Samyang AF 35mm F1.8 FE

Reviewers found a sharp centre from f/1.8, with the edges and corners catching up by around f/4, which is a good result at this size and price. The linear STM focuses quickly and silently and tracks well enough for stills and casual video.

The optical compromises show up wide open: heavy corner vignetting that only clears by about f/5.6, visible longitudinal colour fringing on high-contrast edges, and flare when the sun is in or near the frame. The plastic barrel is well finished, but it does not feel as solid as metal-bodied primes.

Owners mostly bought it as a walk-around lens for compact bodies and are happy with that choice: it is light, focuses quietly, and the sealing gives peace of mind outdoors. Many say they prefer it to Sony's pricier FE 35mm F1.8 for size alone.

Recurring complaints are purple fringing in backlit scenes, strong vignetting without a profile, and occasional AF hesitation in dim light. Firmware updates need the separate Lens Station dock.
