Introducing the flagship lens of the Sports line
Covering all the essence. Portable, durable and of a high-standard – A Masterpiece of
hyper-telephoto lens.Photographers typically choose a prime lens when they require top image
quality. However, the new flagship lens of our Sports line, the SIGMA 500mm F4 DG OS HSM fulfills
this need while incorporating SIGMA’s latest technologies and delivering a full range of advanced
features and functions: enhanced dust- and splash-proof construction, Optical Stabilizer (OS)
system, SIGMA Tele Converter compatibility, AF function switch, SIGMA’s latest-generation Hyper
Sonic Motor (HSM), and more. Combining top-level optical performance with functionality for
challenging shoots, SIGMA 500mm F4 DG OS HSM | Sports sets a new standard for
high-performance telephoto lenses.

[Key features]
1. Outstanding functionality for challenging shoots.
● Enhanced dust/splash-proof construction and available exclusive
Protector
Designed for top performance in tough shooting conditions, the SIGMA 500mm F4 DG HSM |
Sports features highly effective dust- and splash-proof construction. The front of the lens
features a water- and oil-repellent coating that allows water to be wiped away easily and helps
prevent oil from sticking to the surface. This feature is particularly useful when shooting in a
drizzle or near ocean spray. The lens is compatible with the exclusive SIGMA Protector LPT-11
(sold separately), which effectively helps prevent damage to the lens during shooting and maintenance.

Magnesium alloy barrel
To help minimize the weight associated with a hyper telephoto lens, the lens barrel is
made with a magnesium alloy. Both lightweight and tough, this alloy contributes to the
outstanding maneuverability of SIGMA 500mm F4 DG HSM | Sports.

Carbon fiber hood
The lens hood is made of carbon fiber, which is both lightweight and strong. In fact, the entire
lens is designed to be lightweight for outstanding performance in tough shooting conditions.

Tripod socket with 90° click stops
Since photographers often prefer to use a hyper-telephoto lens with a monopod or tripod, the
lens features a large and extremely stable tripod socket. Antistatic nickel plating on the socket parts help enhance the quality and durability of
the 90° click stops, which make it easy to switch between vertical and horizontal shooting positions.
The click position may be canceled by turning off the “de-clicking” switch.

The lens also comes equipped with a dedicated strap for the tripod socket, making it easy to carry equipment without undue stress on the camera mount.
* Tripod socket cannot be detached from the lens
*Strap included

Nikon electromagnetic diaphragm mechanism included
The lens for the Nikon camera includes the electromagnetic diaphragm mechanism and is
able to receive the appropriate signals from the camera body. This feature ensures precision
diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

2. Top-level optical performance
The lens incorporates two FLD and one SLD glass elements, while the optimized power distribution
helps minimize spherical aberration and axial chromatic aberration. The optical system also
effectively minimizes transverse chromatic aberration, which can affect the edges of the shots
taken in the telephoto range. In addition, image quality remains exceptional when the lens is used
with a SIGMA Tele Converter (sold separately).

Circular PL Filter RCP-11 is a drop-in polarized filter (sold separately).
Circular PL Filter RCP-11 is a drop-in filter that can easily be rotated while the lens is in use. (A
protector that is inserted in a slot at the rear of the lens comes with the lens as standard
equipment.)

3. Functions that satisfy the demands of professional photographers.
OS system with acceleration sensor and new Intelligent OS algorithm
The Optical Stabilizer (OS) system features an acceleration sensor to deliver even more precise performance and up to approximately four stops of stabilization. Two OS modes are available:
Mode 1 for general photography and Mode 2 for motor sports and other applications requiringpanning. In Mode 2, the acceleration sensor teams up with the Intelligent OS and its updated stabilization.

AF function switch with preset AF modes
The AF function switch allows you to set your own autofocus specification. The lens can remember
the focus position of your choice or turn off AF until it is needed.
Note: Image is for SIGMA mount lenses. Available switch functions may vary by mount.

Manual override incorporated to make two full-time manual modes switchable.

In addition to AF/MF, MO (Manual Override) is incorporated as one of the options of the focus mode
switch. By setting it to the MO position, it switches to manual focus by rotating the focus ring even
during continuous AF. With AF position, standard full-time manual focus is available. Using the
optional

SIGMA USB DOCK, it is possible to adjust the MO position’s sensitivity to switch to manual focus.

Quieter and Faster “Optimized AF”
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF. With the
further enhanced AF algorithm compared to previous models, continuous
AF (AF-C) improves the focusing efficiency.

4. SIGMA Tele Converters, mount converters, and USB DOCK make possible
customization and flexible adjustment for convenience or a specific purpose.

AF is effective even when Tele Converters are attached
Tele Converters that are newly designed to match the new lens line-ups
(optional) can be attached. The addition of SIGMA’s TELE CONVERTER
TC-1401 or TELE CONVERTER TC-2001 produces a AF 700mm F5.6
hyper-telephoto lens or a AF 1000mm F8 hyper-telephoto lens respectively.
* When shooting subjects with low contrast or luminosity value, focus may not be spot on the subject.

SIGMA USB DOCK – Customizable to your needs
Customization including firmware updates, focus adjustment, setting of full time
manual operations as well as adjustment of the timing to switch to MF when
rotating the focus ring is available with the optional SIGMA USB DOCK, by
connecting it with the dedicated software “SIGMA Optimization Pro” on a
computer. With this lens, custom mode that can be set depending on the photography situation is
available by switching it on the lens. Through custom mode, it is possible to set AF speed, focus
limiter where desired focus range can be adjusted, and OS where one of the patterns for optical
stabilizer can be selected from “Dynamic View Mode”, “Standard” and “Moderate View Mode”.

5. SIGMA GLOBAL VISION product lines are setting new benchmarks for image
quality

[Sports]
Sophisticated optical performance and expressiveness-
High action-capture performance, enabling photographers to get the exact
shots they want.
SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art, and
Sports. While offering sophisticated optical performance and expressiveness, our Sports line lenses
deliver high action-capture performance, enabling photographers to get the exact shots they want.
With these lenses, fast-moving subjects even at distance can be well captured. This
high-performance line also offers a variety of functions to aid the photographer in challenging
conditions and scenarios. Besides sports photography, these lenses are also perfect for nature
shots featuring birds and wildlife, as well as aero photography, trains, motor sports photography
and portraits. Another major feature of our Sports line lenses is their wide range of customization
options: using the dedicated software, all sorts of settings can be tailored to the personal
preferences of the photographer.
