This is a zoom lens manufactured by Sigma and the model was launched 2006.
The lens belongs to the category
normal zoom lenses, a normal lens where you have the possibility to zoom in and out.
|
|
The lens has macro-properties but is unable to reproduce things in their real size (otherwise called '1:1'). You should therefor consider taking the term 'macro' with a pinch of salt and if the macro-possibilities you are looking for you should perhaps look at other options.

| Compability, auto focus and focal length |
| This lens is designed and meant for 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 27-75 mm on your Nikon camera.

| Lens brightness and image stabilizer |
|
The lens brightness and aperture value is f/2,8.
|
|
This aperture value indicates that the lens is very bright.
This will make it so much easier shooting in darker environments where you do not want or can use flash lighting, for example in churches or at different sports venues.
|
| A feature worth commenting, which is also related to lens brightness, is that the brightness and maximum aperture-value remains constant regardless of focal length used. This makes it easier for you as a photographer. No matter if you are have the focus ring and focal length at 18 mm or at 50 mm the aperture value can be f/2,8. |
| The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds. Since the lens is bright, with good aperture value, the lack of image stabilization might not be that big of a deal, although a image stabilizer is always an advantage to have.

| Filter and Lens Hood |
| The lens has a traditional filter thread on the front and its measuring 72 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.
|
|
