The Opteka 6.5mm f/3.5 HD fisheye is an extreme wide-angle lens that produces an edge-to-edge image on an APS-C sized sensor. We know of (very few) lenses for Canon that are wider, but they are circular fisheye lenses. This lens is really, really, obscenely wide. Straight lines will appear bent, and perspective is extreme. This lens is best suited to specialty applications, like comedic perspective shots and Beastie Boys music videos.
Performance-wise, this lens performs reasonably well, considering how extreme it is. If it’s not using the same optics as the Rokinon 8mm f/3.5mm, it’s close enough that we couldn’t tell in quick comparison testing.
The lens is an EF mount, so it will fit on a fullframe camera like the Canon 5D series, but it will function as a circular fisheye (the corners of your image will remain black).
The lens is fully manual, with aperture and focus controls on the barrel. Focus is nearly irrelevant on a lens this wide, with a hyperfocal distance of about 3 feet wide open. The lens hood is detachable. The lens lacks front threads, so round filters are not an option.
This lens is designed to work with any crop-factor Canon DSLRs, such as the T-series, 7D series, 60D, 70D, etc.
