Samyang 35mm f/1.2 ED AS UMC CS Review

The Samyang 35mm f/1.2 ED AS UMC CS is a fast prime lens aimed at APS-C and Micro Four Thirds mirrorless systems. With its bright f/1.2 aperture, it offers substantial light-gathering ability and shallow depth of field potential, making it suitable for portraiture, low-light shooting, and creative bokeh work. The 35mm focal length (equivalent to roughly 52mm on APS-C or 70mm on MFT) sits in a versatile range between standard and short telephoto.

At just over $300, this Samyang slots into the budget-conscious segment of fast primes. The ED (extra-low dispersion) glass aims to control chromatic aberration, while the UMC (ultra multi-coating) designation targets flare and ghosting resistance. As with many Samyang lenses, expect fully manual focus and aperture control, which appeals to deliberate shooters but may not suit fast-paced or video-centric work without focus aids. Build quality and optical performance in this price bracket typically trade some refinement for affordability, so this lens is best understood as a manual-focus option for those prioritizing speed and price over autofocus convenience.
