Ultra wide-angle mid-range lens. It has a fixed focal length of 8 mm and provides a 180° field of view. Designed for full frame matrices, available in modifications for Canon (EF mount), Nikon (F mount), Pentax (K mount), Samsung (NX mount), Sigma (SA mount) and Sony / Minolta (A mount) systems. It does not have an autofocus motor, its role is played by a “screwdriver” drive.

Everything is relative: interchangeable lenses for cameras from third-party manufacturersLenses from alternative brands: money down the drain or an increase in image quality?

Short description:

The model allows you to create unique panoramic images, and can also be successfully used in scientific photography. The new lens produces round images with a 180-degree field of view (when used with a film or full-frame DSLR camera). The main distinguishing features of the novelty are the maximum aperture of F3.5, a small minimum focus distance of 13.5 cm and the ability to shoot at a scale of 1:4.6. The lenses of the objective are made with ultra-multilayer coating, which prevents glare and reflections, and elements made of low dispersion glass (SLD, Spcial Low Dispersion) effectively correct chromatic aberration. Behind the last lens of the lens there is a holder for a gelatin filter.

The lens comes in a kit for Canon EF, Konica Minolta AF, Nikon AF, Pentax AF or Sigma AF mounts.
