Notes on Use
WARNING
-
Do not point the lens directly at the sun or any strong light source. Internal malfunction of the camera body and lens, smoke, or a fire may result due to the effect of light focusing.
If circumstances necessitate leaving the lens in sunlight, be sure to attach the lens caps. -
When shooting against the sun, keep the sun completely out of the angle of view. Otherwise, solar rays may be concentrated at a focal point inside the camera, causing smoke or a fire. Keeping the sun slightly out of the angle of view may also cause smoke or a fire.
-
Do not point the lens toward the sun when carrying the lens.
Sunlight may converge through the lens and potentially cause a malfunction. -
This lens is not water-proof, although designed with dust-proofness and splash-proofness in mind. If using in the rain etc., keep water drops away from the lens.
-
If the lens alone is shaken or if a camera with the lens attached is shaken while the camera is turned off, an internal component of the lens may rattle. This, however, does not indicate a malfunction.
-
In addition, while you carry around the lens, your movement may cause the internal lens groups to shake. This, however, does not affect the performance of the lens groups.
-
When carrying a camera with the lens attached, firmly grasp the body of the lens.
-
Using this unit with products from other manufacturers may affect its performance, leading to accidents or malfunction.
Precautions on using a flash
- You cannot use a built-in camera flash with this lens.
Vignetting
When using the 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.

C Using the Tripod
When using a tripod, attach it to the tripod collar of the lens, not to the
tripod receptacle of the camera.
To change vertical/horizontal position
Loosen the tripod collar ring-locking knob on the tripod collar (1) and rotate
the camera either direction. The camera can be quickly switched between
vertical and horizontal positions while maintaining stability when using a
tripod.
- Gray indexes (tripod collar ring indexes) are located at 90° intervals on the collar ring. Align a gray index on the tripod collar ring with the gray index (tripod collar ring index) on the lens to adjust the camera position precisely (2).
- Tighten the tripod collar-locking knob firmly after the camera position is set.
- The tripod collar ring may hit the camera body or accessory when rotated, depending on the camera or accessory model. For more information on compatibility with cameras and accessories, visit the web site of Sony for your area. Detaching and attaching the tripod collar
Detaching the tripod collar
- If you detach the tripod collar without removing the lens from the camera, the tripod collar may hit the camera body or accessory. We recommend you remove the lens from the camera before detaching the tripod collar.
- When removing the tripod collar from the tripod collar ring, the tripod screw holes become exposed on the tripod collar ring. Do not attach a tripod or monopod to the tripod screw hole. If you do that, you will damage the screw hole. Then you will not be able to attach the tripod collar to the tripod collar ring.
Attaching the tripod collar
- Slide the tripod collar to the mount of the tripod collar ring until it clicks.
- Rotate the tripod collar-locking knob clockwise firmly to set it.
• Be sure that the tripod collar-locking knob is set firmly. If the tripod collar-locking knob is not set firmly, the lens may fall off the tripod collar.
D Attaching the Lens Hood
It is recommended that you use a lens hood to reduce flare and ensure maximum
image quality.
Align the red line on the lens hood with the red line on the lens (lens hood
index), then insert the lens hood into the lens mount and rotate it clockwise
until it clicks into place and the red dot on the lens hood is aligned with
the red line on the lens.
- If the lens hood is not rotated until it clicks into place, there is a possibility that a shadow appears on captured images or the lens hood falls off.
- If the flash light is partially blocked by the lens hood, a shadow may appear at the bottom of captured images. In such a case, remove the lens hood.
- When storing, fit the lens hood onto the lens backwards.
F Focusing
- The focus mode switch of this lens does not function with some camera models.
For further information on compatibility, visit the web site of Sony in your area, or consult your dealer of Sony or local authorized service facility of Sony.
To switch AF (auto focus)/MF (manual focus)
The focus mode can be switched between AF and MF on the lens.
For AF photography, both the camera and lens should be set to AF. For MF
photography, either or both the camera or lens should be set to MF.
To set the focus mode on the lens
Slide the focus mode switch to the appropriate mode, AF or MF (1).
- Refer to the camera manuals to set the focus mode of the camera.
- In MF, turn the focusing ring to adjust the focus (2) while looking through the viewfinder, etc.
- With the full-time direct manual focus switch slid to ON, the focus mode automatically switches to MF when the focusing ring is rotated, regardless of the AF mode setting and the focus adjustment (3).
To use a camera equipped with an AF/MF button
- By pressing the AF/MF button during AF operation, you can temporarily switch to MF.
- Pressing the AF/MF button during MF operation lets you temporarily switch to AF if the lens is set to AF and the camera to MF.
F Using SteadyShot
SteadyShot switch
• ON:
Compensate for camera shake.
• OFF:
Does not compensate for camera shake. We recommend setting the SteadyShot
switch to OFF when shooting with a tripod.
SteadyShot mode switch
Set the SteadyShot switch to ON, and set the SteadyShot mode switch.
• MODE1:
Compensate for normal camera shake.
• MODE2:
Compensate for camera shake when panning moving subjects.
• MODE3:
Compensate for camera shake to minimize framing disturbances. This helps you
to keep up with fast and irregularly moving subjects for photography, for
example, in sports games.
G Using the Focus Hold Button(s)
The focus hold button of this lens does not function with some camera models.
For further information on compatibility, visit the web site of Sony in your
area, or consult your dealer of Sony or local authorized service facility of
Sony.
Press the focus hold button in AF to cancel AF. The focus is fixed and you can
release the shutter on the fixed focus. Release the focus hold button while
pressing the shutter button halfway to start AF again.
H Switching Focus Range
(AF range)
The focus-range limiter enables you to reduce the AF time. This is useful when
the subject distance is definite.
Slide the focus-range limiter to select the focus range.
- FULL: You can adjust the focus from the minimum focusing distance to infinity.
- – 6m: You can adjust the focus from 6.0 m (19.7 feet) to infinity.
I Power focusing
You can rack the focus at a consistent pace by rotating the function ring.
This focusing is useful for smooth rack focusing, for example, during video
shooting. Rotate the function ring.
- Rack focusing is performed at a consistent pace in the same direction as the focusing ring is rotated.
- Rack focus speeds can be selected in accordance with rotation angles of the focusing ring.
- Power focusing is available in any focus mode: AF, MF, or DMF.
J Changing the drop-in filters
The normal filter is attached to the lens at your purchase.
The filter is a component of the optical lens system. Be sure to attach either
one of the filters before photographing: the normal filter or the circular
polarizing filter.
To replace the drop-in filter
-
Push down and turn the filter-holder knob counterclockwise by 90° toward the lens front (1).
• When the filter-holder knob is turned by 90°, the flat cut-off surface of the knob faces toward the lens front. -
Lift the filter-holder straight up (2).
-
Replace the filter (3).
-
Insert the filter-holder into the lens barrel with the flat cut-off surface of the filter-holder knob facing toward the lens front.
-
Push down and turn the filter-holder knob clockwise by 90° to lock the filter-holder.
When the filter-holder knob is locked, the index bar on the flat cut-off
surface of the filter-holder knob is aligned with the index bar on the filter-
holder (4).
After replacement of the drop-in filter, make sure that the filter-holder knob
is properly locked.
To use the VF-DCPL1 Drop-in Circular Polarizing Filter (sold separately)
(See illustration J-a)
1 Adjust the focus precisely while looking through the viewfinder, etc.
2 Rotate the adjustment ring on the drop-in circular polarizing filter-holder
while looking through the viewfinder, etc., to adjust the polarization degree
for photographing.
• The circular polarizing filter can reduce or eliminate unwanted reflections
(polarized light) from nonmetallic surfaces of water, glass, windows, shiny
plastics, ceramics, paper, etc. It also helps you get good contrast when
taking photos of blue sky.
• Generally, reflected light (polarization) should be minimized in
photography. However, you can adjust the polarizing degree for the desired
effect as well.
• The amount of light reaching the image sensor decreases. If your camera is
set to manual exposure mode and you are using a commercially available
exposure meter, or if your camera is set to manual exposure mode and you are
using the Manual Flash Control function available on some external flash
units, adjust the exposure compensation by opening the aperture by 1 to 2
stops to the + side.
K Storing the lens in the case
Fully open the zipper of the case all the way to the bottom and place the lens
into the case as illustrated.
After placing the lens in the case, hang the strap around the lens and be sure
to secure the strap to the case using the hook and loop fastener.
L Attach the hook and loop fastener to a position on the case where the lens
cannot slip through the strap. Attaching the lens strap
Before carrying around the lens, attach the lens strap to the lens.
- To prevent the lens from dropping, be sure to attach the lens strap properly so that the lens strap will not come loose from the lens.
- When carrying around the camera with the lens attached, be sure to grasp the lens strap on the lens, not the one on the camera.
