Canon EF 85mm f/1.8 USM Lens

Canon EF 85mm f/1.8 USM Lens
Classic Short-Telephoto Portrait Prime Lens for Canon EF Mount – Fast f/1.8 Maximum Aperture, Ring-Type Ultrasonic Motor (USM) AF, Super Spectra Multi-Coating, Non-Rotating Front Element, Rounded 8-Blade Diaphragm, Includes Front & Rear Lens Caps (Well Used Condition / Internal Dust & Two Minor Blemish Spots)

The Canon EF 85mm f/1.8 USM is a legendary short-telephoto portrait prime lens engineered for full-frame and APS-C Canon EF-mount digital DSLRs and 35mm film SLRs (providing a 136mm equivalent focal length on APS-C bodies). Widely praised for its practical focal length, pleasing perspective compression, and lightweight form factor, this lens is well-suited for studio portraiture, weddings, event coverage, street shooting, and available-light photography. Its bright f/1.8 maximum aperture allows for substantial subject isolation with smooth background blur while offering dependable exposure control in low-light environments.

The optical formula utilizes 8 elements in 7 groups treated with Canon’s Super Spectra Coating to suppress internal reflections, flare, and ghosting for high contrast and neutral color accuracy. Autofocus is powered by a high-torque ring-type Ultrasonic Motor (USM) paired with high-speed CPU algorithms, delivering quick, precise, and virtually silent autofocus with seamless full-time manual focus override. Designed for convenience with screw-in filters, the front element group does not rotate during operation, allowing effortless use of circular polarizers and graduated ND filters. An 8-blade circular diaphragm rounds out the build to produce natural, smooth out-of-focus background highlights.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: SHORT-TELEPHOTO PRIME LENS UNIT. Supplied with the Canon EF 85mm f/1.8 USM lens, front lens cap, and rear bayonet dust cap.

Exterior & Physical Status: WELL USED CONDITION. The composite barrel, ribbed manual focus ring, distance window, and metal EF bayonet mount exhibit visible cosmetic surface marks, scuffs, edge rubbing, and handling wear consistent with regular professional use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED INTERNAL BLEMISHES. The optical assembly contains light internal dust particles typical for vintage primes, along with two small ~2mm blemish spots located on internal glass elements (tested and confirmed not to affect captured image quality or real-world optical exposure). The ring-type USM autofocus motor tracks swiftly and quietly; the full-time manual focus mechanism operates smoothly; the electronic aperture stops down accurately across all f-stops.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Flattering 85mm Portrait Compression: Delivers classic short-telephoto perspective that naturally renders facial proportions and isolates subjects from backgrounds.

Bright f/1.8 Maximum Aperture: Excels in challenging low-light conditions and creates shallow depth of field for creative selective-focus techniques.

Fast Ring-Type USM Autofocus: Delivers quick, whisper-quiet, and accurate AF tracking with full-time manual focus override.

Super Spectra Coating: Minimizes ghosting and flare while preserving rich contrast and accurate color rendition in direct or backlit settings.

Non-Rotating 58mm Front Filter Thread: Front barrel does not rotate during focusing, facilitating the use of circular polarizers and gradient filters.

Rounded 8-Blade Diaphragm: Softens out-of-focus areas for creamy, natural background bokeh and circular specular highlights.

Full-Frame & APS-C Native EF Compatibility: Mounts natively to all Canon EOS full-frame DSLRs, APS-C DSLRs (136mm equivalent), and Canon 35mm film cameras.
