This dynamically wide 7.5mm f/2 Fisheye Lens from TTArtisan is a lens that fills the image area of an ASP-C image sensor from corner to corner, but also acts as a circular fisheye when used on a full-frame format image sensor. When used on a full-frame image sensor camera, the circular fisheye image is heavily vignetted on all four corners. The included front cap has a unique design that crops slightly further into the image area to create a fully circular image with a cleaner perimeter. The lens design renders a 180° angle of view to produce a distinct visual appeal characterized by dramatic distortion and a creative depiction of space, which helps to make wide and innovative landscape and interior photos. The characteristic fisheye distortion and close 4.9" focus distance also lends itself to surreal and exaggerated portraiture and close-up photography.

The included rear-mount ND1000 neutral density filter adds a 10-stop increase to extend the exposure time for dramatically blurred moving elements in landscapes, and for astral photography.
