I'm interested in the X-Pro 1 body, but not particularly the lenses. I do quite a bit of night-time street work and the Fuji's wouldn't be fast enough for me. Has anyone tried lenses in the f/1.4 or less range with the Fuji body, also at higher ISOs? And I'm trying to go as wide-angle as possible.
Which lenses are you thinking about? Fuji has the "normal" 35mm f/1.4 which is better than great. Then there is the 18mm f/2, which is good. I do not know any faster lenses with shorter focal lengths which you could fit on the X-Pro1, except with the Metabones SpeedBooster. Which is one way of approaching this problem. No AF, but with wide enough manual focus lenses the good old zone focusing works fine.
