The Olympus M.Zuiko 25mm f/1.8 is a tiny little lens that punches well above its weight.

Digital Camera World Verdict

Barely bigger than a pancake lens, this Olympus gives the same field of view as using a 50mm standard prime on a full-frame camera, along with a fast f/1.8 aperture. Available in black or shiny silver, it’s ideal as an unfeasibly compact and lightweight ‘nifty fifty’ for any Micro Four Thirds camera, taking full advantage of the 2x crop factor. Image quality and all-round performance are highly impressive, but it’s pretty pricey for an f/1.8 standard prime.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Ask a full-frame photographer to choose just one prime lens and it would often be a 50mm, thanks to its entirely natural viewing perspective. Taking the 2x crop factor of Micro Four Thirds cameras into account, the Olympus M.Zuiko 25mm f/1.8 gives the same field of view. Sure, f/1.2 and f/1.4 lenses enable faster shutter speeds under low lighting conditions, and a tighter depth of field, but f/1.8 is also a favorite for keeping a reign on size, weight and expense.
