What this lens is good for
A first prime lens
A 50mm full-frame equivalent at f/1.8 for around $299, this is one of the best first primes for the system. The normal focal length is the most versatile there is, the fast aperture introduces shallow depth of field, and at 137g it is light and easy to carry everywhere. Full guide →
Everyday and low light
The normal view and bright aperture suit everyday shooting, portraits, and low light, keeping ISO down in dim conditions. It is not weather sealed and is the Olympus value alternative to the PRO f/1.2, but the optics and price make it an easy recommendation.
