There are five focus methods for SONY αinterchangeable-lens
cameras. (※ This may vary according to the camera model.)

- AF-S (Single shooting AF): The focus is adjusted automatically in the

camera.

- AF-A (Automatic AF): The camera switches to single shooting AF or

continuous AF mode automatically according to the movement of a
subject.

- AF-C (Continuous AF): The focus is adjusted continuously in the

camera.

- DMF (Direct manual focus): Manual fine adjustment is available after

automatic focusing.

- MF (Manual focus): The focus is adjusted manually.

For detailed content regarding the focus mode setting, refer to the
instruction manual of the camera.

The hood blocks unnecessary light and protects the front surface of the
lens from rain, snow or dust.

- Align the mount position index indicated on the hood with the hood

index (white) indicated on the lens, rotate the hood clockwise until a
clicking sound occurs and the hood is fixed.

- You can store the hood by mounting it on the lens in the opposite

direction. 

※ Caution: If the hood is not mounted correctly, vignetting may occur.

(Vignetting: A reduction of an image's brightness at the periphery
compared to the image center occurring when the angle of the lens’
view is covered)

A filter can be mounted on the filter mounting screw at the front of the

lens.

- Only one filter can be mounted.

※ If two or more filters are mounted at the same time, vignetting may

occur.

- Check if the filter size is compatible with the lens (refer to “Product

specifications”), and then mount it at the front of the lens.
