Reviewer Consensus

Strong

The Canon EF-M 22mm f/2 STM is a remarkably compact and lightweight pancake prime that offers sharp, high-contrast images for APS-C mirrorless users. Although it lacks image stabilization and exhibits some corner vignetting at wide apertures, it remains a highly recommended, versatile upgrade for travel and daily shooting.

What the Reviewers Say

  • Cameralabs

    Canon's EF-M 22mm f2 is a compact prime lens for EOS mirrorless cameras with APSC sensors, upon which it delivers classic 35mm equivalent coverage; note it's not compatible with Canon DSLRs.

    The Canon EF-M 22mm f/2 STM is a capable wide-angle pancake prime that will appeal most to travel and reportage photographers looking for a very lightweight and inconspicuous lens.

    Indeed, I don't know why every Canon EOS M user doesn't own this lens (similar to why I don't understand why some Nikon DX DSLR users don't own the 35mm f/1.8G DX lens).

    This is a superb general-purpose lens for the EOS M series of cameras. It's ultra sharp, and has the same quality optics as Fuji's 23mm f/2 on their X100 series, or LEICA's SUMMICRON 35mm f/2 ASPH.

    I can confidently say, that for Canon EOS-M users, the Canon 22mm F2 STM pancake lens is a must have in your camera bag. This is a no-brainer upgrade from the kit lens, giving you improved results and a better shooting experience.

    If you're just starting out with the Canon M50 or any other Canon crop sensor mirrorless cameras, check this lens out. I think you'll be surprised.

    If you've got a Canon M-series body, be it M50, M6 II, M6, whatever, and you haven't got the, and you haven't got the Canon EF-M 22mm f/2 STM lens, then I'd highly recommend that when you get it, because you're gonna get some awesome, awesome images.
