When nikon introduced its full-frame D4 for pros in January, it also had something for its amateur fans: the 85mm f/1.8G AF-S Nikkor ($500, street)—the fifth 85mm for FX bodies in its current catalog. This newest 85mm also belongs to another Nikon subset: It’s one of a trio of fast f/1.8 primes, along with the 28mm and 50mm, that almost mirrors Nikon’s famed trio of f/1.4 primes, the much-lauded 24mm, 50mm, and 85mm. The f/1.8s, however, are lighter, more compact, and significantly more affordable.
