The 16mm f/2.0 ED AS UMC CS Lens for Samsung NX Mount from Samyang is a manual focus wide-angle prime lens compatible with APS-C format mirrorless digital cameras. It provides an 83.1° angle of view which translates into a 35mm format equivalency of 24mm. A fast maximum aperture of f/2.0 is effective in low light shooting and provides shallow depth of field. With two aspherical lens elements and one extra-low dispersion element, chromatic aberrations are minimized and sharp, color-accurate images are the result. UMC lens coating facilitates even light transmission and reduces ghosting and flares.

Related Questions and Answers

Q: 1. will it work on a Sony a7s II?

A: This will be compatible with the Sony A7Sii.

Q: 2. Please confirm that this lens is chipped for auto exposure with Nikon cameras. The photos show that it has the electrical contacts on the lens mount, and the aperture ring has a Nikon type AI coupling ridge, but there isn't any mention of this in the lens description.

A: That lens does not have electronic connections. You can use the camera in Aperture priority or manual.

Q: 3. Will this lens work for a Canon 60D? If not, does anyone know of a lens that will and do the same thing?

A: This lens is compatible with the Canon 60D. The 60D has an APS-C sensor and is compatible with all lenses that are designated EF and EF-S

Q: 4. Is the lens hood that comes with this reversible so I can screw it on the lens backwards?

A: yes it is reversible

Q: 5. Will this lens work well with the T5i for daytime landscape and astrophotography?

A: Yes, if you are comfortable with manual focus. If the T5i has focus peaking (which I doubt), it would be easy. If not, you can use the LCD screen (not as easy). I use it on my Olympus (with adapter), which has focus peaking and that works well.

Q: 6. Can this be used with a canon T2i (550d)?

A: The manual focus Samyang 16mm f/2.0 ED AS UMC CS Lens for Canon is compatible with the Canon T2i.

Q: 7. Is this lens compatible with a Canon SL1?

A: This is an ef-s lens. Canon USA says sl1s are compatible with all ef lenses, including ef-s. I use this lens on canon t3i and t3 both of which also take ef and ef-s lenses.

Q: 8. Will this lens work and fit a Samsung NX Mini?

A: No, the Rokinon 16mm f/2.0 ED AS UMC CS Lens for Samsung NX Mount will not mount on the Samsung NX Mini Mirrorless Digital Camera. The NX Mini uses the NX-M-mount that is smaller than the standard NX-mount.

Q: 9. Will this work with a D7000? I had an issue with the new nikon 10-20mm wide angle, and want to confirm I will have full functionality.

A: Yes, this lens will work on the D7000

Q: 10. Can I use this lens wide-open for astrophotography? Any smearing of stars or other problems at f2?

A: Short answer: Yes . All lenses when fully open will introduce some distortion, so stopping it down a bit always helps. See Jerry Lodriguss' thorough article in Sky and Telescope August 2015 p. 60+. I mounted it to a Nikon D7200 piggybacked on a Meade LX90. Since the mount was in Alt-Az mode, I got field rotation with 30 second exposures. With a wedge and the LX90 polar aligned it should do just fine. Issues will be with your mount, not with the lens.
