Micro Four Thirds: what each focal length frames

Every camera on this page has a 2x crop factor, so whatever the brand, a lens frames like its focal length times 2x on full frame. A 50 mm lens frames like 100 mm on full frame on all 6 of them.

To see any of these focal lengths live, Prospekt (Lens Simulator: Prospekt on the App Store) turns your iPhone into a viewfinder for your camera body: pick the body and a focal length from 14 to 300 mm, point the phone, and the screen frames what that lens would. iPhone app, $3.99 once, no subscription.

What each focal length covers at a distance

Covers is the width x height of the scene with the camera held horizontally. Close up, real lenses frame a little tighter than these numbers.

24 mm	0.7 × 0.5 m	1.4 × 1.1 m	2.2 × 1.6 m	3.6 × 2.7 m	7.2 × 5.4 m
35 mm	0.5 × 0.4 m	1.0 × 0.7 m	1.5 × 1.1 m	2.5 × 1.9 m	4.9 × 3.7 m
50 mm	0.3 × 0.3 m	0.7 × 0.5 m	1.0 × 0.8 m	1.7 × 1.3 m	3.5 × 2.6 m

50 mm: about 5.8 m (19 ft) for a full-body portrait, 1.6 m (5.3 ft) for head and shoulders.
85 mm: about 9.8 m (32 ft) for a full-body portrait, 2.7 m (9.0 ft) for head and shoulders.
