The EF 300mm f/2.8L IS II USM Lens from Canon is the perfect choice for nature, wildlife and sports photographers.
You might wonder why? Well, the smooth and fast focussing makes it amazing for shooting fast moving subjects. The large apertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur. allows for faster shutter speedSHUTTER SPEEDAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Shutter speed is the length of time that a single frame is exposed for, more specifically how fast the shutter opens and closes to permit light entering the lens, to reach the sensor. A slow shutter speed means a longer exposure time useful for motion blur like the silky look of flowing water, whereas a fast shutter speed means a shorter exposure time useful for freezing the appearance of motion in images like a hummingbird in flight. It is measured in seconds starting at 1 second and halving our doubling in time.
For example: 1/2s, 1/4s and 1/8s are all fractions of a second with 1/2s being the longest exposure time, 1/4s half of that and 1/8s another half etc.s, especially in low-light conditions. And the large aperture creates beautiful bokehBOKEHPronounced: /ˈboʊkɛ/, /ˈboʊkeɪ/ [boh-kay] or /ˈboʊkə/ [boh-kə]
Originating from the Japanese word Boke (ボケ), meaning 'blur' or 'haze', it refers to the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. It has also been defined as the way the lens renders out-of-focus points of light. Bokeh depends on various aspects of lens design. Aperture design has the largest effect on Bokeh, and generally a lens with a more rounded aperture produces a more pleasing, natural Bokeh.. (Who doesn't like that?)

Using the three mode Optical Image Stabilization allows you to shoot at shutter speeds 4 stops slower, and the advanced third IS mode activates only when the shutter button is fully pressed, so you can pan with fast-moving subjects without the IS function interfering with composition and framing. An ultrasonic autofocus motor (USM) enables smooth, fast and quiet autofocus and a Power Focus mode allows smooth focus change which is especially important while shooting video. A focus preset function allows you to store focusing positions and return to them in an instant when needed. An AF stop button will pause autofocus with just a touch and manual focus override allows precise manual focus even in AF mode.
Image sharpness is enhanced with fluorite optics that deliver reduced chromatic aberration and SWC (SubWavelength structure Coating) reduces flareFLAREOccurs when a point light source such as the sun or an artificial light (that is brighter than the rest of the scene), hits the front element of a lens resulting in a lack of contrast, haze, or unwanted semi-transparent objects being present in the image. You can avoid lens flare with a lenshood or filters, however, the effect is also useful for bringing artistic elements into an image, such as sun rays peaking out from behind a rock formation. and ghosting. A circular aperture design helps to produce pleasing out of focus areas.
Dust and water sealing keeps the lens functioning even in less than ideal conditions and magnesium and titanium construction elements make it lighter than its predecessor. Fluorine coating on the front and rear lens surfaces allows dirt to be removed easily and an attachment slot is provided for a wire-type security lock. The EF 300mm f/2.8L is compatible with Canon's EF1.4x III and EF2x III extenders and this lens includes a lens hood, 52mm drop-in gelatin filter holder, a detachable tripod collar and a hard travel case.
Fluorite optics for sharper images and less chromatic aberration.
Lighter weight due to magnesium and titanium construction elements.
Three IS (Image Stabilization) modes offer a 4-stop shutter speed advantage.
Advanced image stabilization Mode 3 activates only when shutter button is fully pressed, allowing for panning to follow fast-moving subjects.
Ultrasonic autofocus motor and inner focus system enable fast, smooth and silent AF action.
Power Focus mode allows smooth focus change when shooting video.
Focus preset allows you to establish focus points and return to them quickly when needed.
Focusing distance range can be selected with a switch on the lens barrel. By setting a suitable focusing distance range, actual autofocus time can be shortened. The three focusing ranges are 6.6-19.7', 19.7' to infinity and Full range.
An AF Stop Button allows you to immediately pause autofocus action with a touch of a button on the lens barrel.
Dust and water sealing for shooting in the most challenging environments.
Detachable lens hood, a detachable, rotatable tripod collar, drop-in gelatin filter holder and hard travel case are supplied with the 300mm f/2.8L lens.
