The ROKINON® AF 85mm F1.4 Full Frame Telephoto for Canon RF mount is arguably the best value, high performance and affordable AF portrait prime available, superbly suited for both amateurs and professionals.

This ROKINON RF mount prime delivers breathtaking bokeh, impressive image quality and exceptional resolution. Its advanced autofocusing technology includes a DLSM (Dual Linear Sonic Motor) that utilizes ultrasonic vibrations to provide fast and silent autofocus performance. Protocols developed specifically for a short telephoto lens precisely control the operation of the DLSM.

The ROKINON AF 85mm F1.4 is a perfect match for Canon R mirrorless cameras. Specifically engineered with a shorter flange back length, the resulting reduction in length and weight enhances balance, portability, and user experience. It is a bright spot in the image capture sector, offering advanced still and video features in a superbly crafted package.

The optical design of ROKINON’s AF 85mm F1.4 RF incorporates special elements (One Extra Low Dispersion and four High Refractive Index elements) with UMC coatings, a fast F1.4 maximum aperture, and a rounded nine blade diaphragm. Together, they maximize image quality and contrast even at wide open apertures with exceptionally smooth bokeh. With a ROKINON AF 85mm F1.4 RF lens, you can unleash your creative talents and produce pleasing out-of-focus backgrounds that convey a three-dimensional perspective to your portraits.

ROKINON autofocus lenses are loaded with features, and the new AF 85mm F1.4 RF is no exception. Weather sealing protects against dust, light rain and moisture. An AF/MF switch allows quick and easy shifting between auto-focus and full manual focus operation, and an internal focusing design eliminates changes in length. The non-rotating 77mm filter mount allows the use of polarizing and other filters that require precise positioning.

Not to be overlooked is the capability to calibrate and update the AF 85mm RF if the need arises. ROKINON AF lenses can be connected to your computer to update firmware and calibrate lens performance using ROKINON Lens Manager Software and a ROKINON Lens Station.

The ROKINON AF 85mm F1.4 Canon RF lens includes a removable lens hood, reversible for easy storage, along with a soft lens pouch.

Optical Construction

Features

Exceptional rendering even at the brightest apertures

The AF 85mm F1.4 RF’s optical design minimizes optical aberrations, while maximizing the image quality from corner to corner. Its detailed rendering results in exceptional image quality, even on the latest high-resolution full-frame cameras; and its bright maximum aperture means you can enjoy this excellent performance even when shooting indoors or in darker conditions.

Controlling chromatic aberration with ED glass

The AF 85mm F1.4 RF features a total of 11 glass elements; the ED (Extra Low Dispersion) element has been incorporated into its precise achromatic design. This design corrects chromatic aberrations, and creates quality results, with peripheral softness also being well-controlled.

Expressing a visual feeling of depth

The short telephoto focal length, combined with the wide maximum aperture of f/1.4, enables photographers to achieve a dramatically shallow depth-of-field, setting your pictures apart from those taken with other lenses. This optic offers great creative freedom: it yields images with depth, while maintaining an appropriate distance from the subject; it separates subject and background naturally, providing an impressive visual feeling of depth.

Exceptional bokeh

The lens’s attractive bokeh, created through precise lens polishing, adds a great feeling of depth and space in your photographs. Also, its aperture mechanism comprises 9 precisely-controlled iris blades, providing natural, circular, out-of-focus highlights at all apertures. With this smooth bokeh, achieved through various optical technologies, you can create images full of character in your portrait or subject photography.

Designing a complex optical system with High Refractive elements

Four HR (High Refractive) elements, made of special materials with an outstanding refractive index, improve optical performance and enable a compact optical design. The AF 85mm F1.4 RF was designed from the ground-up with this technology, to lessen its users’ burden with a shorter length and smaller size.

Weather sealing design for protection from adverse conditions

The aluminum body, designed with precision by mechanical engineering specialists, has only three spaces in its basic design. Weather sealing covers even these small spaces to effectively protect the lens from dust and rain. This protective design enables users to capture the moment outdoors in any environment, providing the dependability you need to keep shooting.

Outstanding contrast with Ultra Multi Coating (UMC) technology

Rokinon’s Ultra Multi Coating (UMC) technology is applied through a thorough cleaning process, followed by Ion-Beam Sputtering (IBS), which controls the spread of reflections while still enabling a high transmittance of light. This UMC technology reduces unwanted reflections and provides crystal clear image quality, minimizing flare and ghosting effects in high contrast environments, such as backlit pictures and nightscapes.
