Insanely Huge Camera Lens
The super multiple layers of coating reduces ghosting and flare while providing high qualities of image from the large aperture. The lens hood which is specifically designed for this lens blocks out rays of extraneous light. A filter size of 72 mm can be inserted at the back of the lens with the options of utilizing a polarizing filter which can be used in conjunction with the internal rotation mechanism. The Li-on battery is dedicated to the BP-21 system and can be used to power the zoom features and AF operations. The battery is conveniently built into the lens barrel, making it easy to access. Focusing focal lengths and distances can be viewed on the LCD panel that is built into the lens.
The device is to be used with Canon digital SLRs. The Ultra telephoto zoom lens allows the user to objects at a close or far distance. The speedy aperture allows the user to take many snapshots in a very short amount of time. The dedicated attachment option allows the user to automatically focus at the 1000 mm focal length.
