Canon EF 400mm f/4 DO IS II USM Telephoto Lens
The technical details behind this lens
Canon EF 400mm f/4 DO IS II USM Telephoto Lens offers an excellent optical layout. The gapless dual-layer diffractive optics are employed within the lens construction to make a smaller, lighter 400mm option with enhanced correction for chromatic and spherical aberrations. Aspherical and UD elements are used to further reduce distortions. A Sub Wavelength Coating contributes to increased clarity and contrast. Complementing the sophisticated optical design, a four-stop-effective Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different ways of shooting. Perfectly positioned as a versatile option for sports and wildlife photographers, the lens high-performance attributes and natural handling render this a viable telephoto option for a variety of applications. It also features a rounded nine-blade diaphragm that contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
