Canon has responded to Nikon’s push into higher quality tilt shift lenses with two new lenses announced today.
A remarkable 17mm f/4 TS-E tilt shift but with protuberant front element which means filters are not possible. Maybe at last I will have a wide angle for my Canon 1DMIII that I will love!
A revamped 24mm f/3.5 II tilt shift which accepts an 82mm filter.
More information on perspective control (tilt-shift) lenses here.
These come after Canon introduced a revamped EF 24mm f/1.4L II lens late in 2008 which hopefully will provide the resolution required for the 21mp full frame cameras. Of course this one is not a tilt-shift lens but does have a nice wide f/1.4 aperture for narrower depth of field and low light conditions.
