Canon RF 28-70mm f/2L USM Zoom Lens

Set new standards in photography

Advanced L-series zoom featuring a very fast f/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. and delivering exceptional image quality. It redefines zoom lensZOOM LENSAllows a camera to, unlike a fixed-focal length or prime lens, change smoothly from a long shot to a close-up or vice versa by varying the focal length. A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Due to more moving parts, zoom lenses often produce images of slightly lesser quality than their prime lens counterparts. However due to the inherent flexibility of being able to vary the focal length, they are extremely popular for photography where composition needs to be adapted quickly - such as at weddings, for example. image quality. The RF 28-70mm f/2L USM offers the kind of image quality you’d expect from a 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. and adds an f/2 maximum aperture for more creative control.

A great lens for...

• Travel photography: Travel with a single zoom for space-saving flexibility. A versatile 28-70mm range is useful for many subjects, from big-sky landscapes to portraits, fine art and street photography.
• Wedding photography: Work quickly and quietly in a variety of situations. The RF 28-70mm f/2L USM features an f/2 maximum aperture, letting you control shallow depth of field in portraits and capture ambience in low light.
• Photojournalism: The zoom and 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. recompose and reframe quickly to capture that decisive moment. Focus and shoot in low light, and let Canon’s L-series quality inspire confidence – even in bad weather.

Image quality that has to be seen to be believed

The RF 28-70mm f/2L USM has all the optical, mechanical and electronic advantages of the EOS R system. Achieve extraordinary image quality and expect very high sharpness with low levels of distortion.

Smooth, near silent autofocusing

Focus quickly and in near silence, thanks to an advanced ring-type USM AF motor. When combined with the EOS R system’s silent shooting technology, photographers can remain discreet.

Simply brilliant in low light

Experience 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 and f/2 aperture that can freeze subject and camera movement. With a shallow depth of field, the RF 28-70mm f/2L USM is ideal for emphasising a pin-sharp subject.

Intuitive and seamless control

The RF 28-70mm f/2L USM features a customisable Lens Control Ring, which lets photographers respond instinctively to changing conditions by quickly adjusting a variety of settings including aperture, shutter speed, ISO ISO Exposure is controlled by three elements: Aperture, Shutter Speed and ISO. The ISO speed determines how sensitive a camera's sensor is to incoming light. A higher ISO speed absorbs more light, resulting in a brighter exposure, however, a higher ISO also results in more digital noise in low-light conditions. Cameras with larger sensors (like full-frame cameras) typically have higher ISO speed capability and produce less digital noise at high ISO settings. Digital cameras include a control for adjusting ISO speed, some of which can be set to adjust automatically in combination with certain other exposure settings. ISO is indicated in numbers usually starting at 100 and going upward (200, 400, 800, 1600 etc.) doubling in sensitivity each time. Most cameras also indicate 3rd stop intervals (100, 125, 180, 200 etc.)and exposureEXPOSUREExposure is controlled by three elements: Aperture, Shutter Speed and ISO. Achieving the correct exposure is similar to collecting rain in a bucket, up to an optimum level. The rate of rainfall is out of your control (light), yet you can control these three factors: the bucket’s width (lens aperture), the duration you leave it in the rain (shutter speed), and how effective your bucket is in collecting rain (ISO). These three elements work together to control the amount of light per unit area, preventing underexposure (too dark) or overexposure (too bright), giving you a natural looking image. compensation.
