This circular fisheye lens produces images with an angle of view of 180° when attached to a full-frame digital or 35mm film SLR camera, but becomes a 16mm fisheye when attached to our selection of four-thirds cameras. This is a professional-quality lens with dust and water proofing, low dispersion ED elements, and terrific contrast and sharpness.
Front cap and rear cap.
Full circle can only be captured with "full frame" 35mm format digital SLR and film SLR cameras.
