Samyang AF 35mm F1.8 — Editorial Review

The Samyang AF 35mm F1.8 is a compact, lightweight autofocus prime for Sony E-mount full-frame, undercutting Sony's own 35mm f/1.8 on price by a wide margin. It's pitched as the small, affordable everyday 35mm — and reviewers largely agree, with caveats wide open.

Featured Video Review

Samyang AF 35mm f/1.8 'P' camera lens review
Christopher Frost · "Samyang AF 35mm f/1.8 'P' camera lens review" · Watch on YouTube

Small, stealthy, and a strong value

Dustin Abbott notes a diminutive 210g body with a metal mount and weather sealing, a fast and quiet focus motor, and smooth video focus pulls. SLR Lounge highlights that stopping down to f/2.8 transforms it into a corner-to-corner sharp performer at roughly half the price of Sony's equivalent. In Christopher Frost's review — featured above — he weighs that value against its wide-open compromises.

Honest cons

  • Soft, low-contrast wide open. At f/1.8 the center is only acceptable, with reduced contrast; it sharpens up markedly by f/2.8.
  • Chromatic aberration. Visible purple/green fringing wide open, usually correctable in software.
  • Plastic-heavy build. Solid for the price but engineered plastics rather than premium materials.
  • Focus breathing. Noticeable breathing and only average AF speed in continuous shooting.

Where this lens fits

  • Sony shooters wanting a light, cheap 35mm for street, travel, and everyday carry.
  • Content creators who value the quiet, smooth focus for video on a budget.
  • Photographers who shoot f/2.8 and down and want that strong stopped-down sharpness for less money.
  • Not those who need peak wide-open performance, premium build, or the fastest autofocus.
