TTArtisan A31B-Z
Shooting at 7.5mm f/2, this manual-focus lens produces a full-frame circular fisheye or a complete APS-C fisheye, backed by 2 LD and 3 high-index elements for contrast. A 4.9-inch minimum focus distance and an included front cap that crops vignetting into a clean circle add further creative flexibility. It best serves budget-conscious photographers needing dramatic perspective distortion for architecture, interior, and macro work, where it scores 63.1.
Про цей Lens
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.
