10 Best Telephoto Lens For Canon Eos Rebel T7 2025 in the United States

The Canon RF100-500mm F4.5-7.1 L IS USM lens is a versatile super-telephoto zoom lens that offers a wide focal range from 100mm to 500mm, making it ideal for capturing distant subjects like wildlife or sports events using Canon EOS R series cameras. Its optical image stabilization provides up to 5 stops of shake correction, which is beneficial for handheld shooting, ensuring sharper images even in low-light conditions.

A significant strength of this lens is its autofocus system, which is high-speed, smooth, and quiet due to the Dual Nano USM technology, ensuring that you can quickly and accurately focus on your subject. This feature is particularly useful in dynamic situations where subjects may be moving rapidly.

However, the lens has a variable aperture of f/4.5-7.1, which means that while it can perform well in good lighting conditions, it may not be the best choice for low-light situations as it doesn't allow as much light in at longer focal lengths. Additionally, this lens is designed for the Canon RF mount, which isn't directly compatible with the EOS Rebel T-7's EF mount, necessitating an adapter for use.

In terms of build quality, the lens is part of Canon's L-series, known for robust construction and weather sealing, which can endure challenging environmental conditions. It's relatively lightweight for its class at 3 pounds, making it a more portable option for those needing long-reaching zoom capabilities without the bulk.

If you're using a Canon EOS Rebel T-7, this lens would require an adapter due to the different mounting systems, which might add to the overall weight and affect handling. For users with Canon RF mount cameras, this lens delivers excellent performance for a variety of long-range shooting needs.

The Sigma 150-600mm 5-6.3 Contemporary DG OS HSM Lens for Canon is designed for those who need a versatile telephoto lens. It offers a broad focal length range from 150mm to 600mm, making it suitable for wildlife and sports photography. The aperture range of f/5-6.3 is decent, though it might struggle in low-light conditions. Image stabilization (OS) is a significant plus, helping to reduce camera shake and produce clearer images, especially at longer focal lengths.

Autofocus speed and accuracy are generally reliable, thanks to the Hyper Sonic Motor (HSM), though it may not be the fastest in the market. The build quality is commendable; it features a water and oil repellent coating on the front glass, which aids in easy maintenance. However, it lacks full weather sealing, so it might not be ideal for harsh environments.

The lens is relatively lightweight and compact for its range, enhancing its usability and making it easier to handle during extended shooting sessions. It has a minimum focusing distance of 280 cm (110.2 inches), which is typical for lenses in this category. The filter size is 95mm, which might be slightly larger than average, potentially making accessories more expensive. This lens strikes a balance between performance and portability, making it a good choice for amateur photographers looking to explore telephoto photography without breaking the bank.

The Canon EF 70-300mm f/4-5.6 is a versatile telephoto zoom lens that offers a good focal length range from 70mm to 300mm, making it suitable for capturing distant subjects like wildlife, sports, or concerts with your Canon EOS Rebel T7. Its variable maximum aperture of f/4 to f/5.6 means it performs best in decent lighting conditions but might struggle a bit in low light or when shooting fast action without extra lighting. The built-in 3-stop image stabilizer helps reduce blur from hand shake, which is especially helpful at longer zoom distances.

Autofocus is driven by Canon's USM technology, known for being fairly quick and accurate, though it might not be as fast as higher-end lenses designed for professional sports or wildlife photography. The lens has a compact and lightweight design, weighing just over 1.3 pounds, which makes it easy to carry during outings. However, it lacks advanced weather sealing, so caution is advised in rough or wet conditions. The lens also benefits from special lens coatings to reduce flare and ghosting, improving image clarity.

The build quality is solid for its price, making it more suited to hobbyists or enthusiasts rather than professionals who need rugged and fast lenses. This lens is a solid choice if you want an affordable, lightweight telephoto zoom with decent image stabilization and autofocus for everyday nature, portrait, or event photography, but it may fall short in very low light or demanding shooting environments.
