Canon EF 300mm F4 L USM Review

Canon EF 300mm F4 L USM

General information

This is a prime lens manufactured by Canon and the lens was released 1991.
The lens belongs to the category telephoto prime lenses, a telephoto lens where you do not 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.

This lens can also be difficult to find in stores, as 'new'. 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 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.

Lens brightness and image stabilizer

The lens brightness and aperture value is f/4.

The lens is to considered fairly 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. Lenses with good aperture values and longer focal lengths, such as this lens, tend to be popular amongs sports and nature photographers.

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.

Extendable.

Tripod Mount

This lens is equipped with a tripod mount, which makes use of a tripod easier and more stable.
