The Sigma 18-35mm F1.8 DC HSM Art Lens offers an appealing combination: fast constant maximum aperture, quality optics and lightweight design. In fact, it is the very first 18-35 zoom lens with such a large F1.8 maximum aperture.

This quality Sigma zoom lens will successfully address the needs of professionals and amateur enthusiasts alike. Use it for landscapes, group portraits, kids' candids and much more. It's possible to focus on subjects as close as 11 inches away. You'll find that this is also an excellent lens for video imaging. Sigma uses a "Hyper Sonic Motor" (HSM) to drive the focusing mechanism. This motor is particularly smooth, fast and quiet.

What's Included With the Sigma 18-35 Lens?

This fast f1.8 lens comes complete with front and rear lens caps and a lens hood. It accepts 72mm filters. Is versatile lens is compatible with most major mounts:

  • Nikon F
  • Canon EF
  • Sony Alpha
  • Pentax K
  • Sigma SA

Advantages of an F1.8 "Fast" Lens

Lenses with relatively large maximum apertures often feature larger lens elements, and this Sigma lens is no exception. However, the advantages are substantial in certain critical shooting situations:

  • Low light
  • Fast action
  • Blurred background
  • Ease of composition

The wider the aperture, the less depth of field. Therefore, a photographer can select the wide-open f1.8 aperture combined with a faster shutter speed to blur the background and retain subject sharpness. The diaphragm is composed of nine rounded blades that add further to the blurred background effect.

Because a lens with a larger maximum aperture transmits more light, a photographer enjoys an important advantage in low-light and other challenging situations. More light coming through the lens means that it is easier to see what your composition will look like.

When you invest in a hi-quality zoom lens, you want to have confidence that edge-to-edge sharpness remains even when the lens is used at the maximum F1.8 aperture. The quality optics employed in the lens offer a level of edge-to-edge sharpness that should meet the demanding standards of exacting photographers.

Bundle and Save

The cost of the Sigma 18-35 f1.8 lens is mitigated to a degree by the fact that it Is much like having two or three prime lenses rolled into one. With an APS-C camera, you'll meet many of your normal lens and modest wide-angle needs. With a full-frame camera, the 18 mm focal length gives you some serious wide-angle capability. At the same time, the lens fully zoomed addresses everyday wide-angle composition possibilities.

Another great way to reduce the effective cost of the lens is through "bundling." Many suppliers will add numerous items to your purchase at little or no added cost. Monopods, backpacks and filters are great additions anyhow.

A Complete Lens Kit

A great way to add value to your purchase is to consider bundling the lens with any or all of the following:

  • Camera backpack
  • Monopod
  • Wireless remote control
  • 72 mm filters
  • Lens cleaning kit

Always make sure that all components of any given bundle are compatible with your camera.
