The Canon EF 90-300mm f/4.5-5.6 USM is a versatile telephoto zoom lens that has garnered attention for its performance across various photography genres, including wildlife, sports, and even portraiture. With a zoom range that allows for detailed captures at a distance, it appeals to those who are looking to expand their creative horizons without breaking the bank.
The lens features a compact and lightweight design, making it a good option for photographers who are often on the move. The exterior is made of durable plastic, which helps keep the weight down, but you may find it lacking the premium feel of metal-bodied lenses. The lens incorporates a rotating zoom mechanism that feels smooth, but some users may prefer a push-pull zoom, especially in fast-paced situations.
In terms of image quality, the Canon EF 90-300mm delivers satisfactory results. At 300mm, you can expect decent sharpness across the frame, although there could be some softness at the edges, especially when shooting wide open at f/5.6. Chromatic aberration can also be noticeable, particularly against high-contrast backgrounds. Overall, it offers good performance for the price, particularly for casual shooting.
Equipped with Canon's Ultrasonic Motor (USM), this lens features fast and quiet autofocus, which is a significant advantage for wildlife and sports photography where you can't afford to miss the perfect shot. In low-light conditions, however, the autofocus may struggle, requiring the photographer to manually assist at times—a worthy consideration for night-time or dimly lit environments.
Designed for the Canon EF mount, this lens is compatible with a wide range of Canon DSLR cameras, making it a suitable choice for those already invested in the Canon ecosystem. Keep in mind that on crop-sensor bodies, the effective focal length becomes even longer due to the crop factor, which can be beneficial for telephoto applications.
The Canon EF 90-300mm f/4.5-5.6 USM is a solid entry-level telephoto option that balances performance and affordability. While it may not compete with more expensive lenses in terms of image quality, its lightweight design and fast autofocus make it a great choice for photographers looking to capture distant subjects without carrying a heavy load. Overall, it is a practical lens for casual photographers, enthusiasts, and anyone looking to add a telephoto option to their kit without overspending.
