This is a zoom lens manufactured by Sigma and the lens was released 2012.

Product description from Sigma
At launch 2012 Sigma wrote this regarding Sigma 18-200mm F3.5-6.3 II DC OS HSM:
Compatibility, autofocus 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 autofocus is available for all cameras.
The lens has a focal length of 18-200 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 29-320 mm if you have a Canon camera or 27-300 mm if you have a Niko camera.
A positive thing is that this lens has a versitale zoom range, where the difference between 'maximum zoomed out' to 'maximum zoomed in' increases the lens versatility since you as a photographer easily can compose your picture without moving yourself physically.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/3,5-6,3.
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/3,5 and at 200 mm the brightness is f/6,3. 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 62 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 "LH680-01".
