Canon EF 400mm f/4
DO IS USM (multi-layer Diffractive optical elements)
Image Stabilizer USM AutoFocus Lens
| Canon's breakthrough
multi-layer diffractive
optical lens technology
provides photographers with
superior super-telephoto
performance in a smaller and
lighter design with enhanced
correction for chromatic
aberrations. Canon also
added their highly effective
Image Stabilization system
that gives the equivalent
effect of a shutter speed
two stops faster. And, it's
built it to Canon's
professional standards with
fast AF, full-time
mechanical focus and dust
and water-resistant
construction. |
