EF2818U
Product introduction Large aperture, wide angle 28mm with attractive natural depiction and beautiful bokeh

The optical system uses a replica aspherical lens that supports larger apertures.

Along with making the optical system compact, spherical aberration is reduced as much as possible to achieve sharp images.

Rear focus mechanism and drive system ring USM realize quiet and high-speed AF

Full-time manual focus with outstanding operability, filter frame non-rotating method

From Discovery Japan Aspherical lens Aspherical lens Large-diameter lens spherical aberration correction, wide-angle lens distortion correction, zoom lens miniaturization

Aspherical lenses were born to solve these three themes.

Ring USM Ring USMUSM (Ultrasonic Motor) = Ultrasonic motor has high torque / high response and supports quick focusing.

It has ideal characteristics as a lens drive motor, such as almost no operating noise.

Rear focus Technology that reduces the total weight of moving lenses by using a part of the rear focus lens configuration as a focus lens.

Achieves high-speed, precise AF control, excellent holding balance, and compactness.

Full-time manual focus Full-time manual focus After autofocus, this function enables immediate manual focus by simply rotating the focus ring after one-shot AF so that the photographer can make final focus adjustments.
