Focusing

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 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.

Lens Hood

The supplied petal-shaped hood is designed specifically for the Rokinon AF 50mm F1.4 lens for optimum effectiveness. It should be used at all times to help prevent contrast-reducing flare, provide better contrast, 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 hood is mounted correctly when the short “petals” are on the left and right and the longer petals on the top and bottom. If the hood is not mounted correctly it might become damaged or create vignetting in which the petals of the hood can be seen or darken the edges of the image.
• To remove the hood, grasp it firmly near its base and turn counterclockwise
• You can store the hood in its reverse position for easy transport. Reverse the hood so that it covers the lens barrel and again 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.
• Please note that the lens hood might block the light from small-sized flash units causing a shadow at the bottom of the image.

Product specifications

• The minimum focus is the distance from the image sensor to the object.
