About Rokinon

Rokinon is a brand known for manufacturing camera lenses and other optical equipment. It is part of the Samyang Optics Company, a South Korean optical equipment manufacturer. Rokinon lenses are often praised for their affordability and good optical quality, making them popular among photographers and videographers, especially those on a budget.


  • An inconspicuous size, a 9.5” minimum focusing distance, and a substantial wide angle of view make it perfect for travel, astrophotography, stealthy street shooting, and landscapes.
  • It will provide optimal quality still images and video with both Sony Full Frame and APS-C image sensor cameras. For Sony Alpha APS-C camera users the lens is equivalent to approximately 36mm to provide a more moderate wide-angle view.
  • The AF (autofocus) is optimized for fast and precise focus detection with mirrorless cameras.
  • Seven elements in seven groups, three Aspherical lenses, two high refractive lenses plus Ultra Multi Coating are utilized to minimize aberrations and increase sharpness for impressive image quality.
  • The IF (Internal Focus) design prevents both changes in length and front element rotation for easy use with polarizing and other filters where positioning must be maintained.


  • 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 outdoors 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.




  • It is extremely important before cleaning to dust off the lens surface using a lens blower or a soft brush to remove any foreign particles or grit that could scratch the lens.
  • Using a clean microfiber lens cloth, gently wipe the lens in a circular motion from the center outwards towards the edges of the glass.
  • If stubborn spots remain, put only one or two small drops of ethanol or reputable lens cleaner on the microfiber cloth and repeat the circular cleaning process. DO NOT USE AN ORGANIC SOLVENT SUCH AS PAINT THINNER, ALCOHOL, OR BENZENE.

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.

  • 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 adjust 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.
