Carl Zeiss has said it will produce a Canon-mount version of its 18mm F3.5 lens. The Distagon T* 3.5/18 super-wide angle lens has previously only been available in the ZF and ZK mounts for Nikon and Pentax cameras, respectively. A Canon-mount version of the lens is being shown at the Photo Imaging Expo 2009 show in Tokyo and will be available 'towards the end of the year,' the company said.
