When it comes to its overall performance, the Canon RF 800mm F11 IS STM lens is simply outstanding. Even at the greatest focal length, it maintains an exceptional level of picture clarity and sharpness because to its cutting-edge optics and unique coatings.

A Super Spectra coating has been applied to the lens, which helps to reduce ghosting and flare. As a consequence, the images produced by the camera have a high contrast ratio and accurate color reproduction. In addition to that, the lens has a diffractive optic (DO) element built into it, which helps to drastically cut down on chromatic aberration, which in turn further improves image quality.

Autofocus System

Because it is quick, precise, and dependable, the autofocus technology of the Canon RF 800mm F11 IS STM lens enables photographers to track and record subjects that are moving. The lens is equipped with Canon’s STM (Stepping Motor) technology, which makes for a smooth and silent focusing performance.

This makes it an excellent choice for filmmaking in addition to photography. Because the autofocus mechanism is able to rapidly acquire focus even in difficult lighting circumstances, it guarantees that you will never miss an important moment in action.

Vibration Reduction

Even while shooting handheld, the RF 800mm F11 IS STM lens from Canon is equipped with effective Image Stabilization (IS) technology, which helps to reduce blur caused by camera shake and produces clear images regardless of the orientation of the camera. This is especially helpful when working with such a long focal length because even the slightest movement can be exaggerated when working with such a focus length.

Because the IS system can correct for camera vibration by up to four stops, photographers are able to take pictures at slower shutter speeds without compromising the quality of the images they capture. The built-in stabilization of the lens assures that you will be able to take photographs that are clear and devoid of blur, regardless of whether you are photographing moving animals or sporting activities.

Build Quality

While still retaining a lightweight and compact construction, the Canon RF 800mm F11 IS STM lens is constructed to be able to resist the rigors of operation in a professional setting. The lens has a mount made of metal and a sturdy exterior shell, giving it a structure that is both long-lasting and of excellent quality.

In spite of having an extraordinary focal length, the lens maintains a surprisingly low weight, which makes it easier to transport and work with for more extended periods of time during photography sessions. When working in harsh situations, having a lens that is dust- and water-resistant is a significant asset. This lens is equipped with dust- and water-resistant seals.

Handling and Ergonomics

When it came time to develop the RF 800mm F11 IS STM lens, Canon made sure to take into account how important it is to have a lens that is easy to handle and has good ergonomics. The manual focus ring on the lens is silky smooth, and sensitive, and the dedicated control ring can be programmed to modify a variety of camera settings to provide a smooth shooting experience.

Both rings are located on the lens’s manual focus ring. Additionally, the lens has a tripod collar that allows for a simple connection to tripod heads and ensures the lens’s stability when shooting at longer focal lengths. This feature is included as standard equipment.

Image Stabilization

When shooting handheld with a lens that has such a long focal length, the built-in Image Stabilization (IS) technology that is included in the Canon RF 800mm F11 IS STM lens is a game-changer. As a result of the IS system’s ability to efficiently adjust for camera shaking, photographers are able to get clear shots even when they are not using a tripod.

When shooting in difficult conditions or when mobility is of the utmost importance, this capability is very helpful. The image stabilization performance may be improved thanks to the integration of the lens’s stabilization technology with Canon’s EOS R cameras, which provides a smooth experience and excellent performance.

Shooting Experience

To say that using the Canon RF 800mm F11 IS STM lens for photography is a great experience would be an understatement. Because of its lightweight construction and careful attention to balance, the lens is easy to hold for long periods of time and is also quite pleasant to wear. The streamlined and effective autofocus technology guarantees rapid and accurate subject tracking, making it simple for photographers to seize important moments when they present themselves.

While shooting in calm locations, such as while photographing animals, the lens’s silent autofocus function is a really useful feature to have. In addition, the lens’s compatibility with Canon’s RF teleconverters enhances its versatility, making it possible to achieve an even wider focal length without sacrificing picture quality.

Image Quality

The exceptional image quality that can be achieved with the Canon RF 800mm F11 IS STM lens is made possible by its cutting-edge optical design. The specialized elements and coatings of the lens collaborate to reduce the appearance of aberrations, so improving the image’s sharpness and contrast. The Super Spectra coating successfully eliminates ghosting and flare, which results in photographs that have rich coloration and superior contrast.

The diffractive optic (DO) element plays a significant role in lowering chromatic aberration, which helps to ensure that colors are reproduced accurately and that pictures have a high resolution. Photographers can depend on this lens to produce photographs that stand out with remarkable clarity and to capture amazing details with ease.

Teleconverter Compatibility

The Canon RF 800mm F11 IS STM lens is compatible with Canon’s RF teleconverters, making it an attractive option for photographers who want to increase the scope of their shots even more. The effective focal length of the lens may be expanded by connecting a teleconverter, such as the Canon RF 1.4x or RF 2x. This enables photographers to get substantially closer to the subjects of their photographs without severely degrading the quality of the images they capture.

This adaptability is especially beneficial when it comes to photographing wildlife and sports, two types of photography in which being able to reach objects that are at a greater distance may make a huge difference. Even when using teleconverters, the lens continues to deliver outstanding optical performance. This enables photographers to obtain amazing image quality even when working with extremely long focal lengths.

Comparison with Competitors

When compared to other lenses in its class, the Canon RF 800mm F11 IS STM lens has a combination of features that is unmatched in the industry: great performance, lightweight construction, and an affordable price. Although competing super-telephoto lenses on the market may offer larger maximum apertures or higher levels of weather sealing, the RF 800mm F11 IS STM lens distinguishes out from the competition due to its compact size and reasonable price point.

Because of its lightweight design, the lens is more portable and simpler to use, which is particularly helpful while working in demanding conditions or during extended shooting sessions. In addition, the remarkable picture quality of the lens, along with its dependable focusing technology, makes it possible for photographers to take consistently stunning photographs, regardless of the conditions under which they are shooting.
