Laser Drilled Pinhole Lens body cap for all Sony A Mount Alpha and Minolta AF mount cameras. This will not fit the 4/3 mirrorless NEX E mount cameras. I do have E mount pinhole body caps available 
Pinhole size is 0.3mm. This is the optimum size for this focal distance and provides the best sharpness, color saturation, and contrast. These are scientific grade apertures and have been utilized by universities and laboratories. The second photo shows the pinhole at 800x under the microscope.
Compare prices, this is the highest quality at an affordable price so get creative and discover the amazing world of pinhole photography.
