Nikon makes some incredible prime lenses, from the illustrious 58mm f/.95 Noct to the 50mm f/1.2 S — the latter of which is the more practical, yet is very expensive even though it is very good. Nikon also makes a full spread of f/1.8 and f/2 prime lenses across a wide range of focal lengths. What Nikon have curiously ignored are any f/1.4 primes, at least until recently.
