Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
The lens does not feature optical image stabilizer. It is a significant disadvantage for a lens of such class - the need for image stabilization only grows with increasing of focal length. In order to obtain sharp images with this lens, you will need to use a tripod or shutter speeds not longer than 1/800 second (at focal length of 800 mm) which may require in some cases increasing the ISO setting and will lead to noisy images.
