FOCUSING AND ZOOMING
This lens features Sigma’s built-in Hyper Sonic Motor (HSM). The HSM
enables quick and quiet autofocusing.
SIGMA AF and CANON AF
For autofocus operation, set the focus mode switch on the lens to the “AF”
position (fig.2). If you wish to focus manually, set the focus mode switch on the
lens to the “M” position. You can adjust the focus by turning the focus ring.
NIKON AF, PENTAX AF, and SONY
For autofocus operation, set the camera to AF mode and set the focus mode
switch on the lens to the “AF” position (fig.2). If you wish to focus manually, set
the focus mode switch on the lens to the “M” position. You can adjust the focus

◆ Please refer to camera’s instruction manual for details on changing the
camera’s focusing mode.

camera bodies which support motors driven by ultrasonic waves such as
HSM. AF will not function if the camera body does not support this type of
◆ This lens also permits manual focusing even in the autofocus mode. With
the camera set to the One-Shot AF (AF-S) mode, it is possible to manually
override the autofocus while the shutter release button is pressed halfway.
◆ When operating this lens in manual focus mode, it is recommended that
correct focus be confirmed visually in the viewfinder rather than relying on
the distance scale. This is due to possible focus shift resulting from
extreme changes in temperature which cause various components in the
lens to expand and contract. Special allowance is made for this at the
Rotate the Rubber grip on the zoom ring to the desired position.
ZOOM LOCK SWITCH

when the lens is tilted down. Please set zooming ring to 150mm and set the

motion or shake.
◆ Please do not use Optical Stabilizer in the following situations.
▪ When the lens is mounted on a tripod. ▪ Bulb (long time exposure).

you are not using Optical Stabilizer, please turn OFF the OS switch, in order
to prevent consumption of a battery.
◆ Be sure to turn of OS switch to OFF position, before attaching or detaching

exposure value. Never remove the lens or remove the camera’s battery
while the image stabilizer is operating, you could damage the lens.
Although the viewfinder image may appear to shake immediately after
shooting and at the start of the flash charge cycle of the built-in flash of the
camera etc., it will not cause any effect on pictures.
◆ If the camera power is turned off or lens is detached while the Optical
Stabilizer function is in operation, the lens may emit a chattering noise, but
this is not a malfunction.

following table. When using this lens with other camera models not listed in
the following table, please set the OS Switch to OFF position to cancel the
Optical Stabilizer function.
