Canon RF 28mm f/2.8 STM Lens

Canon EF-S 24mm f/2.8 STM Lens

The Ultimate "Pancake" Walkaround Prime

The Canon EF-S 24mm f/2.8 STM is a marvel of optical miniaturization. Affectionately known as a "pancake" lens due to its incredibly flat and thin profile, this wide-angle prime is designed specifically for Canon’s APS-C crop-sensor DSLR cameras. By adding virtually zero bulk to the front of your camera, it effectively transforms a traditional DSLR into a highly portable, grab-and-go setup that feels more like a heavy-duty point-and-shoot.

Because of the APS-C crop factor, the 24mm focal length acts as a 38.4mm equivalent lens. This is widely considered a "perfect normal" perspective—falling right between a standard 35mm and 50mm—making it an exceptional everyday walkaround lens for street photography, travel, food, and casual family portraits.

Why You'll Love This Lens

• Unbelievably Compact Design: Measuring less than an inch thick (0.9 in / 22.8mm) and weighing just 4.4 ounces (125g), this is the thinnest and lightest lens in the EF-S lineup. It makes carrying a DSLR on a neck strap all day completely effortless.

• The Perfect "Normal" Perspective: The 38.4mm equivalent focal length provides a highly natural, versatile field of view that closely mimics human vision. It's wide enough for environmental context, but tight enough to avoid the extreme distortion of ultra-wide lenses.

• Fast f/2.8 Aperture: Stepping up to an f/2.8 prime is a massive advantage over standard 18-55mm kit lenses (which typically restrict your aperture to f/4 or f/4.5 at this focal length). The f/2.8 aperture allows in significantly more light for cleaner indoor shots and helps blur the background to make your subjects stand out.

• Smooth and Quiet STM Autofocus: The stepping motor (STM) provides fast and accurate autofocus for still photography, while delivering incredibly smooth, near-silent focus transitions during video recording—crucial for preventing distracting motor noises from ruining your audio.

• Get Surprisingly Close: It boasts a minimum focusing distance of just 6.3 inches (0.16m), allowing you to get right up to your subject. When combined with the f/2.8 aperture, this close-focusing ability allows you to capture stunning details of food or flowers with a beautiful, creamy background blur.

• Incredible Value: This lens offers arguably the best "bang for your buck" in the entire Canon ecosystem, delivering fantastic sharpness and color rendition at a highly accessible price point.

Technical Specifications

Things to Note

Because this is an EF-S mount lens, it is engineered exclusively for Canon's APS-C sensor DSLRs (like the Rebel series, 70D, 80D, 90D). It cannot be mounted on full-frame Canon DSLRs (like the 5D or 6D series). However, it can be easily adapted to Canon's modern mirrorless EOS R-series cameras via the EF-EOS R Mount Adapter.

Secondly, to achieve its incredibly tiny "pancake" footprint, this lens does not feature built-in Optical Image Stabilization (IS). When shooting handheld in very dark environments or recording walking video footage, you will need to keep your shutter speed relatively fast to avoid motion blur.
