10 Best Canon Telephoto Lens 2025 in the United States

The Canon EOS R6 Mark II KIT is designed for serious photographers and videographers, offering professional-grade features. The kit includes two high-quality lenses: the RF24-105mm F4 L IS USM and the RF 70-200mm F2.8 L IS USM telephoto zoom lens. These lenses cover a wide focal range, making the kit versatile for various photography needs from wide-angle to telephoto shots.

The bright f/2.8 aperture of the telephoto zoom lens is excellent for low-light conditions and provides beautiful background blur (bokeh). The image quality is top-notch, thanks to the 24.2 megapixel full-frame CMOS sensor and DIGIC X image processor, which ensures sharp, detailed images even in challenging lighting conditions. Optical image stabilization helps in reducing camera shake, particularly beneficial for handheld shooting and videography. Autofocus is fast and accurate, using contrast detection technology, making it reliable for capturing moving subjects.

The build quality is robust with weather sealing, ensuring durability and performance in various environmental conditions. The camera's compact and lightweight design makes it portable and easy to handle, despite having professional-grade features. However, the camera flash is built-in, which may not be sufficient for all lighting needs, and additional external flash units might be required for professional use. The maximum video resolution is 1080p, which may not meet the demands of users looking for 4K video capabilities. Additionally, while the camera supports various file formats and has multiple connectivity options, it only includes one USB port, potentially limiting simultaneous connections for accessories. This Canon kit is highly suitable for professional photographers and videographers who need a versatile, high-performance camera system for a range of shooting conditions.

The Canon RF800mm F5.6 L IS USM telephoto lens is designed for those who need powerful zoom capabilities, making it an excellent choice for wildlife and sports photographers. With an impressive 800mm focal length, it allows you to capture distant subjects with stunning detail. The fixed aperture of F5.6 ensures consistent, high-quality images even in lower light conditions. One of its standout features is the optical image stabilization, which provides up to 4.5 stops of shake correction, ensuring sharp images even without a tripod. Additionally, it offers three IS operation modes to suit different shooting scenarios.

Autofocus speed and accuracy are top-notch, thanks to Canon's USM technology, making it easy to track and capture fast-moving subjects. The lens also boasts superior build quality with weather sealing, allowing you to use it in various outdoor conditions without worry. Despite its robust construction, it is relatively light at 6.9 lbs, though still somewhat heavy for handheld use over extended periods. The minimum focus distance of 8.53 ft. is quite reasonable for such a long lens, making it versatile for different shooting situations.

Its compatibility with the Canon RF mount system ensures seamless integration with EOS R series cameras. However, its size and weight may be a drawback for some, as it measures 6.4 x 6.4 x 17 inches and weighs 16 pounds, making it less portable. Additionally, it comes with a premium price tag, which might be a consideration for budget-conscious buyers. In conclusion, the Canon RF800mm F5.6 L IS USM lens offers exceptional image quality and performance for those serious about their telephoto photography, especially in challenging conditions.

Autofocus speed and accuracy are commendable, thanks to the USM motor, making it highly suitable for fast-moving subjects like wildlife and sports photography.

The build quality is robust, with weather sealing to protect against dust and water, allowing for reliable use in harsh conditions. Additionally, super spectra and air sphere coatings minimize ghosting and flare, maintaining high image quality in various lighting environments. The lens is relatively lighter than its predecessors, improving portability during extended shooting sessions. However, it does remain quite heavy and bulky compared to smaller lenses, which might be a drawback for some users.

Compatibility is excellent with Canon EF mount cameras, ensuring seamless integration into existing setups. This lens is best suited for professional photographers or serious enthusiasts who require top-notch performance and durability in a telephoto lens.
