General information

This is a zoom lens manufactured by Canon and the model was launched 1990.
The lens belongs to the category  telephoto zoom lenses, a telephoto lens where you have the possibility to zoom in and out.

It's been a long time since the lens and this model first was launched. Before you buy an older (and perhaps used and pre owned) lens a recommendation is to check with the manufacturer and their service centers whether there still are spare parts available. Hopefully spare parts wont be an issue but imagine accidently damaging the lens and finding out afterwards that no spare parts exists. We therefore recommend that you, to be sure, check this prior to purchasing.

If you buy a new lens, in a store, you always have your warranty to fall back on, regardless of the age of the lens but if you are interested in buying a pre owned and used lens without warranty this may be even more important to look up because you might otherwise be left without both warranty and spare parts.

Compatibility, autofocus and focal length

This lens is constructed to fit all models of Canon cameras, regardless of camera model or type of sensor.

The ability to use autofocus is available for all cameras.

The lens has a focal length of 100-300 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.

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/4,5-5,6.

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 100 mm the lens brightness is f/4,5 and at 300 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.

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 58 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.

There is a lens hood that fits the lens (model name "ET-65 III") but unfortunately this is something that is not included when purchasing the lens and must be ordered and bought separately, as an accessory.
