Overview
By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM,
this new lens achieves a compact size and a minimum focusing distance of 35cm. New material,
Thermally Stable Composite (TSC) maintains its structure and has little contractility especially in
varying temperatures, is incorporated into the lens barrel. It is convenient when you wish to keep
your equipment to a minimum and yet still be prepared for all opportunities and situations, such as
travels.
A wide range of photography is possible in one lens
Covering wide angle 18mm to telephoto 250mm, this versatile lens designed exclusively for digital SLR
cameras, is suitable for all-purpose photography including landscape, sport, and macro photography. It is
convenient when you wish to keep your equipment to a minimum and yet still be prepared for all
opportunities and situations, such as travels.
Excellent for macro photography
Close-up capability is improved with the minimum focusing distance of 35cm throughout the entire zoom
range, and maximum magnification ratio of 1:2.9. In APS-C size equivalent, macro photography with
approximately 1:2 magnification ratio is possible. In addition, with this lens, the size and framing of
subjects can be adjusted by rotating a zoom ring, making macro photography easier than using fixed focal
macro lens. For further convenience, the maximum magnification ratio at each focusing distance appears
on the side of the lens barrel.

Revolutionizing the design foundation results in compact size
Optimization of the power arrangement by such as incorporating double-sided aspherical lenses, and
reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately
13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 73.5mm x Length 88.6mm. It ensures portability and overall ease of use, making it perfect for travel and leisure
photography.
New material TSC (Thermally Stable Composite)
The new material “TSC (Thermally Stable Composite)”, which has little contractility especially in
temperature changes, as well as maintaining firmness, is incorporated into the lens barrel. Compared to
Polycarbonate which is generally used, TSC has higher elasticity by approximately 25%. Since thermal
shrinkage is low, it has high affinity to metal parts which contributes to high quality product
manufacturing. It also contributes to the parts such as the zoom ring and scaling to be slimmer.
Brass made bayonet mount
This lens incorporates brass made bayonet mount which has both high accuracy and solidity, same as
the mount for camera body. The special treatment to reinforce the strength is applied on the surface to
make it a high quality lens that is resistant for long-term use.
Optical Stabilizer (OS)
Sigma’s own unique Optical Stabilizer (OS) function is incorporated. It offers effective correction of
approximately 4 stops, which makes it possible to compensate camera shake even in macro range
photography where a small blur can be easily identified. When photographing a moving subject such as
motor sport, it automatically detects camera move, and offers effective correction for camera shake.
Superior optical performance
SLD (Special Low Dispersion) glass element offers excellent correction of color aberration. Three
aspherical lenses including double-sided aspherical lens together with the latest design, prevent and
correct all types of aberrations including astigmatism, achieving high quality images throughout the
entire zoom range.
Flare and ghosting conscious design blades
From an early stage, flare and ghosting are thoroughly measured to establish the design which is
resistant to strong incident light such as backlight. Super Multi-Layer Coating reduces flare and
ghosting, and provides sharp and high contrast images even in backlit conditions. Supplied petal-type
hood can be attached to block out extraneous light which has a harmful influence on rendering of the
lens, and prevent internal reflections to occur.
