Canon EF 50mm f/1.4 USM Lens

Canon EF 50mm f/1.4 USM Lens
Versatile Normal-Length Prime – WELL-USED CONDITION

The Canon EF 50mm f/1.4 USM is a versatile normal-length prime lens renowned for its natural perspective and bright, fast maximum aperture. Ideal for portraiture, street photography, and general shooting, the f/1.4 aperture provides excellent control over depth of field for beautiful subject isolation. Engineered with a Gaussian optics layout and two high refractive index glass elements, this lens is designed to deliver crisp image rendering and minimize optical distortion.

Equipped with a micro Ultrasonic Motor (USM) for fast, quiet autofocus and full-time manual override, this classic prime remains a staple focal length for Canon EF-mount shooters.

WELL-USED CONDITION NOTE (READ CAREFULLY BEFORE BUYING)

Please carefully review the optical and cosmetic notes below before purchasing. This lens exhibits distinct signs of heavy operational use, includes specific optical defects, and has been priced aggressively to reflect its condition:

Internal Lens Haze: There is a visible layer of internal haze inside the lens elements. This may impact overall contrast and cause a soft, dreamier aesthetic or increased flaring when shooting directly into bright light sources.

Nicked Filter Thread: The front plastic filter thread has a physical nick/ding on it. However, the threads remain functional, and the lens still successfully accepts and screws onto standard 58mm screw-in filters.

Exterior Cosmetic Wear: The lens barrel shows clear scuffs, rubbing, and surface wear from long-term handling, typical of a well-used workhorse lens.

Functional Status: Despite the internal haze and filter ring nick, the mechanical focus ring turns smoothly, and the micro USM autofocus system functions correctly. This lens is sold as-is—perfect for budget-conscious shooters, experimenters, or those looking for a vintage-glow effect portrait lens.

Key Features & Optical Attributes

Bright f/1.4 Maximum Aperture: The wide f/1.4 aperture setting allows a massive amount of light to hit the camera sensor, making it useful for low-light environments and affording fine control over selective focus techniques.

Gaussian Optics Layout: Utilizes a proven Gaussian optical design paired with two high refractive index elements to counteract spherical aberrations, helping to preserve rendering sharpness across the frame.

Super Spectra Coating: Multi-layered element coatings help suppress ghosting and lens flare, maintaining as much contrast and color neutrality as possible under challenging lighting conditions.

Micro USM Autofocus Drive: Features a micro Ultrasonic Motor (USM) that delivers responsive, accurate, and quiet autofocus performance, alongside full-time manual focus control for instant fine-tuning.

8-Blade Rounded Diaphragm: Incorporates a rounded eight-blade aperture system that produces a smooth, pleasing out-of-focus background quality (bokeh) when shooting wide open.
