L'obiettivo EF 300mm è un teleobiettivo fisso prodotto da Canon Inc.. L'obiettivo ha un attacco EF ed è quindi compatibile con macchine fotografiche reflex della serie EOS. Questo obiettivo è usato principalmente nella fotografia sportiva e naturalistica, ma la sua lunghezza focale è corta abbastanza da permettere anche di effettuare ritratti stretti in primo piano. Grazie alla sua capacità d'ingrandimento alquanto elevata, può essere impiegato anche in alcuni tipi di macrofotografia.

De EF 300mm is een familie van teleobjectieven gemaakt door de Japanse fabrikant Canon. Alle modellen zijn voorzien van een EF-lensvatting en daarmee geschikt voor de EOS-cameralijn van dezelfde fabrikant. In totaal zijn er vijf varianten verschenen van dit objectief, allen voorzien van het (semi-)professionele L-label.

佳能 EF 300mm 鏡頭是一系列由佳能公司生產的定焦鏡頭，一共有下列幾種型號：
* EF 300mm f/2.8 USM
* EF 300mm f/2.8 IS USM
* EF 300mm f/2.8 IS II USM
* EF 300mm f/4 USM
* EF 300mm f/4 IS USM 當300mm鏡頭用於佳能數碼EOS系列的APS-C幅面機身（如佳能 EOS 550D）時，視角會變窄，其等效於全幅機身上的480mm視角（乘以系數1.6）。當用於APS-H幅面機身（如佳能 EOS-1D Mark IV）時，其等效於全幅機身的390mm視角（乘以系數1.3）。

The EF 300mm lens refers to a family of telephoto prime lenses made by Canon, five of which have been sold to the general public and one of which was only made on special order. The lenses have an EF type mount which fits the Canon EOS line of cameras. This lens is most commonly used by sports and wildlife photographers, but is short enough to be use for extreme close-up portraits. Because of its rather high native magnification, it can be used for some macro type photography.

The EF 300mm lens refers to a family of telephoto prime lenses made by Canon, five of which have been sold to the general public and one of which was only made on special order. The lenses have an EF type mount which fits the Canon EOS line of cameras. When used on a digital EOS body with a field of view compensation factor of 1.3x, such as the Canon EOS-1D Mark IV, it provides a narrow field of view, equivalent to a 390 mm lens mounted on a 35mm frame body. With a 1.6x body such as the Canon EOS 650D, it provides a narrower field of view, equivalent to a 480 mm lens mounted on a 35mm frame body. This lens is most commonly used by sports and wildlife photographers, but is short enough to be use for extreme close-up portraits. Because of its rather high native magnification, it can be used for some macro type photography.
