Last week, Samyang released a super-fast 35mm f/1.2 for mirrorless APS-C and 4/3 cameras. Today, we get two wide-angle manual focus lenses—20mm T1.9 ED AS UMC for cine, and a 20mm F1.8 ED AS UMC for photo.

The 20mm T1.9 ED AS UMC is part of the full frame sensor line and features an ultra-wide lens with an incredible close focus of 0.2m (around 8"). Samyang says, "The bright T1.9 aperture secures a fast shutter speed even under the restricted lighting conditions to offer best quality images."


Designed for DSLR and mirrorless cameras, it showcases two aspherical lenses and three extra-low dispersion elements​.​

The lens is fixed with a smooth focus ring and is accompanied by a circular aperture with seven blades (both click-less). Designed for DSLR and mirrorless cameras, it showcases two aspherical lenses and three extra-low dispersion elements. Similar to the 35mm f/1.2, Samyang promises it will "minimize aberration and unnecessary light dispersion, delivering high resolution from the center to the corners of the image."

For convenience, the distance scale and T numbers are marked on both sides of the lens when filming and a petal lens hood is included. As a consideration to fill the gap between 14mm and 25mm, the 20mm will come in Canon EOS, Nikon AE, Pentax K, Sony alpha, Canon M, Fujifilm X, Samsung NX, Sony E, FT, and MFT mounts.

  • Aperture range: T1.9 - T22
  • Optical construction: 13 elements in 12 groups, 2 aspherical lenses
  • Min. focusing distance: .2mm (~8")
  • Filter size: 77.0mm
