Samyang 12mm f/2.8 ED AS IF NCS UMC Fisheye Lens for Sony Alpha Mount (Full Frame Lens)
The 12mm f/2.8 ED AS IF NCS UCM Fisheye Lens for Sony from Samyang provides a 180º diagonal angle of view on full-frame cameras for a ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any photographic application. The f/2.8 maximum aperture is effective in low light situations and enables some measure of shallow depth of field control.
The lens' sophisticated optical design consists of 12 lens elements arranged in 8 groups including three elements made of low dispersion ED glass and two aspherical lens elements to minimize coma and chromatic aberration. Highly effective nano crystal anti-reflection (NCS) coating applied together with UMC coatings improve light transmission and reduce ghosting. Its internal focus system enables its compact design and keeps the front element from extending during focus.
This Sony FE Full Frame mount lens is manual focus lens but due to its featured AE chip provides focus confirmation in the camera's viewfinder and enables the use of Auto exposure mode and P/A/S/M modes. It offers a wide, easy to grip focus ring for smooth manual control and bright aperture, distance and depth of field markings on its metal barrel. A removable petal-shaped lens hood is included.
