This enables a sharp resolution with a minimum of color blurring.
Extra-low dispersion (ED) glass is used for thoroughly eliminating the chromatic aberration that tends to occur in super telephoto lenses. This enables a sharp resolution with a minimum of color blurring. Various types of protective coatings, prevention of reflections on the inner side of lens, and a large hood are used for rendering results with a transparency and reduced ghosting and flare. Quick AF/MF switching is also possible, and an inner focus system enables easy MF operation. The lens includes a rotating tripod seat with clip to enable speedy switching between vertical and horizontal orientations.
