Sigma 18-250mm f/3.5-6.3 DC OS MACRO Lens Announced

Sigma 18-250mm f:3.5-6.3 DC OS MACRO Lens

The Sigma 18-250mm f/3.5-6.3 DC OS MACRO lens was unveiled today as an all-purpose APS-C lens.  No pricing yet, but it should be available in July.

The new lens differs from the non-macro version in magnification ratio, but it also contains new material called Thermally Stable Composite (TSC). TSC is incorporated into the lens barrel and is often compared to polycarbonate. It 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. As a result, this is a more compact, multi-purpose lens for APS-C sized sensor cameras.
