Every body in the catalogue that takes Canon EF-M lenses, newest first. Prices are the best new price from a UK retailer we track.
Discontinued lens system. Canon EF-M lenses are no longer made new. Bodies and lenses still work and are still sold, but the range will not grow.
19 Canon EF-M lenses in the catalogue. Native means made by a company that also makes Canon EF-M bodies; third-party is everyone else.
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.
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 Canon EF-M; glass from a shorter one needs corrective optics.
33 other mounts adapt onto Canon EF-M without corrective glass. Focus and framing only; autofocus and aperture control depend on the adapter.
Current camera mounts that accept Canon EF-M glass: 3 with a plain or thin adapter.
The lens-ecosystem scores Camera Match uses when it ranks Canon EF-M bodies for wildlife, sports, portrait, macro, food, architecture and astro. Scored 0–10 from the native lenses buyable new, with the reasoning shown.
Only native telephoto still sold new is EF-M 55-200 (88-320 mm equiv) — nothing native reaches 400 mm equiv; EF telephotos need the EF-EOS M adapter (not counted). Source ↗
Sigma 56 f/1.4 DC DN (90 equiv, f/1.4) is the one qualifying lens still made; Canon's EF-M 32 f/1.4 is 51 mm equiv, too short. Source ↗
EF-M 28 f/3.5 Macro IS STM (1.2×, still sold new by Canon UK), Laowa 65 f/2.8 2× and Laowa 100 f/2.8 2× in EF-M; short working distance on the 28. Source ↗
EF-M 11-22 (17.6-35 equiv) misses the 16 mm line; Laowa 9 f/2.8 Zero-D (14.4 equiv, MF) and Samyang 12 f/2 (19) exist; no shift lens. Source ↗
Samyang 12 f/2 (19 equiv f/2, MF), Laowa 9 f/2.8 Zero-D (14 equiv f/2.8), Sigma 16 f/1.4 DC DN (25.6 equiv, just outside) — MF-only options but astro tolerates that. Source ↗

Lens counts and picks come from the catalogue and the lens engine, so they change as lenses are added. Ecosystem scores are researched per mount with a source and feed Camera Match's lens-range feature. How scoring works · All mounts
