Canon 70-300mm f/4.0-5.6 EF IS USM

• Distance information collection system
• 3-speed image stabilization system
• Not compatible with EF1.4x II and EF2x II extenders

From the manufacturer's press release:

The latest 3-stop equivalent image stabilization greatly compensates for camera shake and delivers highly accurate autofocus. Replacing the popular EF 75-300 mm f/4-5.6 IS USM, the world's first interchangeable lens with Image Stabilization (IS), this lens was developed specifically for the demanding outdoor and sports photographers. image quality when shooting in manual mode.

Image stabilizer

Image Stabilization (IS) technology can greatly reduce motion blur caused by camera shake during shooting. The EF 70-300 mm f/4-5.6 IS USM features Canon's latest 3-stop Image Stabilizer, one stop more than its predecessor. This allows you to shoot at slower shutter speeds (up to 3 stops) and still take sharp photos. Typically, when shooting handheld at 300mm at 1/500s, you can achieve similar image quality at shutter speeds as low as 1/60s. This opens up the widest possibilities for shooting in low light conditions.

The gyroscopic sensor detects unwanted vibrations and causes the group of corrective lenses to move in a direction perpendicular to the optical axis. This allows you to adjust the light flow and restore the correct position of the image on the sensor or film.

The EF 70-300 mm f/4-5.6 IS USM lens supports two modes of image stabilization when shooting still subjects. Mode 1 allows you to stabilize the image about the horizontal and vertical axis. When shooting against a background of moving objects in mode 2, correction of the direction of movement of the background is disabled, and thus the effect of moving the object across the frame is prevented. The image stabilization system is automatically disabled when the camera is mounted on a tripod, which prevents feedback between the vibrations of the image stabilization system sensor and the stabilizer motor.

Excellent autofocus

The EF 70-300 mm f/4-5.6 IS USM uses an ultrasonic microdrive for fast and near-silent autofocus. Thanks to a clear and precise fixation of the lenses during torque, the correct focus on the object is ensured on the first try. The high-performance processor and advanced autofocus algorithm significantly improve autofocus speed compared to the predecessor model.

The locking mechanism of the zoom lens focus ring allows you to lock the zoom lens at a wide angle of view. Thus, the lens occupies the smallest space, which makes it easy to store and move, and also prevents damage to the glass when carrying the camera with the lens extended on the neck strap.

beautiful blurred background

The EF 70-300 mm f/4-5.6 IS USM is equipped with a circular aperture electromagnetic diaphragm (EMD). This allows you to create photos with a beautiful, even blurry, background by highlighting the object at a large aperture.

Image quality

By refining the Super Spectra lens coating and lens shape, Canon's developers have been able to reduce the ghosting and flare that are most common in digital cameras due to reflection from the image sensor. By increasing light absorption, the coating reduces the reflective effect of the lenses, resulting in brighter, sharper images in natural colours.

When attached to the EOS 20D and EOS 350D cameras, the focal length is converted according to the 35mm film equivalent range of 112-480mm.

EOS system

The EF 70-300 mm f/4-5.6 IS USM lens transmits distance information to the camera, making it compatible with the E-TTL II metering system when shooting with flash mounted on later digital cameras such as the EOS-1 D Mark II N and EOS 5 D. When using a lens with Canon EX Speedlite series flashes, distance information is transferred to the flash algorithm, greatly improving exposure metering.

Accessories for the EF 70-300 mm f/4-5.6 IS lens include the ET-65B lens hood and the LP1222 lens case. In keeping with Canon's "Kyosei" philosophy (living in harmony with the environment), Canon lenses are made only from lead-free glass.

The following EOS series cameras also support the E-TTL II system: EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D, EOS 350D, EOS 30V and EOS 300X
