The addition of the 18-250mm F3.5-6.3 DC Macro OS HSM speaks to
Sigma’s versatile product lineup with this multipurpose zoom lens that
offers Optical Stabilization (OS)* and covers wide angle to telephoto to
macro photography. It differs from Sigma’s current 18-250mm F3.5-6.3 DC
OS HSM lens with its even more compact size, its macro capability with a
maximum magnification ratio of 1:2.9 and the use of Thermally Stable
Composite (TSC) material currently used only by Sigma.



TSC, which is incorporated into the lens barrel and is often compared to
polycarbonate, has a high degree of elasticity and exhibits little
variation in its structure in extreme temperature conditions. This means
that internal barrel expansion and contraction due to extreme
temperature variations is less prevalent. TSC also contributes to the
lens’ size reduction. The non-macro 18-250mm F3.5-6.3 without TSC weighs
22.2 ounces and is 3.1 by 4 inches in diameter, whereas the new macro
lens is 16.6 ounces and 2.9 by 3.5 inches in diameter.


Sigma optimized this lens’ power arrangement by incorporating
double-sided aspherical lenses and reexamining the design to achieve a
more compact filter diameter. The lens has an approximate 13x high zoom
ratio with a filter size of 62mm in diameter. Sigma’s unique OS system,
as well as one Special Low Dispersion (SLD) glass and three aspherical
lens glasses, compensate for camera shake and enable correction of color
aberration, respectively.



The new 18-250mm F3.5-6.3 DC Macro OS HSM lens is also equipped with
Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic
Motor (HSM) to ensure fast and quiet auto-focusing, and a rounded,
seven-blade diaphragm to create an attractive round blur to the out of
focus areas. The lens features a brass-made bayonet mount applied on the
surface to reinforce strength for long-term use and enable high
accuracy and solidity.
