TTArtisan has announced a new 11mm f/2.8 Fisheye lens for full-frame Nikon F mount and Canon EF mount DSLRs. Yeah, I know, a DSLR lens in 2022! What are they thinking? Well, it looks like might be bringing out some dedicated mirrorless versions, too, although so far, it only appears to be Nikon F and Canon EF mount ones that are available – although they can be easily adapted!
The new lens offers a wide 180° field of view with an also wide f/2.8 aperture. It has a built-in lens hood and a minimum focus distance of only 17 centimetres. It contains 12 elements in 10 groups, including 4 high refractive index elements to help control distortion and spherical aberrations for improved sharpness. An extra-low dispersion element helps to reduce colour fringing and chromatic aberration.
