Canon EF 85mm f/1.8 USM Lens

Canon EF 85mm f/1.8 USM Lens
Legendary Short-Telephoto Portrait Prime – Fully Operational / Project Condition (Internal Dust & Early Fungus)
The Canon EF 85mm f/1.8 USM is a legendary short-telephoto prime lens universally prized for its flattering focal length, slightly compressed perspective, and exceptional portrait-rendering capabilities. Designed natively for full-frame Canon EF-mount DSLRs and highly popular for adaptation to modern mirrorless systems, this lens is a staple tool for portraiture, indoor sports, and event photography.

Its ultra-bright f/1.8 maximum aperture lets in massive amounts of light for low-light environments while offering razor-thin depth-of-field control for dramatic subject isolation. Driven by a powerful, ring-type Ultrasonic Motor (USM), it delivers blazing fast, near-silent autofocus tracking. This specific unit is priced accordingly as a technician’s cleaning project or a creative experimental optic.

Please note: This lens is in fully operational condition. However, internal inspection reveals a standard accumulation of dust alongside early signs of potential fungus growth inside the glass elements. All sales are final.

Key Features & Portrait-Length Performance
Flattering 85mm Perspective: Delivers a classic, compression-rich perspective on full-frame sensors, or transforms into a powerful 136mm equivalent tight telephoto prime when mounted to crop-sensor APS-C Canon DSLR bodies.

Bright f/1.8 Maximum Aperture: The wide f/1.8 opening maximizes light transmission for handheld low-light shooting and combines with an 8-blade diaphragm to yield creamy background blur and round out-of-focus highlights.

Ring-Type USM Autofocus Drive: Equipped with a high-speed, ring-type Ultrasonic Motor that utilizes internal focusing mechanics. Autofocus is instantaneous, precise, and quiet, featuring full-time manual focus override.

Non-Rotating Front Design: The front lens barrel remains completely stationary during focus tracking, making it incredibly easy to use circular polarizers or graduated neutral-density filters without constant realignment.

Super Spectra Coatings: Individual lens elements feature multi-layer Super Spectra coatings to control internal reflections, ghosting, and lens flare, preserving color fidelity and high contrast.

Item Condition & Diagnostic Notes
Functional & Mechanical Performance: FULLY OPERATIONAL. This lens has been thoroughly tested and all electronic and mechanical features perform perfectly. The USM autofocus drives instantly and locks onto targets accurately, manual focus is smooth, and communication with the camera body is completely stable.

Optical State (Dust & Early Fungus): PROJECT CONDITION. Internal diagnostic inspection reveals standard fine dust particles alongside early signs of potential fungus spores beginning to form inside the lens elements. At its current early stage, this growth does not visibly degrade center resolution or contrast in normal test shots. However, it is an ideal candidate for professional cleaning or an affordable option for shooters looking for an organic, vintage look. The glass surfaces are free of deep scratches or separation.

Cosmetic Presentation: The exterior composite barrel is in overall good cosmetic shape, showing standard light surface scuffs and normal signs of regular handling consistent with its age. The metal mounting bayonet and front filter rings are structurally intact.

Included Accessories: Lens only. No front or rear lens caps are included.
