Introducing the Canon RF 200-800mm F6.3-9 IS USM, the world’s first full-frame zoom lens with a maximum reach of 800mm. This lens offers unparalleled image quality and versatility, making it a game-changer for wildlife and sports photography. What sets it apart is its compatibility with Canon’s teleconverters, allowing for a reach of up to 1600mm. However, it’s important to note that using the lens with a 2x teleconverter may compromise image quality.
Designed to work seamlessly with Canon’s flagship APS-C mirrorless camera, the Canon EOS R7, the RF 200-800mm is a winning combo for hobbyists and enthusiasts. Its effective reach extends to a remarkable 1200mm, thanks to the 1.5x crop of the sensor format. Not only will this lens appeal to EOS R7 users, but it will also find its place in the hands of EOS R8 and EOS R5 owners who have a passion for sports and wildlife photography.
During a short review period, I had the opportunity to pair the RF 200-800mm with the Canon EOS R5. The lens, weighing 72.3 oz / 2,050 g and measuring 12.36in / 314 mm in length, felt well-balanced when attached to the camera. Unlike traditional front-heavy Canon DSLR lenses, the RF 200-800mm’s weight distribution is more evenly placed towards the rear.
As you zoom in, the lens extends in length, which is why it is advisable to keep the lens hood attached to reduce lens flare. Despite its large size at 800mm, the lens remains manageable and easy to carry for extended periods. The controls, including the dedicated control ring, have a smooth and responsive feel. Although the lens is not part of Canon’s pro-grade L-series, its build quality is top-notch and weather-sealed, ensuring durability in various conditions.
One of the most impressive features of the RF 200-800mm is its image stabilization capabilities. Canon claims that it offers up to 5.5 stops of optical stabilization, which extends to 7.5 stops when paired with cameras equipped with sensor-based stabilization like the EOS R7 and EOS R5. The lens allows for sharp handheld shots even at slow shutter speeds as low as 1/30sec, although it is important to note that stationary subjects are necessary to avoid motion softness and blur.
In addition to its incredible reach, the lens also boasts a close focusing distance of 0.8m at 200mm, resulting in a generous magnification ratio. This characteristic allows for stunning close-up shots, as observed in the picture of tiny cold season berries taken at the lens’ minimum focusing distance.
However, the modest maximum aperture of f/6.3-9 is worth discussing. While it does not affect depth of field, it does impact the ability to freeze fast-moving action with an adequate shutter speed. To capture sharp details of birds in flight, a shutter speed of around 1/1000s is recommended. When combined with the f/9 aperture at the telephoto end, bright sunlight becomes a necessity to achieve the correct exposure. Using a 2x teleconverter with the RF 200-800mm is unrealistic, as it would result in a maximum aperture of f/18 at 1600mm. Nevertheless, considering the lens’ long reach, the teleconverter may not be necessary.
I tested the lens over the course of a bright afternoon with intermittent sun and clouds, allowing for optimal conditions. However, in low light, the f/9 aperture can be challenging, requiring higher ISO settings. Despite this compromise, the RF 200-800mm remains a relatively lightweight full-frame lens with an impressive zoom range and reach.
Image quality is remarkably sharp at the wide 200mm setting, although a slight loss in clarity is observed at 800mm, as expected from a lens with such an extensive zoom range. For photographers solely interested in the telephoto end, the RF 800mm f/11 IS STM may be a suitable alternative.
During my review, I also tested the lens’ ability to control flare and observed its bokeh quality. Shooting towards the light, scattered through a willow tree, revealed that the lens handles flare well. The bokeh, although exhibiting a pronounced cat’s eye effect in the corners, remains smooth overall, with minimal chromatic aberration or distortion.
Overall, the Canon RF 200-800mm F6.3-9 IS USM presents itself as a compelling choice, particularly when paired with the Canon EOS R7. It is suitable for safari photography, capturing grassroots sports, and capturing birdlife in fair weather. The lens is priced at £2,299.99, with sales starting in December 2023. US and Australia pricing will be updated soon.
In conclusion, the Canon RF 200-800mm F6.3-9 IS USM is a groundbreaking lens that offers exceptional image quality and versatility. Its extensive reach, combined with its lightweight design, makes it a valuable tool for wildlife and sports photographers. Despite its modest maximum aperture, it delivers impressive performance and image stabilization capabilities. With its release approaching, photographers will have the opportunity to capture stunning shots with this remarkable lens.
