Samyang's manual-focus ultra-wide for Sony E APS-C — same as Fuji X version, 18mm equiv for astrophotography.
The Samyang 12mm f/2.0 NCS CS for Sony E is the Sony mount variant of the hugely popular APS-C ultra-wide prime. Providing 18mm equivalent on Sony APS-C E-mount, it is one of the most popular astrophotography lenses for the A6000 series.
Optically very good — identical to the Fujifilm X version. Sharp from f/2.8 with impressive centre performance at f/2. Minimal coma makes it excellent for star photography. NCS nano coating reduces flare. Manual focus only with smooth damped ring.
Sony E mount with no standard filter thread — curved front element. Manual focus only — no electronic contacts on most versions. Approximately 260g. Minimum focus distance 20cm. All-metal construction. Also sold as Rokinon 12mm f/2.
Very common used and excellent value. Check for smooth focus ring. The Sony E mount version pairs perfectly with A6000/A6100/A6400 for astrophotography. No AF or EXIF on most versions — note settings manually. The go-to budget astrophotography lens for Sony APS-C.
