Samyang 21mm T1.5 AS UMC CS

The Samyang 21mm T1.5 AS UMC CS is a manual focus wide-angle prime lens tailored for APS-C mirrorless systems. It provides a focal length equivalent to roughly 31.5mm on full-frame, making it a versatile choice for documentary and cinematic work. The lens features three aspherical elements to control aberrations and geared rings for precise control of focus and the de-clicked aperture. On the used market, focus breathing and the smoothness of the manual focus helical should be assessed. SDS checks for any lateral play in the lens barrel, which can occur with heavy follow-focus use. We also verify that the UMC coatings are intact and that the de-clicked aperture moves freely throughout its range without sticking. The compact size of this lens makes it prone to impact damage, so the filter thread is also thoroughly inspected.
