Question 1

What's the difference between the Samyang 14mm T3.1 and the Samyang 14mm f/2.8?

Accepted Answer

They share the same optical formula, but the T3.1 version is built for video: it has a de-clicked, geared aperture ring for smooth exposure transitions and a geared focus ring compatible with standard follow-focus systems. The f/2.8 photo version has a clicked aperture designed for stills use. If you're primarily shooting video or using a rig, the T3.1 is the one to go for.

Question 2

Is the Samyang 14mm T3.1 good for astrophotography?

Accepted Answer

It can work, but keep expectations realistic. At T3.1 it lets in less light than the f/2.8 photo version wide open — the T-stop accounts for real-world light loss through the glass, so in practice they're very close. The 14mm field of view captures a wide swathe of sky in a single frame, which is great for Milky Way shots. You'll want to use a solid tripod and shoot in bulb or timed shutter mode since there's no autofocus or image stabilisation to rely on.

Question 3

Does the Samyang 14mm T3.1 autofocus on Nikon DSLR bodies?

Accepted Answer

No — this lens is fully manual focus only. There's no electronic coupling to the camera's AF system. What you do get is a long 200° focus rotation, which makes precise manual pulling much easier than on a typical stills lens. On Nikon F bodies you'll also need to set exposure manually or use stop-down metering, since there's no electronic aperture control.

Question 4

Can I use this lens on an APS-C Nikon body?

Accepted Answer

Yes. On an APS-C Nikon DSLR the 14mm focal length gives you a 35mm-equivalent field of view of around 22mm — still wide, but not the dramatic ultra-wide effect you get on full frame. The image circle is large enough to cover both sensor sizes without vignetting.

Question 5

Is buying a used Samyang 14mm T3.1 worth it?

Accepted Answer

Absolutely, especially for a manual-focus cine lens. There are no autofocus motors or electronic contacts to wear out, so the main things to check are glass clarity and aperture blade condition — both of which are covered by the inspection process here. Every used lens sold on Camera-tweedehands.nl comes with a minimum 12 months warranty, so you're not buying blind. It's one of the safer second-hand lens categories precisely because the design is mechanically simple.

Question 6

Does the Samyang 14mm T3.1 have a built-in lens hood?

Accepted Answer

Yes — a built-in petal-style hood is integrated into the lens barrel. This is standard on most ultra-wide lenses because the front element is so large and curved that traditional screw-on filters and separate hoods don't fit. The built-in hood protects the front element and reduces flare without any extra accessories needed.
