Wutwut: Yes Nikon, continue to ignore customers with D90s and D7000s who really do need a fast wide prime. *Stomps off to Fuji*
what focal length are you looking for? this lens is a normal prime, not really wide. For DX, nikon users have enjoyed the 35mm/f1.8 since 2009, which gives the same field of view as the CX 18.5mm.
