Depends on what you're after, and why you're looking alt.
The Fuji 18mm (27mm effective) and 35mm (53mm effective) are incredible lenses for size, weight, and quality. Sharp from wide open, aperture ring on the lens, just not AS nice to MF as a non-fly-by-wire design. But if you're MF'ing slowly, it's not a problem.
I've shot a Tamron Adaptell 17mm f/3.5 adapted to EOS then adapted to Fuji X-- and it seems great too. But I don't see why I'll use this over the 18mm, which is TINY, has a wide aperture, and is relatively fast to AF. I've also used an OM 24mm f/2.8 -> EOS -> X... fine too.
But my advice: Go with the Fuji Primes. Distortion also heavily corrected by SOOC jpeg or native RAW processing.
