Canon EF 50mm f/1.8 STM Lens

Canon EF 50mm f/1.8 STM Lens (Canon EF, Black)
Essential Full-Frame Normal Prime – Classic 50mm Focal Length (80mm APS-C 35mm Equivalent), Bright f/1.8 Maximum Aperture for Low Light & Shallow Depth of Field, Gear-Type STM Stepping Motor for Smooth, Near-Silent Autofocus & Full-Time Manual Focus Override, Super Spectra Multi-Coating for Contrast & Flare Suppression, Rounded 7-Blade Diaphragm for Pleasing Circular Bokeh, Robust Metal Bayonet Lens Mount, Compact & Lightweight 5.6 oz Walkaround Footprint, 49mm Front Filter Thread, Native Canon EF-Mount Compatible with Full-Frame DSLRs, APS-C Bodies, and Mirrorless via Adapters (Excellent Condition)

The Canon EF 50mm f/1.8 STM is a compact, highly versatile standard prime lens engineered for full-frame Canon EF-mount DSLRs (providing a classic 80mm short-telephoto portrait perspective when mounted on APS-C bodies). Widely recognized as an indispensable prime for portraiture, street photography, low-light events, and everyday documentation, this re-engineered classic balances remarkable optical sharpness with an ultra-portable profile. Weighing just 5.6 ounces, it integrates seamlessly into any camera kit, providing accessible wide-aperture performance without the bulk of larger portrait lenses.

The lens utilizes a refined optical formula of 6 elements in 5 groups, enhanced by Canon’s Super Spectra coating on individual elements to suppress flare and ghosting while maintaining neutral color fidelity and strong contrast in backlit situations. Its bright f/1.8 maximum aperture excels in dim ambient light, allowing for fast shutter speeds without excessive ISO values, while delivering shallow depth-of-field control to isolate subjects against softly blurred backgrounds. Autofocus is powered by a gear-type STM stepping motor supported by high-speed CPU algorithms, delivering quick, precise, and quiet focusing for stills along with smooth focus transitions for video capture. Constructed with a durable metal bayonet mount, a tactile manual focusing ring, and a rounded 7-blade circular aperture, this prime lens delivers exceptional all-around utility in top-tier shape.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: ESSENTIAL NORMAL PRIME OUTFIT. Supplied with the Canon EF 50mm f/1.8 STM lens, genuine Canon 49mm front snap-on lens cap (E-49), and genuine Canon rear EF-mount lens dust cap (E). (Camera bodies, 49mm screw-in filters, dedicated ES-68 bayonet lens hoods, and storage pouches sold separately unless pictured).

Exterior & Barrel Status: EXCELLENT CONDITION. The matte black composite barrel, finely knurled manual focus ring, AF/MF switch housing, and metal bayonet mount show minimal to no signs of previous handling, with no deep scratches, dings, scuffs, or edge finish rub marks. All white painted focal length indicators, Canon badging, and barrel switch markings remain crisp, clean, and fully legible.

Optical Status: EXCELLENT CONDITION. Both front and rear external optical glass surfaces are pristine and completely free of scratches, scuffs, cleaning marks, haze, fungus, or element separation. The internal optical assembly is clean and clear with only trace, negligible dust specks typical of standard handling; bench testing confirms these specks do not impact resolving power, edge contrast, or color fidelity across working apertures. Factory Super Spectra coatings remain immaculate.

Mechanical & Electronic Diagnostics: FULLY FUNCTIONAL. The internal STM stepping motor acquires focus swiftly, accurately, and quietly; full-time manual focus override engages smoothly with consistent electronic ring damping; the physical AF/MF toggle switch clicks firmly into place; the rounded 7-blade diaphragm stops down cleanly without sticking or oil residue; the metal bayonet mount locks securely onto camera bodies with zero play; gold-plated EF electronic contacts communicate Exif metadata and aperture commands reliably with zero camera error codes.
