Expressive and bright landscape photography
With an open aperture of f/1.8, the Samyang 20 mm full frame lens is the ideal companion for astro and landscape photography. It guarantees good results even in poor lighting conditions. The object in focus is beautifully set in scene, while the background (at open aperture) is immersed in a wonderfully soft bokeh. This full-frame wide-angle lens is not only suitable for indoor photography, but also for concerts, landscape and street photography.
Optical processing
The Samyang 20/1.8 DSLR is a fast super wide angle lens designed specifically for use with full frame cameras. The 20 mm/1.8 lens is equipped with the best optical technology Samyang has to offer. The wide-angle lens is coated with Samyang's Ultra Multi Coating UMC. The combination of coating, the two aspherical glass elements (ASP) and the three extra low dispersion glasses (ED) reduces chromatic aberrations to a minimum and prevents unattractive light scattering. The glass construction consists of 13 glasses, which are divided into 12 groups and provide sharp images from the center to the edge of the image.
The 7 blades of the iris ensure almost circular highlights when the aperture is open, while crystal-clear, star-shaped highlights appear when the aperture is closed. The lens is compact and robust and is therefore the perfect companion, even when things get a little rougher.
Advantages of a full frame lens on a camera with APS-C sensor
Save time in post-processing: A variety of lens defects such as distortion, blur, or vignetting appear on the edges of the image. If you use a full-frame lens on a camera with an APS-C sensor, these areas will not be used in the first place. Thus, you automatically get the maximum quality and no additional time for correcting lens errors needs needs to be invested in post-processing.
