Sigma 18-125mm f/3,8-5,6 DC OS HSM Review

General information

This is a zoom lens manufactured by Sigma and the model was launched 2008.
The lens belongs to the category  normal zoom lenses, a normal lens where you have the possibility to zoom in and out.

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 18-125 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 29-200 mm if you have a Canon camera or 27-188 mm if you have a Niko camera.

Lens brightness and image stabilizer

The lens brightness and aperture value is f/3,8-5,6.

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/3,8 and at 125 mm the brightness is f/5,6. 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".

Different versions of the lens

This lens has replaced an earlier version and this lens is currently the newest version but please compare it with the earlier versions before you buy it.
