The Canon EF 15mm f/2.8 was a fisheye lens produced by Canon from 1987 to 2011. The lens was compatible with all EF camera bodies but only intended for full-frame configurations, as the fisheye effect is much less pronounced with a cropped sensor (APS-C).

In 2010 Canon announced the upcoming EF 8–15mm f/4L Fisheye USM which replaced the EF 15mm f/2.8.[2]

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.

gollark: No.

gollark: I was thinking about red sandstone and skyblocks, but that sounds also horrible.

gollark: That sounds aesthetically horrible.

gollark: I'm trying to design a nice-looking AE2 controller room, any ideas?

gollark: I wonder if I can somehow add mana distribution to my piping system.
