Canon EF-M 55-200mm f/4.5-6.3 IS STM

The only telephoto zoom you should buy for your EOS M camera. It's tiny, stabilized, and sharp enough, just don't expect miracles after sunset.

The STM autofocus is a genuine standout here, ranking in the 86th percentile. It's quick, accurate, and practically silent, which makes this lens a sneaky-good choice for video work on an M50 or similar body. The stabilization is even better, sitting in the top 10% of lenses we've tested. Canon claims 3.5 stops, and in our database, it holds up, letting you shoot at 1/30s at 200mm and get sharp results. Optically, it's a solid middle-of-the-pack performer. It's not going to out-resolve a pro L-series lens, but the single UD element does its job keeping purple fringing in check. The biggest surprise is how well it handles for a plastic fantastic build, it doesn't feel cheap, just light.

The Tamron 18-300mm for other mirrorless mounts is the dream superzoom that Canon never made for EF-M, offering way more range in a similar-sized package. If you're cross-shopping systems, that lens makes a strong case for Sony or Fuji. The Sigma 16-300mm is another do-it-all monster, but it's bigger and pricier. Within the Canon EF-M world, your only real alternative is adapting a bulky EF-S 55-250mm, which gives you more reach and a bit more light at the long end but completely ruins the compact vibe of your M camera. This Canon lens wins on portability alone.

With prices bouncing between $385 and $555 across vendors, you absolutely need to shop around. The sweet spot is finding it on the lower end of that range, where it becomes a fantastic value. At $550, you're getting into used DSLR telephoto territory, which offers better optics but at a massive size penalty. For the compact EOS M system, this is the only native telephoto game in town, and if you can snag it for under $400, it's an easy recommendation.

The Canon EF-M 55-200mm is the telephoto zoom that EOS M owners have been waiting for, and it mostly delivers. It's shockingly small and light for a lens that reaches out to a 320mm equivalent field of view, making it a no-brainer to toss in your bag for travel or a day at the park. The real headline is that it's sharp enough for real-world use, the image stabilization is a lifesaver, and the STM autofocus is dead silent and snappy for both stills and video. It's not going to win any low-light awards with that slow f/6.3 aperture at the long end, but for a $400-ish telephoto, it punches well above its weight in good light.

If you're primarily shooting in low light or want to blur the heck out of backgrounds, this isn't your lens. The slow variable aperture will frustrate you. Go grab a fast adapted prime or save up for a system with a brighter telephoto option. Macro shooters should also look elsewhere, the 19th percentile close-up performance is a real letdown.

If you own an EOS M camera and want more reach without turning your tiny setup into a Frankenstein rig, just buy this lens. It's the best native telephoto option by default, and thankfully, it's also a genuinely good performer. The stabilization and autofocus are excellent, and the image quality is more than enough for sharing online or making modest prints. Just know its limits: it's a daylight-only lens, and you won't be shooting any macro with it.
