- Canon EF 24-105mm f/4L IS USM Camera Lens
Canon EF 24-105mm f/4L IS USM is an easy-to-use standard zoom lens that can embrace a large zoom area ranging from 24mm wide-angle to 105mm of focal length telephoto, and its Image Stabilizer Technology steadies camera shake up to three stops. The lens is capable of having a constant maximum f/4 aperture throughout zoom range. A ring-type ultrasonic motor drives autofocus very fast, and in near silence. The lens integrates a Super UD (ultra-low dispersion) glass and aspheric lens elements to remove secondary chromatic aberrations. The Circular aperture provides beautiful images and pleasing background blur. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.
Product Features in Detail
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.
Lightweight and versatile
The EF 24-105mm f/4L IS USM offers a 4.3x zoom ratio, from wide angle to medium telephoto. It is highly portable, weighing just 670g.
The f/4 maximum aperture of the EF 24-105mm f/4L IS USM is fixed throughout the lens' focal-length range, so shutter speeds will not change as the lens is zoomed.
The EF 24-105mm f/4L IS USM features Canon's three-stop Image Stabilizer (IS), making it ideal for handheld work. IS permits the use of shutter speeds up to three stops slower than normal, with no perceptible increase in image blur from camera shake.
Super UD and aspherical lens elements
The lens incorporates a Super UD (ultra-low dispersion) glass element to eliminate secondary chromatic aberrations. Aspherical lens elements correct for spherical aberrations. The result is crisp, high-contrast, undistorted optical performance throughout the zoom range, without colour fringing at high-contrast edges.
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.
Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.
Smooth background blur
A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background
