Hi, I drool at the X-Pro1 and the dropping prices and really want to buy one now on "outgoing" prices. I just want one prime with it, total focal length 25 to 50 mm (not longer than 50). What is the recommended lens? I rate sharpness highly (not only center) and fast aperture is a solid plus. Is the 35mm F2 where it´s at? I am used to Olympus lenses (MU 4/3), would the recommended lens be on par with the Olympus primes?
