DC LENS
These are special lenses that are designated for digital cameras because the lens
image circle is designated to correspond to the size of the image sensors of most
digital SLR cameras. The specialized design gives these lenses the ideal properties
for digital cameras.
◆ An image sensor element larger than those corresponding to APS-C cannot be
used in digital cameras or 35mm SLR cameras. If such an element is used
vignetting will occur on the picture surface.
◆ If you use SD14, SD10 or SD9 digital cameras, corresponding angle of view will be
51mm.
ATTACHING TO CAMERA BODY
When this lens is attached to the camera body it will automatically function in the
same way as your normal lens. Please refer to the instruction booklet for your
camera body.
◆ On the lens mount surface, there are a number of couplers and electrical contacts.
Please keep them clean to ensure proper connection. To avoid damaging the lens,
be especially sure to place the lens with its front end down while changing the lens.
◆ Many accessories such as rear mounted teleconverters, extension tubes, etc., are
specially made for designated lenses. Before you purchase such accessories,
please check your Sigma lens to determine that it is compatible and that the
accessories will function properly with it.
SETTING THE EXPOSURE MODE
The sigma lens functions automatically after mounting to your camera. Please,
refer to the camera instruction book.
FOCUSING
《FOR SIGMA AF, CANON AF, NIKON AF AND FOUR THIRDS》
This lens features Sigma’s built-in Hyper Sonic Motor (HSM). The HSM enables
quick and quiet autofocusing.
For autofocus operation, set the focus mode switch on the lens to “AF” position
(fig.2) (for Nikon AF, select the autofocus mode on your camera body) (For
Four-Thirds, select the autofocus mode on your camera body and set the focus
mode switch on the lens to the “AF” position).
If you wish to focus manually, set the focus mode switch on the lens to the “M”
position.
(for Nikon AF, select the manual focus mode on your camera body as you would do
normally) (For Four-Thirds, select the manual focus mode on your camera body and
set the focus mode switch on the lens to the “M” position). You can adjust the focus
by turning the focus ring.
◆ This lens also permits manual focusing even in the autofocus mode. With the
camera set to the One-Shot AF (AF-S) mode, you can adjust focus manually after
the lens autofocus (and stops), while the shutter button is pressed halfway. (In
the case of Four-Thirds fitting, the setting method varies depending on the camera
body. Please follow the instruction manual of your camera body.)
◆ 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 contact.
Special allowance is made for this at the infinity setting.
《FOR SONY AF AND PENTAX AF》
For autofocus operation, set the camera’s focus mode to AF.
If you wish to focus manually, set the camera’s focus mode to “MF” and adjust the
focus by turning the focus ring.
◆ To avoid damaging AF mechanism, please do not turn the focus ring manually
while in the autofocus mode.
◆ 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 contact.
Special allowance is made for this at the infinity setting.
LENS HOOD
A bayonet type detachable hood is provided with the lens. This lens hood helps to
prevent flare and ghosted images caused by bright illumination from outside the
picture area. Attach the hood and turn clockwise until it stops rotation. (fig.3)
◆ When taking photographs using the built-in flash, it is advisable to remove the lens
hood so as to avoid cutting off any of the flash output, which could cause a
shadow in the picture.
◆ In order to place the lens and hood into the storage case, you must first remove
the hood, then replace it on the lens in the reverse position. (fig.4)
FILTER
◆ Only one filter should be used at the time. Two or more filters and/or special
thicker filters, like a polarizing filter, may cause vignetting.
◆ When using a polarizing filter with AF camera, use the “circular” type.
BASIC CARE AND STORAGE
◆ Avoid any shocks or exposure to extreme high or low temperatures or to humidity.
◆ For extended storage, choose a cool and dry place, preferably with good
ventilation. To avoid damage to the lens coating, keep away from mothballs or
naphthalene gas.
◆ Do not use thinner, benzine or other organic cleaning agents to remove dirt or
finger prints from the lens elements. Clean by using a soft, moistened lens cloth
or lens tissue.
◆ This lens is not waterproof. When you use the lens in the rain or near water, keep
it from getting wet. It is often impractical to repair the internal mechanism, lens
elements and electric components damaged by water.
◆ Sudden temperature changes may cause condensation or fog to appear on the
surface of the lens. When entering a warm room from the cold outdoors, it is
advisable to keep the lens in the case until the temperature of the lens approaches
room temperature.
