The ultimate 50mm lens
The RF 50mm f/1.2L USM prime lensPRIME LENSA photographic lens used as an (1) alternative, fixed focal length alternative to a zoom lens or, (2) more traditionally, as the primary lens in a combination lens system. In the first sense, a prime lens is known for having a larger maximum aperture and consequently offers greater shutter speeds, having advanced optics and weighing less than zoom lenses, albeit less flexible, because of their simpler construction with less moving parts. In the second sense, a prime lens refers to the primary lens when paired with other optical devices. A prime lens's focal length is fixed and the photographer is required to move closer or further to achieve the correct image composition. for Canon EOS R users sets new standards in photographic performance, delivering supreme sharpness, extra creative control and a low-light performance that’s simply remarkable. Outstanding clarity and sharpness mean you’ll see noticeably more detail, even right at the edges of the frame.

Portrait photography: The lens’s 50mm focal lengthFOCAL LENGTHMeasured in mm, it is the distance from the focal point of a lens (its centre or curved mirror where light converges) to the plane of the image sensor (film) when an object is in focus. A shorter focal length lens sees a wider image and a longer focal length brings your subject closer. For example, a 15mm lens sees a very wide image and is perfect for landscape photography. Conversely, a 500mm lens sees a very narrow image, brings the subject much closer and is thus great for subjects that are far away, like a bird in a tree. With zoom lenses, its minimum and maximum focal lengths are indicated, for example, as 24-105mm. A zoom lens allows you to change the lens’ focal length, with shorter (wide-angle) and longer (telephoto) options, whereas a fixed focal length lens requires you to move back and forth to find the correct image composition. has a similar perspective to that of the human eye, and a super-wide f/1.2 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. that allows for extremely shallow depth of field – ideal for emphasising pin-sharp features like eyes against a soft, out-of-focus background.
Street photography: With its fast-maximum aperture and ability to focus exceptionally quickly, the RF 50mm f/1.2L USM is the perfect street photography lens, offering new levels of definition when shooting in available light.
Fine art: Printing a photograph that’s been captured with a lens like the RF 50mm f/1.2L USM is pure joy. Levels of detail are incredible, enabling fine-art photographers to produce ever-more impressive works for the exhibition.
The widest of wide apertures
The f/1.2 maximum aperture of the RF 50mm f/1.2L USM is the widest available in the Canon EOS line-up. It gives both photographers and filmmakers the ability to shoot with an extremely shallow depth of field – a great way to emphasise a subject against a complicated background.
Super sensitive in low light
The ability to work with such wide apertures lets photographers use fast 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 in low-light conditions, which can freeze both subject movement and camera shake. The RF 50mm f/1.2L USM is a great tool for capturing the atmosphere of any moment using only available light.
A ring-type USM autofocus system, more usually found in Canon’s super telephotoTELEPHOTOA lens with long focal length capable of making distant objects appear nearer thus larger. Essentially, it isolates and magnifies the subject so that it appears as a full image when shooting from a distance. Telephoto lenses are ideal for photographing subjects that are further away, such as wildlife and sports photography. lenses, moves the large glass elements found in the RF 50mm f/1.2L USM with ease. Sharp focus is found swiftly and accurately, and objects can be tracked and followed as they move around the frame.
