2004: Canon has today announced the new EF 70 - 300 mm F4.5 - F5.6
DO IS USM zoom lens, the first zoom lens ever to use Diffractive Optical
(DO) elements. These new elements, seen previously only in the 400 mm
F4.0 DO lens enable this 4.2x telephoto zoom lens to measure less than
10 cm long at the 70 mm position. On a digital SLR with an 1.6x FOV crop
such as the EOS 10D this lens has an effective field of view of 112 to
480 mm, on the new EOS-1D Mark II the lens has an effective field of view
of 91 to 390 mm. The lens will be priced at $1,299 (US) / €1,299
(EU).
