TTArtisan 10mm f/2.0 Overview This 10mm f/2.0 Lens from TTArtisan is made for mirrorless camera bodies with a Sony E-mount. It offers a dynamic ultrawide angle view that is equivalent to 15mm in a full-frame camera body. It features two aspheric elements for outstanding corner-to-corner sharpness, plus two high index elements for high color transmission with minimal chromatic aberrations. It is an ideal lens choice for landscapes, architecture, starry skies, and environmental portrait photography. The f/2.0 aperture allows a lot of light to enter, providing an advantage when shooting in low-light environments and night scenes. This manual-focus lens has a clicked aperture ring, and the barrel features a built-in hood. An included adapter allows 72mm filters to mount to the front of the lens.
