Firsts edit
This lens broke new market ground in several respects:
- It is the first Canon EF lens to offer 180° circular fisheye images for full frame image sensors.[1] Note Canon had a circular fisheye lens for the FD mount.[2]
- It is the first zoom fisheye lens for any DSLR to offer a full 180° angle of view in both circular and rectangular image formats.[3]
- It is the first lens by any manufacturer to offer a 180° angle of view for APS-H (1.3x crop factor) bodies.[1]
- Also, it is the first zoom fisheye lens to offer a 180° angle of view on both full-frame and cropped bodies.[1]
