Allowing you to produce unique, creative long exposures with a wide-angle perspective, this Wide Pinhole from Rising is compatible with Sony A mount cameras. The pinhole features a narrow f/168 aperture, 61° angle of view, 37mm focal length, and an aluminum alloy construction for durability as well as high image sharpness. Inherent to pinholes, the design also produces nearly infinite depth of field and the long exposure times required during shooting are ideal for blurring motion.
