Canon EF-S 24mm f/2.8 STM Lens

Canon EF-S 24mm f/2.8 STM Pancake Lens
Ultra-Slim Wide-Angle “Pancake” Prime Lens for Canon EF-S Mount – 38.4mm Equivalent Focal Length, Fast f/2.8 Maximum Aperture, STM Stepping Motor Autofocus, 1 Aspherical Element, Super Spectra Coating, Rounded 7-Blade Diaphragm, Includes Front & Rear Lens Caps (Good Condition / Minor Internal Dust)

The Canon EF-S 24mm f/2.8 STM is an ultra-slim, lightweight wide-angle “pancake” prime lens engineered specifically for APS-C-format Canon EF-S mount digital SLR cameras, delivering a natural 38.4mm full-frame equivalent focal length. Measuring less than one inch thick and weighing just a few ounces, this discreet lens provides a natural field of view that closely mirrors human vision, making it an exceptional choice for street photography, environmental portraiture, travel documentation, reportage, and everyday walk-around shooting.

Its optical configuration features 6 elements in 5 groups, incorporating one precision-molded glass aspherical element to effectively reduce spherical aberrations and optical distortion for corner-to-corner sharpness and clarity. Individual elements are treated with Canon’s Super Spectra Coating to minimize ghosting, flare, and internal reflections, preserving rich contrast and neutral color fidelity in challenging backlit conditions. Autofocus is powered by a smooth STM stepping motor paired with a rear focus system and high-speed CPU algorithms, delivering quick, accurate, and near-silent focusing performance ideal for both stills and video capture, complete with full-time manual focus override. A rounded 7-blade diaphragm produces smooth, pleasing out-of-focus background blur and natural circular bokeh.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: SLIM PANCAKE PRIME LENS UNIT. Supplied with the Canon EF-S 24mm f/2.8 STM lens, front lens cap, and rear EF-S bayonet dust cap.

Exterior & Physical Status: GOOD CONDITION. The ultra-compact composite barrel, slim manual focusing ring, and metal EF-S bayonet mount show minor cosmetic surface marks and normal signs of handling consistent with regular use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED OPTICAL DUST. The optical glass elements contain standard light internal dust particles typical of pre-owned primes, along with one visible larger dust speck on an inner glass element (tested and confirmed not to degrade image resolution, contrast, or everyday exposure). The STM autofocus motor operates quickly and quietly; the electronic manual focus ring responds smoothly; the aperture stops down accurately across all f-stops.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Ultra-Compact Pancake Form Factor: Measures less than 1 inch in depth, turning your APS-C DSLR into a pocketable, travel-ready setup for discreet street and daily photography.

Versatile 38.4mm Equivalent Perspective: Natural, wide-normal focal length captures landscapes, food, street scenes, and everyday snapshots without dramatic wide-angle distortion.

Fast f/2.8 Maximum Aperture: Enables low-light shooting capabilities and provides shallow depth of field for creative background separation.

Smooth STM Stepping Autofocus: Delivers swift, whisper-quiet AF tracking for still shooting and smooth focus transitions during video recording.

Aspherical Optical Glass Element: Limits spherical aberrations and distortion to achieve edge-to-edge sharpness and accurate rendering.

Super Spectra Multi-Coating: Suppresses flare and ghosting while maintaining natural color neutrality and high contrast in direct sunlight.

Rounded 7-Blade Diaphragm: Creates soft, pleasing background bokeh and circular specular highlights.

Native Canon EF-S Mount Compatibility: Seamlessly mounts to all Canon EOS APS-C digital SLR bodies (Rebel series, 60D, 70D, 80D, 90D, 7D series).
