Review on Samyang SYHD8M-C 8mm f/3.5 HD Lens with Detachable Hood for Canon by Sirious Cavalli

I have the Canon version. This is a fully manual lens. This means that even though it's APS-C, I can still use it on my full screen (images look round). Focus and aperture are set manually. You don't need to focus much in that range anyway, and depth of field doesn't seem to change much with aperture, so it mostly depends on how much light you want to let through. Image quality and sharpness are good. It has issues with glare and sometimes chromatic aberration. Another problem with this lens is that you can't use filters. This lens is absolutely more than worth its price. If you are looking for a fisheye then this lens is worth considering.
