Lenses 35/21 Gears 46/20
I think you will really enjoy this, and its pretty low-risk, financially. I use a generic M-mount adapter, not Fuji's, it was less than $20 and gets the job done. And no need to work about focus lag when using legacy glass; as Lukitas says, pure shutter lag is quite minimal.
I could get generic M adapter for this price on e-bay.
I'm reading about M lenses on X series and it is missleading.
Some are saying corners are soft, some are showing examples with fine corners.
