Canon Patent Application: Canon EF 10mm 2.8 This patent application is really focused on the Canon EF 11-24mm, however there was another embodiment that may sometime make it as a lens. With a back focus of 38mm, this lens is most certainly an EF lens, and the embodiment in question is: Focal length: 10.30 mm F number: 2.88 Half angle of view: 64.54 Image height: 21.64 mm Lens length: 124.58 mm Back focus: 38.00 mm However since the actual patent itself discusses a zoom lens, this sounds like something Canon added into the application as a complete afterthought.
