The Canon 15mm f/2.8 full-frame EF Fisheye is the best fisheye I’ve ever used. It is super-sharp, never fuzzy in the corners like Nikon fisheyes can be on a bad day.
The Canon 15mm fisheye fills the full frame with curviness and waviness, seeing 180º from corner to corner. Groovy!
Lens will be supplied with front and back cap and protective lens pouch.
