Fisheye Sigma 10 mm F2.8 EX DC HSM Fisheye
This gives creativity another piece of freedom. The Sigma 10mm
fisheye lens is designed for users with an unusual view and for
experimental photographers. Panoramic photography is also not
unaffected by this lens. You can quickly create high-quality
all-round views. The enormous depth of field allows you to take
impressive close-up s that capture the subject, as well as
the subject's surroundings The HSM (Hyper Sonic Motor) gives you
fast, silent autofocus that you can manually intervene at any
time. The fisheye lens is equipped with a fixed tulip-shaped lens
hood to prevent stray light.
The Sigma Fisheye 10 mm F2.8 EX DC HSM offers an extremely large
diagonal viewing angle of up to 180° in the Nikon version (Sigma
154° and Canon 167°). It is optimized for use on digital SLR
cameras with image sensors in APS-C format and allows the extreme
perspective and distortion typical of fisheye lenses. The high
light intensity of F2.8 delivers a bright viewfinder image and
allows shooting in poor lighting conditions. With the small
minimum distance of only 13.5 cm, s up to a scale of 1:3.3
are possible, with the object only 1.8 cm in front of the front
lens. The Sigma SML (Super Multi Layer) coating minimises
reflections and ghosting and ensures a balanced colour balance.
The built-in lens hood prevents stray light from entering the
side. On the back of the lens, a filter drawer allows you to
insert gelatin filters.
- Unique design.
Exclusive quality, non-slip design, elegant finish - these are
the features of our professional rail. The EX symbol
characterizes our sophisticated lens series. In addition to the
high quality standard, these products are characterised by
exclusive focal length ranges and high light intensities. The
excellent performance features of Sigma EX lenses, uncompromising
design, perfect handling and excellent durability meet the
demands of photographers at the highest level. EX lenses - the
better choice.
- APS-C sensor suitable. Example image of 10 mm F2.8 EX DC HSM

First of all, the coating technology and the construction of the
DC lenses, whose calculations are based on digital demands,
largely prevent light reflections from the sensor on the backward
objective lens. In addition, the DC lenses offer impressive image
quality despite their low weight and compact size, which meets
the demands of digital SLR cameras. These lenses are limited to
the angle of view that is only used by most DSLR cameras anyway –
to the angle of view of the cameras with a sensor size in the
so-called APS-C format. The sensors of most digital SLR cameras
are smaller than the 35mm film with its 24x36mm format and have
the dimensions of the APS-C film format. Therefore, you cannot
use the DC lenses on a full-frame digital camera or an analogue
film camera. They inevitably received shadows in the corners of
the picture. By limiting the image angle to this APS-C format, it
is possible to achieve a considerable image performance with
reasonable design effort. The less complex design affects the
size and weight of the DC lenses. The lower effort ensures
significant cost savings, which we pass on to our customers. With
our DCs you get powerful lenses at extremely attractive prices.
When DC series lenses are used on 35mm SLR cameras or digital
cameras whose image sensors are larger than APS-C format,
vignetting occurs in the image.
- One motor with speed.
HSM lenses use a motor driven by ultrasonic waves. This
technology gives you a very fast, accurate and almost silent mode
of automatic focus. Two different types of HSM ultrasonic drive
are used in our lenses. On the one hand, the HSM ring motor,
which is mainly installed in the high-quality EX lenses. This HSM
drive allows you to manually intervene in the AF operation at any
time. On the other hand, an HSM micromotor is mainly used in
compact lenses, the so-called all-round zoom lenses.
Manual intervention in AF operation is not possible.
MTF chart - please click on image to MTF modulation
transfer function.
The MTF (modulation transfer function) is one of the measuring
methods with which the performance of a lens and its contrast
behavior can be determined at different spatial frequencies. The
horizontal axis expresses in millimetres the distance of the
centre of the image to the edge of the picture, the vertical axis
expresses the contrast value (highest value is 1).
The information for 10 lines/mm reflects the contrast behavior of
the lens (red lines), the values for 30 lines/mm express the
resolution (green lines), each with the aperture open. Lines that
run parallel to the image circle diameter are called sagittal
lines (solid line), transverse lines are called tangential lines
(dashed line).

Designed for use with Canon digital SLR cameras equipped with
APS-C size image sensors, the Sigma 10mm f/2.8 fisheye lens
offers a uniquely exaggerated and distorted close-up perspective
that's perfect for arty, off-kilter s. This Canon version
offers an impressive 167-degree diagonal angle of view, along
with a minimum focusing distance of 5.3 inches and a maximum
magnification ratio of 1:3.3. As a result, subjects can sit as
close as 0.7 inches from the lens's front element, making the
lens ideal for extreme close-up s and photos with a large
depth of field. The lens also includes a Hyper Sonic Motor (HSM)
that provides fast and quiet autofocusing, with a full-time
manual focus override via a simple twist of the focus ring. And
thanks to the lens's integral hood and super multilayer coating,
you can easily block out extraneous light while minimizing flare
and ghosting. Supplied with a gelatin filter holder at the rear,
the 10mm lens carries Sigma's one-year warranty.
