Attaching/detaching the lens
To attach the lens (See illustration
–
.)
1
Remove the rear and front lens caps and the camera body cap.
You can attach/detach the lens front cap in two ways, (1) and (2). When
you attach/detach the lens cap with the lens hood attached, use method (2).
2
Align the orange index on the lens barrel with the orange index
on the camera (mounting index), then insert the lens into the
camera mount and rotate it clockwise until it locks.
Do not press the lens release button on the camera when mounting the lens.
Do not mount the lens at an angle.
To remove the lens (See illustration
–
.)
While pressing and holding the lens release button on the camera,
rotate the lens counterclockwise until it stops, then detach the lens.
Attaching lens hood
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.
75-300mm F4.5-5.6, 50mm F1.4:
Fit the hood into the mount on the end of the lens barrel and rotate
the hood clockwise.
20mm F2.8:
Align the red line on the lens hood with the red dot on the lens (Lens
hood index), and rotate the lens hood clockwise until it stops.
If a marking (red line, red dot, etc.) is provided, attach the lens hood properly.
Otherwise, the lens hood may interfere with the desired effect or may appear in
pictures. (20mm F2.8 only)
When storing, turn over the lens hood and place it onto the lens backwards.
Zooming (75-300mm F4.5-5.6)
Rotate the zooming ring to the desired focal length.
Focusing
When using the auto focus, the camera focuses the lens automatically. When
focusing manually, set your camera to the manual focus and rotate the
focusing ring while looking through the viewfinder, etc.
Depth-of-field scale (50mm F1.4/20mm F2.8)
When focus is set on a subject, anything at that same distance will appear
sharp, and anything within a certain range before and beyond the subject will
also appear in focus; this is called depth of field. Depth of field depends on
the subject distance and aperture you choose and is indicated by the lines on
the depth-of-field scale corresponding to the aperture.
The depth-of-field scale is for 35mm-format cameras. The depth-of-field is
shallower when you use Interchangeable Lens Digital Cameras equipped with an
APS-C sized image sensor.
English
You will find information on using each lens in this manual. Precautions
common to lenses, such as notes on use will be found in “Precautions
before using” on a separate sheet. Be sure to read both documents before
using the lens.
This manual is for use with several different lenses.
This lens is designed for A-mount, which can be used on Sony
α cameras.
Notes on use
When using this lens with an E-mount camera, attach a separately sold Mount
Adaptor. Do not attach the lens directly to the E-mount camera or you may
damage both.
When you carry the camera with the lens attached, make sure to hold both the
camera and the lens steadily.
Do not hold by any part of the lens that protrudes when zooming or focusing.
Precaution for flash use
When using a built-in camera flash, make sure to remove the lens hood and
shoot from at least 1m (3.3 feet) away from your subject. With certain of
lens/flash combinations, the lens may partially block the light of the flash,
resulting in a shadow at the bottom of the picture.
Vignetting
When you use lens, the corners of the screen become darker than the center.
To reduce this phenomena (called vignetting), close the aperture by 1 to 2
stops.

The value for the equivalent 35mm-format focal length is based on Interchangeable Lens Digital Cameras equipped with an APS-C sized image sensor.
*
2
The value of angle of view 1 is based on 35mm-format cameras, and that of angle of view 2 is based on Interchangeable Lens Digital Cameras equipped with an APS-C sized
image sensor.
*
3
Minimum focus is the distance from the image sensor to the subject.
This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by employing a flash for the process. (75-300mm F4.5-5.6,
50mm F1.4 only)
Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at infinity.
