OM System M.Zuiko Digital 45mm f/1.8

One of the best-value portrait primes in the Micro Four Thirds system — the 45mm f/1.8 delivers a flattering 90mm full-frame equivalent field of view with beautiful background separation. Compact, sharp wide-open, and excellent value for money. Compatible with every Micro Four Thirds camera ever made.

GearFrame's Take

An outstanding portrait prime that punches far above its price point — compact, sharp, and beautifully built.
