10 Best Canon Zoom Lenses 2025 in the United States

The Canon RF100-300mm F2.8 L is a high-end telephoto zoom lens designed for mirrorless cameras, particularly appealing to professional photographers and videographers. It features a focal length range of 100-300mm, which offers great versatility for capturing distant subjects, whether you're shooting wildlife, sports, or landscapes. The fast f/2.8 maximum aperture throughout the zoom range allows excellent control over depth of field, enabling striking bokeh and improved performance in low-light conditions. This lens also excels in autofocus speed and accuracy, ensuring that your shots come out sharp even in dynamic situations.

Another major strength of this lens is its exceptional image quality. With one flourite lens and four ultra-low dispersion (UD) elements, it minimizes chromatic aberrations, while the Super Spectra Coating helps reduce ghosting and flare. Additionally, the built-in optical image stabilization provides up to 5.5 stops of shake correction, making it easier to shoot handheld.

However, there are some considerations to keep in mind. Weighing in at 5.7 pounds, this lens is relatively heavy, which may be cumbersome for extended use or for those who prefer a lighter setup. Its size can also make it less portable for casual shooting. While it is built to last with high-quality materials and weather sealing, these features may come at a premium price, making it less accessible for amateur photographers.

The Canon EOS R3 combined with the RF 70-200mm F2.8 L IS USM lens is a powerful setup for photographers needing a versatile telephoto zoom. The lens offers a useful focal length range up to 200mm with a bright, constant f/2.8 aperture that helps deliver sharp pictures even in low light, and it keeps background blur smooth for standout portraits or wildlife shots. Image stabilization is built in, reducing blur from hand shake, which is especially helpful when shooting at long zooms or slower shutter speeds. Autofocus is fast and accurate thanks to Canon’s Dual Nano USM system and contrast detection, making it easier to capture moving subjects clearly.

The camera sensor is a high-quality 24.1-megapixel full-frame CMOS, paired with a powerful processor that handles high ISO settings well for shooting in darker environments. On the downside, the body and lens are not weather sealed, so they may not hold up well in wet or dusty conditions without extra protection. While the camera-lens combo is described as compact and lightweight for its class, it’s still a professional-level tool and might feel bulky for casual use or travel.

This package is ideal for professional photographers or serious enthusiasts who want excellent image quality, reliable autofocus, and a bright zoom lens for sports, wildlife, or event photography. However, those in need of rugged weather resistance or ultra-portability might consider other options.

The Canon 300mm F2.8 L IS USM II lens is a high-quality telephoto lens designed primarily for sports, wildlife, and action photography where a fast aperture and steady images are essential. It has a fixed focal length of 300mm, which means no zoom capability, but this also helps deliver sharp, bright images thanks to its wide f/2.8 aperture. The aperture allows for great background blur and excellent performance in low light.

This lens features image stabilization that Canon claims can compensate for up to 4 stops of camera shake, making handheld shooting easier despite its weight. Speaking of weight, it’s quite heavy at around 5.3 pounds, so it might be less comfortable for long handheld sessions but is well-built with professional-grade materials and some weather sealing to protect against dust and moisture. Autofocus is fast and accurate, which is important when capturing moving subjects.

The lens is compatible with Canon EF mount cameras and has a reputation for excellent optical quality, though it does not zoom and is rather large and heavy compared to lighter zoom lenses. It is best suited for serious photographers who need top-notch image quality and speed in a fixed 300mm reach rather than casual users or those wanting more versatility in focal length.
