A bright and versatile ultra-wide prime, the Pentax K-mount 14mm f/2.8 ED AS IF UMC from Samyang features a bright f/2.8 maximum aperture and is well-suited for subjects ranging from landscape to architecture to astrophotography. The optical design incorporates a pair of aspherical elements and three high refractive index (HR) elements, which control spherical aberrations and distortion. Additionally, two extra-low dispersion elements are used to reduce color fringing and chromatic aberration for improved clarity and color accuracy. An Ultra Multi-Coating has also been applied to limit flare and ghosting for improved contrast and color rendering in strong lighting conditions. This manual focus prime has an 11" minimum focusing distance and also features a built-in petal-shaped lens hood to guard against flare and protect the front element.

Q: 1. Is this compatible with my sony a7rii?

A: Yes, the Samyang 14mm f/2.8 ED AS IF UMC Lens for Sony E Mount is compatible with the Sony A7rII.

Q: 2. Does the lens fit canon t5i?

A: Yes. However, due to your smaller sensor size it will not act like a 14mm. To find out how Ed lenses will act on a crop body, take the size and multiply by the crop size... 14 x 1.6= 22.4mm. So 22 1/2 mm is how this lends will act on your t5i.

Q: 3. will focus peaking work on the Nikon D850 with this lens?

Q: 4. does the lens fit on a Canon 6D?

A: Yes. This lens is commatible with both full frame cameras (i.e. Canon 6D) and cropped sensor Canon cameras.

Q: 5. Is this lens compatible with filters? If so what diameter?

A: Unfortunately, due to the round convex shape of the outer front element in the Samyang 14mm Ultra Wide-Angle f/2.8 IF ED UMC Lens to assist in correcting distortion and other optical problems, the extreme convex shape prevent standard filters (or lens caps) to be used with the lens. The lens comes with an oversized lens cap for this reason, but we do not have standard filters or filter threads designed for use with the above lens.

Q: 6. whether it will work with cannon 5d mark 3 ?

A: The 14mm f/2.8 Lens for Canon Is compatible with the 5D III.

Q: 7. Can the aperture be adjusted in 1/3 increments for Nikon version of the lens?

A: When using the Samyang 14mm f/2.8 ED AS IF UMC Lens for Nikon F, the aperture cannot be set in 1/3 increments mechanically, but when one sets the lens at the f22 auto (in red) setting, then the f stop can be electronically set at 1/3 increments.

Q: 8. Is this lens supposed to work on Nikon D7000? Because I just got it and.. it doesn't.. My display keeps blinking 'fEE'. Actually, it does work.. but only with f22??! Help?!

A: As with all Nikon F-mount lenses that have an aperture ring built into the lens, you must lock the aperture ring on the lens to its smallest setting (in this case, f/22), for the lens to be used on your camera. On the Nikon D7000 DSLR camera, you control the aperture via the control dial on the camera body, not via the aperture ring on the lens. This is indicated on both pages 26, 67, and 269 of the Nikon D7000 DSLR Camera's instruction manual.

Q: 9. Can this lens be mounted directly on the Sony Alpha ILCE-7 without an adapter?
