Samyang's cinema 20mm for MFT — the VDSLR version with geared focus ring and T-stop marking.
The Samyang VDSLR 20mm T1.9 ED AS UMC is a cinema-adapted version of Samyang's 20mm f/1.8 stills lens for Micro Four Thirds. The VDSLR designation indicates cinema-specific modifications — geared focus ring, de-clicked aperture, and T-stop marking. On MFT, 20mm provides a 40mm equivalent normal perspective ideal for narrative video work.
Optical performance is derived from the proven Samyang 20mm stills lens. Sharpness is good from T1.9. The T-stop marking ensures consistent exposure across takes. The geared focus ring enables follow-focus system compatibility. The VDSLR modifications are functional cinema additions to solid underlying optics. UMC coatings reduce flare.
Micro Four Thirds mount. Filter thread is 77mm — large for MFT. Weight is approximately 485 grams. Build quality adds cinema-grade geared rings to the stills lens barrel.
