Samyang AF 14mm F2.8 FE

Tests agree that the centre is sharp from f/2.8 but the outer field stays soft until about f/8, which limits it for wide-open astrophotography on high-resolution bodies. Raw files show around 3.8% barrel distortion and over 2 EV of corner shading at f/2.8; both correct cleanly with profiles, and lateral CA is moderate.

Build quality and the price-to-performance ratio get consistently good marks. Autofocus is described as reasonably quick and quiet for a lens where focus rarely needs to move. Faster or sharper alternatives, such as Sigma's 14mm f/1.8 Art or Laowa's manual 15mm f/2, cost more or are much larger.

Owners mostly use it for travel, real estate and stopped-down landscapes and value having autofocus and EXIF at 14mm for the money. The solid metal feel and the compact size compared with DSLR-era 14mm lenses come up often.

Common complaints are soft corners wide open, copy-to-copy variation in centring, and the lack of a filter thread. Some early owners reported AF quirks that later firmware updates fixed.
