Quality Construction - Full body made of metal. Multi coated low-dispersion glass, anti-reflection coating, this telephoto zoom lens delivers exceptional clarity. Manual focus can gives you a total control for your photo. 【Aperture Range】 --- This is a manual zoom telephoto lens, which means that it does not have an electronic connection to control the aperture directly from the camera. The aperture setting on this type of lens is fixed at f/8.3, and this is why you are unable to change the aperture using the camera's controls. The aperture range is F8.3-16, and it automatically adjusts with the focal length. Consequently, the camera cannot set the aperture value of the manual lens, resulting in the display of F00/F-- on the camera.  【User Instraction】: This is a FULL MANUAL lens, NO Electronic Contacts, your camera will not detect the lens when mounted, that's why we can't press the shutter. Tips to use our Manual Lens: Set the mode dial to Manual (M). Manual Focus Design: As a manual focus lens, it encourages creative photography by allowing you to precisely control the focus. Compatible with Canon EOS DSLR cameras and available adapters for other mounts.
