Question 1

Is the Samyang 14mm f/2.8 ED AS IF UMC good for astrophotography?

Accepted Answer

Yes — the f/2.8 maximum aperture at 14mm is genuinely useful for Milky Way and star-trail shooting on a full-frame Nikon F body. Because the lens is manual focus, you simply turn the focus ring to the infinity mark and fine-tune in live view; there's no hunting autofocus to slow you down in the dark. The wide field of view also lets you capture large portions of the night sky in a single frame.

Question 2

Does the Samyang 14mm 2.8 have autofocus on Nikon F cameras?

Accepted Answer

No — the Samyang 14mm f/2.8 ED AS IF UMC is a fully manual-focus lens with no autofocus motor at all. It won't drive AF through a Nikon body's screw-drive either. For landscape and astro work this is rarely a limitation, but if you need AF for action or events, you'll want to look at a different option.

Question 3

What is the difference between the Samyang 14mm f/2.8 and the Rokinon 14mm f/2.8?

Accepted Answer

Optically they are the same lens. Samyang manufactures the optics, and the Rokinon and Bower versions are simply rebadged for different markets. If you see 'Rokinon 14mm f/2.8 IF ED UMC' listed, the glass, barrel construction, and performance are identical to the Samyang version. Choose whichever copy is in the best condition.

Question 4

Will the Samyang 14mm f/2.8 Nikon F fit on a full-frame camera?

Accepted Answer

Yes — the lens is designed to cover a full-frame image circle. On a full-frame Nikon F body you get the full 14mm field of view (roughly 115°). On a crop-sensor (APS-C) Nikon body the effective field of view narrows to around 21mm equivalent, which is still wide but loses some of that dramatic ultra-wide character.

Question 5

Is buying a used Samyang 14mm f/2.8 worth it?

Accepted Answer

For most landscape and astro shooters, yes. The all-manual design has no autofocus motor to fail, so the main things to check on a second-hand copy are the condition of the front element and smooth travel of the focus ring — both easy to verify from item photos. Every copy sold here comes with a minimum 12 months warranty and has been individually inspected, so you're not buying blind.

Question 6

What is the closest focus distance of the Samyang 14mm f/2.8 ED AS IF UMC?

Accepted Answer

The minimum focus distance is 0.28 m (28 cm). That's close enough to get dramatic environmental context around a nearby subject — a useful trick for adding scale and depth in landscape compositions, where you might place a rock or plant in the extreme foreground while keeping distant mountains sharp.
