The Samyang 8mm f/3.5 Asph IF MC Fisheye CS DH Lens features a detachable lens hood (DH), otherwise is the same (optically and mechanically) as the non detachable hood version.
Available initially in Canon mounts, it is a high quality Fisheye type ultra wide angle lens for Canon digital SLRS / DSLRS with an APS-C size Cropped Sensor (CS).
It is a “full frame” diagonal fisheye lens for APS-C DSLRs, meaning that the image it produces fills the frame on APS-C cameras. It produces an immense field of view - 180 degrees on 1.5x crop sensors, or on 1.6x crop sensors such as Canon EOS APS-C DSLRs produces 167 degrees.
On Full frame cameras, it produces a vignetted image, which is almost circular with the lens hood detached. This effect is required for user wanting the biggest image / field of view for panoramic software on full frame cameras, and one of the reasons Samyang produced this removable lens hood version. The Samyang 8 mm Fish-eye lens is ideal for creating panoramas and 360 virtual tours, including full 360 degree images with the correct hardware and various 3rd party panoramic software supplied by other vendors.
