The Canon EF 28-200mm f/3.5-5.6 USM is a versatile zoom lens that offers a range of focal lengths from wide-angle to telephoto, making it an appealing option for photographers who want an all-in-one solution. With its 7.1x zoom ratio, it caters to various photography styles, from landscapes to portraits and even some wildlife photography.
One of the standout features of this lens is its Ultrasonic Motor (USM) autofocus system, which allows for fast, quiet focusing, a feature that is especially beneficial for capturing stills as well as video. The lens is compact for its zoom range, making it a good choice for travel or for photographers who prefer lightweight gear. The build quality is solid, featuring a plastic body that is lightweight yet feels reasonably durable.
However, the lens does have its drawbacks. The variable aperture can be limiting, particularly at longer focal lengths where the maximum aperture opens to f/5.6. This can hinder performance in low-light situations and may require the use of higher ISO settings to obtain a proper exposure. Additionally, the image quality, while decent, does not quite match that of higher-end, prime or specialized zoom lenses, particularly in terms of sharpness and distortion at certain focal ranges.
Furthermore, some users may find the lens lacking in weather sealing, which can be a drawback for outdoor photographers who frequently shoot in challenging weather conditions. It's also worth mentioning that although autofocus is quick, it might hunt in low-contrast situations, which can be frustrating when trying to capture fast-moving subjects.
The Canon EF 28-200mm f/3.5-5.6 USM is a solid choice for photographers seeking a versatile zoom lens without breaking the bank. While it has some limitations in low light and overall optical performance compared to more premium options, the benefits of convenience and portability make it a valuable addition to the kit of any enthusiast looking for flexibility in their photography.
