Compability, auto focus and focal length
The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens.
This lens is designed and meant for Canon and Nikon cameras with a smaller sensor (often referred to as 'APS-C') which means that the lens does not fit all camera models. By clicking on the link below you can make sure that the lens works with your camera model and you should do an additional check with your local dealer as well, before you buy the lens just to be sure.
The ability to use auto focus is available for all cameras.
The lens has a focal length of 18-50 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 29-80 mm if you have a Canon camera or 27-75 mm if you have a Niko camera.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/2,8-4,5.
This lens is not considered to have a good aperture value and brightness. It is something to consider before you purchase the lens. To compensate for this you might, while photographing in less favorable light conditions, be forced to either use higher ISO settings (which generates more noise in the image), slower shutter speeds (which may give some motion blur) or flash lightning. Read more at the link below what lens brightness means to you as a photographer.
One thing to consider is that the lens has a variable brightness, which means that depending on how much you are zooming the lens will have a different maximum aperture value. At 18 mm the lens brightness is f/2,8 and at 50 mm the brightness is f/4,5. Through the link below you can read more about what this could mean for you as a photographer.
Inside the lens there is an image stabilizer, which helps to fend off possible movements and tremors. This is very positive and can be of great help in situations and conditions where the light is inadequate and not enough for decent shutter speeds.

Filter and Lens Hood
The lens has a traditional filter thread on the front and its measuring 67 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.
If you buy this lens it will come with a lens hood, whose model name is "LH730-02 580".

Text from Sigma:"For use with smaller chip APS-c cameras only

Offers Sigma’s OS System (Optical Stabilization) allowing handheld photography even in low-light situations

HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus

Internal focus & zooming systems

Compact and lightweight at only 14 ounces

A lens hood and front & rear lens caps are included with the lens.

With the widespread popularity of the small sensor APS-c format cameras, the standard “kit” lens is often supplied at a very attractive price. Unfortunately, some of those kit lenses may be lacking in features and in image quality. In order to offer photographers an alternative to the camera manufacturers’ lenses, we have introduced our own “standard zoom” lens. Sigma’s 18-50mm F2.8-4.5 DC OS HSM with an almost 3 to 1 zoom range, this compact lens is great for vacations scenic, quick snap shots of the kids playing in the backyard, a day at the beach or even casual portraits. Three Aspherical glass elements offer correction for distortion, two SLD (Special Low Dispersion) glass elements provide optimum color correction and sharpness And Super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. It employs Sigma’s state of the art technology to assure top quality images at a value price. "
