An extreme super-telephoto USM lens, ideal for capturing smaller subjects over long distances.
Four-Stop Image Stabilizer
Image Stabilizer (IS) technology allows the use of shutter speeds up to four times slower than normal, with no perceptible increase in image blur. Automatic panning detection turns off IS in either the horizontal or vertical direction when following moving subjects.
Aspherical, Fluorite, UD and Super-UD elements
For optimum visual performance, the lens incorporates four types of special optical elements: aspherical elements to correct spherical aberrations, and Fluorite, UD (ultra-low dispersion) and Super UD elements to eliminate secondary chromatic aberrations. The result is crisp, high-contrast and undistorted image quality, all the way to the edge of the frame.
