Canon EF 300mm f/4L IS USM Lens Review

The Canon EF 300mm f/4L IS USM is a relatively inexpensive professional grade telephoto prime lens designed for Canon full frame digital SLR cameras. It can also be used on Canon APS-C bodies and will provide an equivalent field of view to a 450mm lens on a full frame body.

The lens features a relatively fast f/4 maximum aperture for work in lower light than the consumer 70-300mm zoom lenses that are a full stop slower at 300mm than the Canon EF 300mm f/4L IS USM.

I have not formally tested this lens yet, but plan to in the future. Generally the lens is favorably reviewed by photographers who own and use it.
