Thank you for purchasing the Rokinon Autofocus 85mm F1.4 Sony E mount lens. It’s advanced optical design is engineered
specifically for Sony mirrorless cameras.


  • The Rokinon AF 85mm F1.4 is designed for optimal quality imaging with the most advanced Sony full-frame image sensor cameras.
  • It performs equally as well on Sony APS-C sensor mirrorless cameras as a high-speed 127.5mm equivalent AF telephoto lens.
  • It’s perfect for portraits and candids while offering a performance that competes with the best in its class.
  • The fast 1.4 maximum aperture provides exceptional low-light performance and selective focus control.
  • Its eleven elements in eight groups design utilizes four High Refractive Index elements, one Extra Low Dispersion element, and UMC anti-reflective coating on all surfaces. This helps to minimize aberrations and maximize image quality and contrast even at wide-open aperture.
  • Autofocusing is performed by two Linear Ultrasonic Motors that provide very fast, precise, and quiet operation.
  • Its size, shape, and grip have been ergonomically designed for enhanced stability and comfortable use.
  • Weather sealing and a robust all-metal design provide dust and moisture resistance with a luxurious look and excellent durability.


To maintain your safety and prevent damage to the lens, please fully familiarize yourself with the following:

  • Do not look directly at the sun through the lens as it may seriously impair your vision.
  • Do not apply excessive force when attaching the lens to the camera as it may cause damage to the lens or your camera.
  • The lens is a precision optical product, so dropping or excessive impact may cause product failure.
  • Attach or detach the lens only while the camera is turned off.
  • Be careful not to touch or contaminate the gold contacts on the mount as it can adversely affect communication with the camera.
  • Protect the lens from water, high humidity, and excessive heat.
  • Always store the lens with the lens cap on in a dry and well-ventilated location out of direct sunlight. Direct sunlight passing through the lens could become concentrated enough to cause a fire.
  • Avoid subjecting the lens to drastic temperature changes such as moving from a very cold outdoor location to a warm indoor location. This can cause moisture in the air to condense inside or on the outside of the lens and lead to failure or mold production. Before taking the lens indoors from a cold outdoor location, put the lens in a plastic bag or sealed camera bag and remove it only when the lens has warmed up to room temperature.


  • When mounting the lens make sure that it clicks in place otherwise it may detach and cause damage or injury.Rokinon IO85AF-E 85mm Auto Focus Lens-FIG 4

Sony mirrorless interchangeable lens cameras offer various methods of focusing. For detailed information regarding the available focus mode settings for your particular model, refer to the instruction manual of your camera. Functions supported by the lens may vary.

  • AF-S (Single-Shot AF): Autofocus operates when the shutter button is pressed halfway down. Once the subject is in focus, the focus is locked. It is suitable for shooting motionless subjects such as landscapes or snapshots.
  • AF-C (Continuous AF): Autofocus continues to operate and keeps adjusting the focus while the shutter button is pressed and held halfway down. It is suitable for shooting moving subjects such as sports.
  • AF-A (Automatic AF): When the shutter button is pressed halfway down, the camera automatically recognizes whether the subject is moving or not, and switches the AF mode between AF-S and AF-C accordingly. Use this mode to shoot various subjects at the same time, or to avoid switching the AF mode manually.
  • DMF (Direct Manual Focus): Allows you to use manual focus and autofocus in combination. Press the shutter button halfway down to focus automatically. Keep the shutter button halfway down and rotate the focusing ring on the lens to fine focus.
  • MF (Manual Focus): Allows you instead of the camera to adjust the focus by rotating the focusing ring on the lens. MF is effective when autofocus does not work well such as in macro shooting

Mounting a Filter

The lens is equipped with a non-rotating filter mount on the front of the lens that accepts 77mm size Filters. The product specifications and design are subject to change without notice. Only one filter typically should be mounted at one time.  If two or more filters are mounted at the same time, vignetting may occur.

Lens Hood

The supplied hood is designed specifically for the Rokinon AF 85mm F1.4 lens for optimum effectiveness. It should be used at all times to help prevent contrast-reducing flare and for added protection.

  • To mount the hood, align the white index mark (dot) of the hood with the white hood index mark (dot) of the lens and rotate the hood clockwise until you hear and feel it click in place. – The minimum focus is the distance from the image sensor to the object.
  • To remove the hood, grasp it firmly and turn counter-clockwise.Rokinon IO85AF-E 85mm Auto Focus Lens-FIG 2
