Samyang repair

Fast autofocus lenses from the South Korean company Samyang are extremely interesting and slightly underrated. The company has journeyed from fully manual budget lenses to fully compatible autofocus models, and they've succeeded. Modern AF lenses don't just have autofocus; they're equipped with “trendy” ultrasonic motors of their own design. Considering the excellent image quality, I'd place them alongside both branded primes and general-purpose zooms. Of course, there's a bit of hardware "tar" in the honey: reliability isn't quite their strength yet. Judge for yourself - common failures include: Ultrasonic motor failures Stuck apertures Splitting in half at the lens mount However, other issues are very rare, and the ones that do occur are usually easy to fix successfully. Below is a full repair report based on working with five (!) identical Samyang AF 35/1.4 FE lenses - all apperaed for service at the same time.
