Specification :
The RF200-800mm F6.3-9 IS USM lens has a 4x zoom that covers from telephoto to super-telephoto ranges, allowing you to capture a subject at a distance to fill the entire frame. The availability to back-off to 200mm at its wide end means you can easily include a subject’s surroundings. The 800mm maximum tele capability is outstanding when photographing wild birds, wild animals, and other subjects — and delivers powerful visual “telephoto compression, in stills and video content. This 4x zoom range gives great flexibility, when working with subjects whose movements are unpredictable as you are able to continue shooting or recording video — even if the subject comes closer.
Several features are incorporated into the lens to enhance the operability for photographers. A Focus/Control Ring on the lens barrel can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more — or act as a manual focus ring. Two conveniently located Lens Function Buttons allow you to program specific functions to occur at the press of either button, such as immediate access to Eye Detect AF, changes to exposure settings, and more***. The RF200-800mm F6.3-9 IS USM is also designed for smooth and balanced zoom operation, so the central balance of the lens doesn’t shift when the total length of the lens changes.
*** Lens Function button settings are performed in the camera’s “Customize Buttons” menu. Range of possible functions varies, depending upon camera model being used. Only one function can be applied at a time, and each button performs the same function.
