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 17-50 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 27-80 mm if you have a Canon camera or 26-75 mm if you have a Niko 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 17 mm or at 50 mm the aperture value can be f/2,8.

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 77 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 "LH825-03 583".
