COLOGNE, Germany -- A year and a half ago,zoom lens with a built-in 1.4X extender. But since then, there's been nary a peep.
Well, there's a peep now, Canon shooters jealous of Nikon's 200-400mm will be pleased to know.
The plan is to release it this year, said Mike Owen, communications manager for Canon's professional imaging department in Europe. He spoke at a Canon press conference yesterday at the Photokina show here.
But Owen was quick to add a caveat: "We're anticipating that, but we don't know," he said.
Canon and partners have been putting the lens through its paces at the Olympics and other major sporting events, he said. The qualitative feedback so far has its autofocus working just a tad slower than Canon's 400mm F2.8 fixed focal length lens, he said.
Canon hasn't detailed the mammoth lens yet, Owen said it's expected to be a bit heavier than the EF 400mm F/2.8L IS II, but that's still a lot:to a bit more than 8 pounds in 2010.
A bit more detail is visible at Canon's booth at Photokina. Sandwiched between the EF 400mm f/2.8L IS II (13.5 inches long, not including lens hood) and EF 500mm f/4L IS II (15.1 inches long), it looks to be about 14.5 inches long.
Judging by the focus-range limit option, the minimum focusing distance is 2 meters. The focus range on the lens can be set for 2m-6m, 5m to infinity, or the full range.
The lens also comes with the power focus (PF) mode for smooth motor-driven focus changes during video shooting.
The lens has something of an unsightly bulge near its camera mount, but it's for good cause: a housing for a flip-out element that extends the lens range 1.4x to 280-560mm but dimming the lens to a maximum f-stop of f5.6.
The telephoto extender is technology brought to the photography line from Canon's broadcast lens business.
Supertelephotos of this class are expensive as well as bulky. Canon's 400mm f/2.8L II costs $11,500, and the 500mm f/4L costs $10,500.
