What you should know to choose the right lens for your needs.
Accessory for all SIGMA Art, Contemporary and Sports
By connecting a SIGMA Art, Contemporary, or
Sports lens to a computer with the SIGMA USB
DOCK, photographers can update the lens rmware
and adjust focus position and other parameters.
Exclusive SIGMA Optimization Pro software makes
customization easy.
Note1: It is not compatible with Sony E-mount,
Micro Four Thirds
System
and FUJIFILM X Mount.
Note2: Scope of adjustment varies depending on specications of

SIGMA OPTIMIZATION PRO
Offering outstanding water-repellent, oil-repellent,
and antistatic functionality, SIGMA’s WR filters
make both shooting and maintenance easier. The
UV type significantly reduces UV radiation, which
can have a negative effect on photographic images.
The CIRCULAR PL (polarizing) type reduces reec-
tions and glare from subjects while enhancing color
contrast. Available in two versions, the PROTECTOR
type serves as a highly effective way to protect a
lens. This outstanding lter lineup is available in a
wide range of sizes.
These products represent the highest level of
protection in the SIGMA Filter series. Featuring
the new material Clear Glass Ceramic, these light-
weight lters are highly resistant to both scratches
and breakage. Their capacity to repel water and
oil is excellent, and the coating is antistatic for
outstanding dust-resistence. This specication is
ready for even the toughest shooting conditions.
Note: The 46mm drop-in lter designed for placement at the
rear of the lens has a specication exclusive to each lens.

Angle of view
Angle of view is determined by the focal length of the
lens and the size of the image (sensor or lm format)
frame. With a given image size, changing the focal
length will change the area of the scene that appears
in the photographic image. Expressed in degrees,
this area of the scene is the angle of view. The longer
the focal length, the smaller the angle of view and
the greater the image magnication.
F-number
The aperture controls how much light can be gath-
ered by the lens. The F-number (F2.8, F4, F5.6, etc.)
is the ratio of the focal length to the entrance pupil
diameter. The lower the F-number, the brighter the
lens; the higher the F-number, the darker the lens.
The benets of a low F-number include the ability to
use higher shutter speeds, excellent bokeh effects,
and a bright viewnder image.
Perspective
Changing the focal length of the lens changes the
apparent distance in an image between the subject
and its background. This optical effect is called per-
spective. For example, a wide-angle lens causes the
background to seem far away and vast, emphasizing
the distance between it and the subject. In contrast,
a telephoto lens with a long focal length will cause
the background to appear close to the subject, de-
emphasizing perspective. Further, a wide-angle lens
can bring the surroundings of the subject into the
shot, while a telephoto lens can effectively isolate
the subject. By leveraging the power of perspective
in this way, one may greatly increase the range of
photographic expression.
Depth of eld
When you focus on a subject, some objects in front of
and behind the subject will also be in focus. “Depth
of eld” refers to the depth of this foreground-back-
ground distance. A smaller lens aperture (higher
F-number) increases depth of field, bringing more
F2.8
F22
foreground and background into focus. A larger ap-
erture (lower F-number) isolates your subject with
a blurred bokeh foreground and background. Focal
length is also a factor. Telephoto lenses have less
depth of eld, whereas wide-angle lenses have more.
Minimum focusing distance
The distance between the lm surface or image sen-
sor surface of an SLR or mirrorless camera and the
subject is known as the shooting distance. The short-
est shooting distance at which the camera can focus
on the subject is the minimum focusing distance.
Working distance
The distance between the front of the lens and the
subject.
Magnication ratio
The ratio of the size of the impression of a subject
captured on the image sensor or film surface to the
actual size of the subject. For example, when a 4cm
long subject appears as 1cm long on the image sensor
or lm surface, the magnication is described as 1:4.
If it appeared as 4cm long on the image sensor or lm
surface, the magnification would be 1:1. The maxi-
mum magnication ratio shown in the main specica-
tions describes the largest possible magnication of
the subject by that particular lens.
