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.

- Wireless remote control
- 72 mm filters
