If you only have one lens in your kit, this is the one to have. Featuring a widely used range of focal lengths, superior build quality and outstanding optical performance, the EF 24-105mm f/4L IS USM is a general purpose lens that really delivers. As a standard zoom lens it offers a wide range of applications, including landscape, travel, portrait and close-up photography. Solidly built and easy to handle, the EF 24-105mm f/4L IS USM features a ring-type ultrasonic motor driven autofocus that is fast, accurate and quiet. Using the superb image stabilisation, you can control camera shake, take handheld shots in low light, and use longer shutter speeds to create beautiful motion blurs. When it comes to portrait shots, the eight aperture blades can help you craft a striking background blur to highlight your subject. Image quality is exceptional, with sharp centre and corners, well-controlled flare, chromatic aberration and vignetting, and stunning colour and contrast.
