Today Canon announced the introduction of new Tilt-Shift lenses to it’s lineup. The TS-E 17mm f/4L and the TS-E 24mm f/3.5L II.
These lenses will be available in April 2009, the TS-E 17mm will sell for $2499 and the TS-E 24mm for US$2199.

The TS-E 24mm f/3.5L II replaces the TS-E 24mm f/3.5. Both of the new lenses are L series lenses. Canon’s other two TS-E lenses, the TS-E 45mm f/2.8 and TS-E 90mm f/2.8 are not L series lenses. The new lenses are designed with UD glass to minimize chromatic aberrations and have superior coating on elements for the highest possible glare-free image quality. These lenses are compatible with the entire lineup of Canon digital SLRs.
