50-200mm F4-5.6 DC OS HSM
This is a fisheye lens for digital
cameras with an angle of view
across the diagonal of 180° when
used with a Nikon camera (or 154°
with a Sigma camera or 167° with
a Canon camera). This lens allows
photographers to shoot creative
images by taking advantage of the
acute perspectives that are invisible
to the human eye and the image
distortion specific to fisheye lenses.
A maximum magnification of 1:3.3
and minimum focusing distance
of 13.5 cm (5.3 inches) allows it to
focus on subjects that are only 1.8
cm away. It has a specially designed
fixed hood and a Super Multi-
Layer Coating to cut down on the
occurrence of flare and ghosting and
display excellent image quality.
Equipped with Sigma's own Camera
Shake Compensation OS(Optical
Stabilizer) System, this is a compact
lens with a maximum
diameter of 74.4mm and length
of 102.2mm. It makes handheld
shooting easy at all focal lengths.
Designed for portability, it's
compact design makes it perfect for
photographers who want a small,
lightweight telephoto lens. High-
quality images are obtained by using
SLD(Special Low Dispersion) glass
and an inner focus system. The
Super Multi-Layer Coating reduces
the occurrence of flare and ghosting
and also ensures high-contrast
images throughout the entire focal
range. The HSM makes fast AF
speeds and quiet shooting a reality.
This is a large-aperture standard
lens for digital cameras, with a fast
F1.4 aperture that makes handheld
shooting in dim light possible.
Using the out-of-focus effects
of a shallow depth of field, the
photographer can enjoy shooting
snapshots, portraits, or landscapes.
ELD (Extraordinary Low Dispersion)
glass, SLD (Special Low Dispersion)
glass, and aspherical lens elements
are used to obtain the best possible
correction for chromatic aberration
and sharp image quality across the
entire focusing range from 40 cm
to infinity. The HSM model makes
fast AF speeds and quiet shooting
a reality, and includes full-time
manual focus override.
The circular fisheye lens creates
a circular image when used on
a digital SLR camera. It's an
ideal lens for landscapes and
panoramic photography. Because
of its equisolid angle projection
system, the lens can be used for
scientific applications. It has a
minimum focusing distance of 13.5
cm (5.3 inches) and a maximum
magnification of 1:6. SLD (Special
Low Dispersion) glass is used for
superior correction of chromatic
aberration, and a Super Multi-Layer
Coating is used to minimize the
occurrence of flare and ghosting.
The HSM model makes fast AF
speeds and quiet shooting a reality,
and includes full-time manual focus
override.
