| Retail info | |
The Canon EF 15mm f/2.8 USM is Canon's only production fisheye lens; other companies make fisheye lenses for Canon though (other fisheye lenses).
The lens is only intended for full-frame bodies, as the fisheye effect is much less pronounced with a cropped sensor (APS-C).
Angle of view
The EF 15mm is a full-frame fisheye lens, not a circular fisheye lens.
This means that it provides a full 180° angle of view only across the diagonal; it does not provide a complete hemispherical view, and is not suitable for hemispherical photography.
