The Theia Technologies CS-Mount 1.3mm Fixed Manual Iris Lens features a fixed 1.3mm focal length that provides an ultra-wide 135° field of view with less than 3% residual barrel distortion. Using Theia’s patented Linear Optical technology, this wide-angle lens corrects barrel distortion optically and does not require a custom dewarping or an image stitching algorithm which is usually associated with wide-angle lenses. This lens is designed for CS-mount cameras and supports 1/4″, 1/3″, and 1/2.5″ image sensor sizes.
