Canon RF 24-105mm f/4L IS USM Zoom Lens

Your "take everywhere" 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.

The 24-105mm zoom covers wide-angle, standard and 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. 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. s.

The Canon RF 24-105mm f/4L IS USM Zoom Lens is a offers EOS R users a small, lightweight and compact general-purpose lens with 5-stops of image stabilisation and high optical quality and content 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.. 

• Portrait photography: The RF 24-105mm f/4L IS USM is great for sharp, shake-free portraits thanks to a 5-stop Image Stabiliser. Change focal length quickly without changing 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., thanks to a constant f/4 maximum aperture.
• Travel photography: A versatile and high-quality travelling companion, its tough L-series build quality protects against dust and moisture and is light enough to go places without weighing you down.
• Everyday creativity: The RF 24-105mm f/4L IS USM is a popular choice and perfect for bloggers, hobbyists and photo enthusiasts. A Lens Control Ring provides a tactile and intuitive way to adjust camera settings.

A supremely flexible and agile lens

The Canon RF 24-105mm f/4L IS USM makes it easy to get creative and achieve exceptional results. From indoor portraits to events outside, a 24-105mm zoom range lets you achieve more without changing lenses. An f/4 maximum aperture is consistent at all zoom settings.

Clearly a great performer

Aspherical and UD lens elements ensure excellent sharpness, which is preserved even when shooting handheld in low light, thanks to a 5-stop Image Stabiliser. Aspherical lens elements help to compensate for distortion and spherical aberrations plus allow a compact design.

Stay sharp!

Focus accurately and in virtual silence using Nano USM autofocus. Photographers will appreciate the speed with which critical sharpness is found, while filmmakers will love the smooth, steady focus transitions that this cutting-edge technology enables.

Any time, any place, anywhere

As an L-Series lens, the RF 24-105mm f/4L IS USM features the kind of robust, weather-sealed construction that inspires confidence. Fluorine coatings on the front and rear lens elements makes them easy to clean. This is truly a practical lens meant for travel.
