Sigma AF 18-50mm f/3.5-5.6 DC Zoom Lens for Four Thirds

Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.

Exclusively designed to suit the characteristics of digital SLR cameras featuring APS-C size image sensor. The image circle was designed to match the size of the image sensors of most digital SLR cameras and this has resulted in a compact lightweight lens. The use of aspherical lenses provides correction for various aberrations and makes high quality images a reality throughout the entire zoom range. Corresponding AF Mounts: SIGMA SA mount, NIKON mount, CANON mount, PENTAX mount.

The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance.

Exclusively designed to suit the characteristics of digital SLR cameras.

We took digital characteristics into consideration when designing the lens power layout and created the most suitable lens that makes high quality images a reality throughout the entire zoom range. We used the most appropriate coating for digital products to cut down flare and ghost caused by digital SLR cameras and to produce the best color balance. It can be used with the supplied lens hood to block out extraneous light.

A little about Wide Angle Lenses?

Wide angle lenses are ideal for capturing large subject areas whether it is landscapes, nature, outdoor scenes, or large groups. Any lens with a focal length much smaller than 50mm is considered a wide angle lens. Its design also allows for larger views in tight spaces. That makes it great for not cutting off important subject matter when increasing the distance between yourself and the subject is impossible.

Another benefit of wide angle lenses is that they are great for accentuating the foreground keeping it super sharp. At the same time, wide angle lenses make the background seem much further away. A prominent foreground set against a receding background often results in a very pleasing effect. Compared to a standard lens, wide angles have a better depth of field and clarity. 24mm and 28mm are the most common focal lengths.
