You and this lens should log some quality time together. With a fixed f/4.0 maximum aperture throughout its zoom range, you'll have excellent light sensitivity even at full magnification. Canon's acclaimed image stabilization technology improves low-light performance, enabling you to use shutter speeds much slower than you'd ordinarily employ. This lens will give you great, artifact-free close-ups, and expansive-yet-vibrant panoramas while you're documenting that once-in-a-lifetime road trip. This could end up being your main "go-to" glass.
An ultra-quiet USM motor gives quick and accurate autofocus response while shooting fast and unpredictable subjects. And, like all of Canon's L-series lenses, the optics rank among the industry's best. Aspherical elements and Super-UD glass mean faithful image transmission with minimal color fringing or blurred edges.
