The Canon RF100-500mm F4.5-7.1 L IS USM is a super-telephoto zoom lens designed for Canon's EOS R series mirrorless cameras. It offers a versatile focal length range from 100mm to 500mm, making it ideal for wildlife, sports, and distant subjects. The aperture range of F4.5-7.1 is decent, though it may struggle in low-light conditions compared to lenses with larger maximum apertures. However, the Optical Image Stabilization with up to 5 stops of shake correction helps mitigate this by allowing for slower shutter speeds without blur.
The lens features three image stabilization modes, providing flexibility depending on the shooting scenario. Autofocus is fast, smooth, and quiet thanks to the Dual Nano USM technology. The minimum focusing distance of 3 feet allows for relatively close-up shots, adding to the lens's versatility. Build quality is robust, consistent with Canon's L-series, and includes weather sealing, making it durable for outdoor use.
The lens is compatible with Canon's full-frame mirrorless cameras, including the EOS R, RP, R5, and R6. Its maximum aperture of F7.1 at 500mm may not be ideal for all lighting conditions, and the lens is relatively heavy at 3 pounds, which could be a consideration for handheld shooting over long periods. Despite these drawbacks, the Canon RF100-500mm F4.5-7.1 L IS USM remains a versatile and durable choice for telephoto photography.
The Sigma 150-600mm 5-6.3 Contemporary DG OS HSM Lens for Canon is a versatile telephoto lens that offers a wide focal length range of 150-600mm, making it suitable for wildlife and sports photography. One of its strengths is its lightweight and compact design, which enhances portability and ease of use, especially for extended shooting sessions. The water and oil repellent coating on the front glass element is a practical feature that aids in maintaining the lens surface, providing durability and easier cleaning.
Additionally, it includes a 95mm filter size and has a notable minimum focusing distance of 280 cm (110.2 inches), giving it an ability to capture distant subjects clearly. However, the maximum aperture range of f/5-6.3 might be a limitation in low-light conditions, as it may require higher ISO settings or slower shutter speeds to achieve proper exposure. The lens does feature Optical Stabilization (OS), which helps to mitigate camera shake and improve image sharpness, beneficial for handheld shooting at longer focal lengths.
It is compatible with Canon EF mounts, ensuring it fits well with Canon Rebel cameras. The Hyper Sonic Motor (HSM) provides fast and quiet autofocus, which is advantageous for capturing moving subjects. Despite its strengths, the lens lacks advanced weather sealing, which might be a concern for photographers shooting in harsh environments. This lens is ideal for Canon Rebel users who prioritize a long zoom reach and portability, but it may not be the best choice for those needing a fast aperture or robust weather resistance.
The Canon EF 100-400mm f/4.5-5.6L IS USM is a versatile telephoto zoom lens that covers a wide focal range from 100mm to 400mm, making it suitable for wildlife and sports photography. The maximum aperture of f/4.5-5.6 is decent, although it might struggle in low light conditions compared to faster lenses.
This lens excels with its image stabilization, which has two modes to reduce camera shake, crucial for handheld shooting at longer focal lengths. The lens is compatible with Canon EF mounts and can also be used with extenders to increase its range further, adding flexibility for photographers needing extra reach. Autofocus performance is enhanced by the ultrasonic motor (USM), providing fast and silent focusing, which is beneficial for capturing fast-moving subjects without disturbing them.
The build quality is robust, with durable construction, but it lacks advanced weather sealing that would protect it in harsh environments. Additionally, the use of Fluorite and Super UD-glass elements helps minimize chromatic aberrations, ensuring sharp and clear images. Weighing 3.04 pounds, it is relatively heavy, which can be a drawback for prolonged handheld use. Measuring 7.44 x 3.62 inches, it’s also quite large, which might be cumbersome for some users. This lens could be a great choice for Canon SLR users looking for a high-quality telephoto zoom lens with a good balance of performance and versatility, though it may not be ideal for those needing a lightweight and highly portable option.
