2. 180 degrees of diagonal angle of view for 8mm of local distance for APS-C for the first time in a fish-eye lens.
3. Corrects optical aberrations using a complex aspherical lens and produces a high resolution and high contrast at the center of the lens as well as the periphery, with a fully open aperture.
4. Petal type hood and multi-coating design suppresses flaring and ghost images.
5. Robust durability with a high strength aluminium frame.
You can easily take photographs without installing an additional adaptor, by mounting the lens directly to the camera.
