
