Amazon has the Rokinon 8mm f/3.5 HD Fisheye for Canon for $199.00. This is the newer “HD” version of this popular lens, which features a detachable lens hood for full-frame shooters to get the widest field of view — close to, but not quite circular.
You can see some fun and creative photos taken with the 8mm f/3.5 fisheye in the Flickr group for this lens.
This is a Amazon Lightning Deal that expires at 3 PM ET.
