Samyang's budget manual focus 14mm f/2.8 — the go-to astrophotography lens for beginners worldwide.
The Samyang 14mm f/2.8 ED AS IF UMC (2010) became the default recommendation for budget astrophotography. Its f/2.8 aperture at 14mm full-frame ultra-wide, combined with remarkably low cost, made it accessible to astronomers and landscape photographers who could not justify premium alternatives.
Good centre sharpness for astro — some coma in extreme corners at f/2.8 but acceptable for the price. UMC multi-coating. Mustache distortion requires software correction. Manual focus with hard infinity stop — essential for night sky work.
Canon EF mount. Also available in Nikon F, Sony A, Sony FE, Pentax K, MFT. Bulbous front element — no front filter thread. No electronic contacts — no EXIF data. Manual focus only. 560g.
Very common and cheap used. Check for decentring by shooting a flat wall. The AF version and MF II version improved coatings. The Sigma 14mm f/1.8 Art is dramatically superior but costs 5x more.
