Sony a200 Instruction Manual page 165

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. The focus signal in the
viewfinder indicates the current condition of the focus.
Depth-of-field scale (50mm F1.4)
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 Digital Single Lens Reflex Cameras equipped with an
APS-C sized image sensor.

Attaching/detaching the lens
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.
Cleaning the lens
• Do not touch the surface of the lens directly.
• If the lens gets dirty, brush off dust with a lens blower and wipe with a soft,
clean cloth (Cleaning Cloth KK-CA (optional) is recommended).
• Do not use any organic solvent, such as thinner or benzine, to clean the lens or
the camera cone.
To attach the lens (See illustration
m-ITJ.)
1
Remove the rear and front lens caps and the camera body
cap.
• You can attach/detach the front lens cap in two ways, (I) and (2). When you
attach/detach the lens cap with the lens hood attached, use method (2).

• When using a built-in camera flash, make sure to remove the lens hood to avoid
blockage of the flash light.
• 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.
• When slOring, tum over the lens hood and place it onlO the lens backwards.
Rotate the zooming ring to the desired focal length.
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 until it clicks.
24-105mm F3.5-4.5:
Align the red lines on the lens hood and the lens. Turn the hood
clockwise until the red line on the lens meets the red dot on the
hood and it clicks into place.
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.

Designs and specifications are subject to change without notice.
• This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a flash for AD!.
• 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.
Specifications
Condensation
[f your lens is brought directly from a cold place to a warm place,
condensation may appear on the lens. To avoid this, place the lens in a plastic
bag or something similar. When the air temperature inside the bag reaches
the surrounding temperature, take the lens out.
• Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby
Object, it may cause a fire. If circumstances necessitate leaving the lens in direct
sunlight, be sure to attach the lens cap.
• Be careful not to subject the lens to mechanical shock while attaching it.
• Always place the lens caps on the lens when storing.
• Do not keep the lens in a very humid place for a long period of time to prevent
mold.
• Do not hold the camera by the lens part extended for focusing, etc.
• Do not touch the lens contacts. If dirt, etc., gets on the lens contacts, it may
interfere or prevent the sending and receiving of signals between the lens and the
camera, resulting in operational malfunction.
Precaution for flash use
With certain of lenslflash combinations, the lens may partially block the light
of the flash, resulting in a shadow at the bottom of the picture. 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.
Vignetting
• When you use lens, the comers of the screen become darker than the center. To
reduce this phenomena (called vignetting), close the aperture by I to 2 stops.
• With certain of lens/filter combinations, the frame of the filter may block the
incident radiation, which may significantly lower the light intensity. Take lest
photographs at different aperture sellings for best results. (24-1 05mm F3.5-4.5
