Best Micro Four Thirds lenses by genre
Top three per genre from the lens engine, scored on this lens's own format. The same scores you see on each lens page; Gear Builder re-scores them for the exact body you pick.
Flange distance & adapting
A plain adapter is a spacer: it can only add distance between lens and sensor. Glass from a mount with a longer flange distance adapts cleanly onto Micro Four Thirds; glass from a shorter one needs corrective optics.

How deep is the Micro Four Thirds lens range?
The lens-ecosystem scores Camera Match uses when it ranks Micro Four Thirds bodies for wildlife, sports, portrait, macro, food, architecture and astro. Scored 0–10 from the native lenses buyable new, with the reasoning shown.
M.Zuiko 100-400 IS II (200-800 equiv, £1,165–1,250), Panasonic Leica 100-400 II (~£1,200), M.Zuiko 75-300 II (150-600, under £400), 300 f/4 PRO (600), 150-400 f/4.5 TC PRO (300-1000); the cheapest route to 800 mm equivalent, but slow apertures and smaller sensor. Source ↗
M.Zuiko 45 f/1.2 PRO (90 equiv), Panasonic Leica 42.5 f/1.2 Nocticron (85), M.Zuiko 75 f/1.8 (150, just outside), Sigma 56 f/1.4 (112); nominal apertures qualify but 2× crop means ~f/2.4 equivalent depth of field. Source ↗
M.Zuiko 60 f/2.8 Macro (1:1 = 2× equiv), M.Zuiko 90 f/3.5 Macro IS PRO (2× native = 4× equiv), Panasonic Leica 45 f/2.8 Macro (1:1), M.Zuiko 30 f/3.5 (1.25×), Laowa 50 f/2.8 2× — the strongest macro system per pound. Source ↗
M.Zuiko 7-14 f/2.8 PRO (14-28 equiv), Panasonic Leica 8-18 (16-36), M.Zuiko 8-25 f/4 PRO (16-50), Laowa 7.5 f/2 (15), Laowa 6 f/2 Zero-D (12); no shift or tilt-shift lens for the mount. Source ↗
Laowa 7.5 f/2 (15 equiv f/2), M.Zuiko 12 f/2 (24 f/2), M.Zuiko 7-14 f/2.8, Panasonic Leica 12 f/1.4 (24 f/1.4), M.Zuiko 17 f/1.2 (34, outside); apertures qualify nominally, but the 2× crop costs two stops of light gathering versus full frame. Source ↗
