This Vivitar 7mm f/3.5 Fisheye Lens is suitable for both artistic and technical photography. Extreme-wide angle lenses are pleasingly distorted in a hemispherical projection, resulting in an image that looks like the eye of a fish. This is a diagonal fisheye lens for APS-C sensor cameras; it does not produce a circular image.
Best suited for APS-C sized sensors
180° diagonal angle of view
Multi-coated glass reduces flare and aberrations
