Nortlight Images posted an interesting review about the Samyang/Rokinon 12mm f/2.8 ED AS IF NCS UMC Fisheye Lens for Canon, a pretty interesting manual focus lens at an affordable price.
In the conclusion the reviewer writes:
From an image quality point of view I’ve very little to quibble about. The lens is robustly constructed and the addition of the padded bag for it most welcome.
The f/2.8 lens gives a nice bright image in my viewfinder, although manually stopping the lens down and not having any aperture information (Canon EF) may cause some difficulties if you are not used to manual lenses.
Going to f/5.6 was enough to sharpen up the edges of the frame a bit, and gives me so much depth of field that the only reason to check the focus settings was to make sure I’d not nudged the focus when changing aperture or vice versa. Read the review…
