Samyang has announced the first of the 8 new lenses they have promised would arrive by Q2 of 2019, the XP 10mm f/3.5. The world's widest rectilinear prime lens for full frame cameras with a claim of being “distortion free”.
The Samyang XP 10mm f/3.5 has been designed to meet the demands of high megapixel sensors and 8K video. This new lens has a 130° angle of view on full-frame DSLRs.
Lens construction consists of 18 elements in 11 groups, with 7 special optical elements to keep image quality consistent from the center to the edges. There are 3 aspherical elements, 1 high-refractive element and 3 extra-low dispersion elements specifically designed to minimize distortion.
