Canon EF-S 24mm f/2.8 STM Pancake review

Canon’s slimmest EF-S lens, a 24 mm f/2.8 pancake for APS-C DSLRs, with 4,451 ratings at 4.7 stars, at about $159 from a third-party seller.

The pancake

Canon calls it the slimmest and lightest lens in the EF-S range. On a Rebel T7, it turns a bulky DSLR into something that fits a coat pocket.

A normal view, not ultra-wide

Canon gives 38 mm equivalent on APS-C. That frames like a slightly wide normal lens: good for street, travel and food, not for big interiors.

Close and bright

It focuses down to 0.16 m with 0.27× magnification, and f/2.8 is brighter than a kit zoom at 24 mm.

Seller

Clogic sold it at about $159, recording serial numbers, with 11 units left.

What people ask before they commit

Is it really a wide-angle lens?

On APS-C, Canon gives 38 mm equivalent, a mild wide-normal view. An equivalent focal length is a calculation: it describes the field of view on a full-frame camera. The focal length engraved on the lens never changes.

Will it fit my Canon R50?

With Canon’s EF-to-RF adapter. It is an EF-S DSLR lens.

Can I focus manually?

Yes. Full-time manual focus works while in One Shot AF.

A small, cheap and well-loved lens for Canon APS-C DSLRs. For a true wide angle, look at the Sigma 16mm or Samyang 12mm on Sony.
