Sigma 24-135mm F2.8-4.5 IF Review

General information

This is a zoom lens manufactured by Sigma and the lens was released 2003.
The lens belongs to the category standard 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 constructed to fit all models of Canon and Nikon cameras, regardless of camera model or type of sensor.

Here it is the only Canon version of the lens that has a built-in autofocus (AF) motor. The possibility to use autofocus (AF) is available for Nikon cameras but only if the camera itself has a built-in autofocus (AF) motor. Some cheaper and budget camera models from Nikon lacks a built-in autofocus motor, and we at Lensora appreciate autofocus, so in the list of compatible cameras we have chosen to display only the cameras that you can get autofocus with.

The lens has a focal length of 24-135 mm. Depending on which camera the lens is used, the experienced and perceived focal length will be different. Please visit the list of compatible cameras below, it will provide the equivalent focal length you get on each 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 24 mm the lens brightness is f/2,8 and at 135 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.

The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow 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.

Together with the lens there is a lens hood included but we have unfortunately no further information on model etc so feel free to contact us if you know more.

Things to consider before buying

Below you will find some summarized points and facts that can be considered as the 'pros and cons' of this lens.
