These are the best Rokinon lenses for astrophotography when you want fast apertures, low coma, and repeatable manual focus for Milky Way landscapes, star trails, and tele-nightscapes—and here’s what to look for as you buy: favor speed (ƒ1.4–ƒ2.8) with tight off-axis control (low sagittal coma/astigmatism), a long, smooth focus throw with a reliable infinity position (tape it once found), mild field curvature, manageable vignetting that flats can fix, strong flare resistance for moon/lanterns, filter friendliness (front threads vs bulbous fronts that need holders or rear gels), consistent color across a set, and weight you’ll actually hike with; for timelapse/video, declicked apertures and cine gears help, and on AF lenses check for “astro focus” modes and firmware support—then pair everything with a sturdy tripod, heater/hand warmers for dew, and your camera’s IBIS/interval tools. Full-frame wide heroes: the Rokinon 14mm ƒ/2.8 (manual or Cine T3.1) remains the budget classic for sweeping cores and tight interiors (profile the mustache distortion), while the Samyang/Rokinon XP 14mm ƒ/2.4 cleans up corners and boosts micro-contrast; the Rokinon 20mm ƒ/1.8 (and 20mm T1.9 Cine) is a sleeper for “stars + subject” at faster shutters, and the AF 24mm ƒ/1.8 FE adds an astro-focus aid and tiny weight for hike nights; Sony users chasing speed can also look at the AF 14mm ƒ/1.8 FE for brighter subs with disciplined corners. Core FF normals for tracked panos and night streets: the Rokinon/Samyang 24mm ƒ/1.4 and 35mm ƒ/1.4 (also in Cine T1.5 DS/DSX) give prime-like light gathering with long throws—stop 1/3–2/3 stop if your copy needs edge tightening. Tele-nightscapes and constellation fields sing on the Rokinon 135mm ƒ/2 (or 135mm T2.2 Cine): razor sharp wide open with smooth bokeh for compressed stars, airglow bands, and moonlit ridgelines. APS-C/MFT standouts: the tiny Rokinon/Samyang 12mm ƒ/2.0 NCS CS (E/X/MFT) is a legend—light, filter-threaded, and low coma—while DSLR APS-C shooters can reach for the 10mm ƒ/2.8 (rectilinear ultra-wide) or 16mm ƒ/2.0 (fast wide with great micro-contrast); cine versions (12mm T2.2, 16mm T2.2) keep gear positions consistent for follow-focus nights. Practical buyer tips: pick focal length by scene—14–16mm for galactic arches, 18–24mm for foreground storytelling, 35mm for tracked mosaics, 85–135mm for constellations/nebula fields; choose threaded fronts (12/2, 20/1.8, 24/1.8 FE) if you rely on NDs/mist or like anti-dew filters, budget a 100mm holder for bulbous wides, test your copy for infinity accuracy in daylight at 10× live view, and standardize filter sizes where possible. Shooting tips: start around ISO 3200–6400, use the “500-rule” on full frame (“300-rule” APS-C) to cap trailing, focus via magnified live view on a bright star then tape the ring, shoot wide open or stop 1/3–2/3 stop for cleaner corners, capture a low-ISO foreground for blending, disable IBIS on a locked tripod, and pack a soft heater to fight dew. Whether you’re mapping the galactic core above sea stacks, stitching tracked mosaics, or compressing Scorpius over desert peaks, the best Rokinon astro lenses combine fast glass, disciplined corners, and repeatable mechanics—so your night files are sharp, bright, and easy to process.
