The EF 300mm f2.8L IS USM is my favorite travel lens for birds photography. It is lighter compared to the predecessor due to the main components are made of a magnesium alloy, which reduces the weight of the lens. This lens is generally used in wildlife / sports photography due to the large aperture. AF speed is extremely fast.
The EF 300mm f2.8L IS USM replaced the EF 300mm f2.8L USM, which was released in September 1987. It took Canon 12 years to replace the previous model. This shows that long telephoto lenses hold up the values quite well against time.
Large-aperture telephoto L lens with a camera shake correction function, which is best suited to shooting by holding the camera with hands Developed as a successor to the EF300mm f2.8L USM. A fluorite lens and two UD lenses are used in the optical system to assure very high picture quality. This lens has also a protection glass and a rear filter as standard, which are included in the number of lenses. The camera shake correction has an effect of approx. two stops in terms of shutter speed. This lens has also "camera shake correction mode 2" which corrects shaking of the viewfinder image when, for example, shooting a moving object, and a tripod can be used with the camera shake correction function ON. High-speed autofocusing is achieved by the weight reduction of the group of focusing lenses and improvement of the autofocusing drive algorithm. A new AF stop function, which stops autofocusing temporarily, is adopted. Manual focusing is performed mechanically to save power. Main components are made of a magnesium alloy to reduce the weight of the lens, including the optical system, making it much lighter than conventional lenses. Rubber parts are used as mount and switch components to achieve excellent dust- and drip-proofness. The tripod mount can be removed, and the drop-in filter 52 (standard), carbon fiber hood, and suitcase-type lens case are designed to be easy to use.
Specifications :
In the market, there are a few variations of EF 300mm. I have listed down all the models for your reference.
Enought of talking, let look at some sample images taken by this lens. The IQ of this lens is excellent even with a EF 2x TC II.
