Olympus Zuiko 50mm f/1.4
Introduced: 1973

Zuiko 50mm f/1.4 is Olympus's fast standard prime in the OM Zuiko lineup — the brighter sibling of the f/1.8, with the same Maitani compact-design priority. The Zuiko 50/1.4 is widely considered one of the finest 50mm primes ever made, with rendering character that has a small but devoted following.
