The 16mm f/2.0 ED AS UMC CS Lens for Sony E Mount from Rokinon is a manual focus wide-angle 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.

Q: 1. does it crop in with a7sii?

A: I bought it and returned it right away, I did not noticed it is not full frame. There is no reason to buy a lens that you have to modify your settings to be able to use it and also you will not use the full benefit of that sony's full frame sensor

Q: 2. Just purchased the Rokinon 16mm F/2.0 with Pentax K mount for my Pentax K-5 IIs body. With the aperture ring set to A, and setting to AV (also B, TAV modes), cannot get F stop to F2 (only goes to F4). Any suggestions? Already have an F4 lens, so getting to F2 is important. Thanks!

A: I believe the lens is defective. I would recommend contacting customer service to get a replacement.

Q: 3. Hello Good evening I would like to know if this lens is compatible with the Canon 7D Mark II , let me know as soon as possible.

A: Hi Sheilan,I use this lens with my Canon 7D Mark I, not the II. It works perfect with the I, but I am unaware of the II, I assume it would be just fine. The only thing you have to consider is that the 7D has the APS-C sensor and this lens is meant for UMC. The only thing this does when using this lens on the 7D is make the effective focal length 16mm*1.6 = about 25mm. So when this lens is used with the 7D consider it a 25mm focal length lens. Otherwise it works just fine and has been a great lens for me so far. Note that it is all manual too.

Q: 4. Hi, will this lens fit on Canon EOS 800D?

A: Yes

Q: 5. Is this lens (Rokinon 16mm) compatible with a Nikon D90?

A: Yes.

Q: 6. Greetings,Will this lense mount on Canon EOS (Rebel T3i)? I understand it is manual focus, I suspect manual exposure as well?much thanks,phil g

A: Yes, the Rokinon 16mm f/2.0 is compatible with the Canon EOS Rebel T3i, and will be a fully manual lens, including focus and exposure.

Q: 7. I see this lens is made for APS-C sensors so why does it say 25.6mm in 35mm format. I would think that since it is designed for a smaller sensor you would not have to multiply the 1.6. In other words if I use this on my Canon 7d is it 16mm or 25.6?

A: Manufacturers almost always state a lens focal length at 35mm. So, it's in reality 25.6mm on a 1.6 crop sensor. I'm using it on the 7D as well. Unfortunately, due to the totally manual properties of the lens, the camera shows no info on what the actual focal length is...Doesn't show any info AT ALL, at least not on my 7D body. Takes beautiful astronomical shots tho, extremely low to no coma.

Q: 8. Does this work with the d3400?

A: I use it frequently on a D3300, since it's almost the same camera I would safely assume it does.

Q: 9. I have the CANON EFs24mm STM that I use for Landscapes, is there an major increase in field of view with the 16mm, comparing to the 24mm field of view ?

A: That lens, the EF-S 24mm, is giving you over 38mm on a crop sensor, without knowing field of view, I'm not sure what you would end up with. I'm no expert on this, but I believe Canon always gives focal length in 35mm equivalent. But even at that length, you could use it for astrophotography, less field of view.

Q: 10. hello! does this lens cover APSH sensor like the 1dxii 4k 1.4 crop?

A: No, sorry it will not work perfectly. In fact, it would not work without severe vignetting. We are also of the opinion that it will not even mount on the camera since EF-S lenses are blocked from mounting on an EF mount cameras.
