This exciting prime provides ultra wide-angle coverage up to 113° angle of view which is the widest in its class. The tiny size & light weight match perfectly with mirrorless cameras and are suitable to use with gimbals. 2 aspherical elements plus 3 extra-low dispersion elements successfully correct the chromatic aberration, realize a close-to-zero distortion & deliver a corner to corner sharpness.
The 9mm f/2.8 Zero-D is only compatible with crop sensor Sony cameras, and will not provide full sensor coverage on full frame models.
