Canon 22mm f/2 STM Lens for EF-M Mount, Graphite Black {43}

Canon's pancake prime: 35mm equivalent f/2 for EF-M shooters.

At 24mm long and 105 grams, the EF-M 22mm f/2 STM is essentially flush with any EOS M body it mounts on, which means the camera actually fits in a jacket pocket. The metal barrel and mount give it a solidity that belies the weight, and the 43mm filter thread keeps accessory costs reasonable. One aspheric element in a 7-element, 6-group design keeps distortion in check at this focal length, and the 7-blade diaphragm produces a rounded aperture stopped partway down.

The f/2 maximum aperture on an APS-C sensor gives you genuine subject separation at portrait distances and real low-light capability without flash. Minimum focus distance sits at 0.15m, close enough to fill the frame with small objects at 0.21x magnification. The STM motor earns its keep in video: autofocus transitions are quiet enough that the built-in microphone won't pick them up, and full-time manual override lets you pull focus mid-clip without switching modes.

On an APS-C sensor, 22mm translates to roughly 35mm equivalent, the field of view that travel and street photographers have trusted for decades. This lens has a well-established track record in the EF-M ecosystem, and at its size and weight, it's the logical first prime for anyone building out an EOS M kit.

Who It's For

Street photographers working the EOS M system get a 35mm-equivalent angle of view with a f/2 aperture that handles mixed urban light without drawing attention. Travel shooters benefit from the pancake form factor: at 24mm long and 105g, this lens doesn't change the carrying profile of the camera. Video-focused creators using EOS M bodies will appreciate the STM motor's near-silent focus pulls, which stay off the audio track. Close-up and food photographers can work down to 0.15m, getting within six inches of a subject without a macro attachment.

FAQ

What's the 35mm equivalent focal length on an EOS M body?

22mm on APS-C translates to roughly 35mm equivalent, the classic field of view for travel and street work.

Can you use this lens for video?

Yes. The STM motor delivers silent autofocus transitions that won't be picked up by the built-in microphone, and full-time manual override lets you pull focus mid-clip without switching modes.

How close can you focus?

Minimum focus distance is 0.15m (5.91 inches), with 0.21x magnification - close enough to fill the frame with small objects.

Will the 7-blade diaphragm produce good bokeh?

The rounded aperture blades create smooth bokeh when stopped partway down, and the f/2 maximum aperture on APS-C gives genuine subject separation at portrait distances.

What does the metal barrel and mount actually mean for handling?

It means durability and a solid feel that belies the 105-gram weight. The lens sits flush against the camera body without adding bulk.

Is autofocus smooth and quiet?

The STM stepper motor was designed for silent operation - ideal for video work and situations where autofocus noise matters.

What size filters does this lens use?

43mm filter thread keeps accessory costs reasonable and fits standard filter sizes across most kit lenses.
