New Rokinon 16mm f/2.0 Wide-Angle Lens for APS-C and Micro Four Thirds

Share

Rokinon has announced a new 16mm wide-angle manual-focus lens for DSLR and mirrorless cameras in both the APS-C and Micro Four Thirds formats. As a standard wide focal length with an f/2.0 maximum aperture, it is bound to please APS-C and Micro Four Thirds shooters who have been looking for just such a fast and versatile optic.

The 16mm f/2.0 ED AS UMC CS lens is available for Nikon, Canon, Pentax, and Sony Alpha APS-C DSLRs and Canon EF-M-mount, Fujifilm X-mount, Sony E-mount and Samsung NX-mount APS-C mirrorless cameras. It is also available for Panasonic and Olympus mirrorless cameras with the Micro Four Thirds mount.

On Canon cameras it provides a 35mm equivalent focal length of 25.6mm and on the other APS-C format cameras, both DSLR and mirrorless, 35mm equivalency, as mentioned, is 24mm. This is the first design of such a lens from Rokinon, and a 24mm equivalent f/2.0 for APS-C format should certainly be appreciated by landscape and interior shooters or anyone who would like to utilize the extra speed and shallow depth of focus that the f/2.0 maximum aperture provides. On the Micro Four Thirds mount, the 35mm equivalent focal length is 32mm; still well within the wide-angle classification.  

The minimum focus distance of the lens is 7.87”, ideal for perspective-bending close-ups. Its optical construction comprises 13 elements in 11 groups, including two aspherical elements and one extra-low dispersion element to help minimize chromatic aberrations and produce sharper overall imaging. Rokinon’s UMC lens coating is applied to reduce reflections and minimize flare and ghosting. A petal-shaped hood is included to help deflect stray light.

Approximately 4.5” long for the mirrorless versions and 3.5” for the DSLRs, and weighing a bit more than a pound, it’s no pancake but the build is solid. An all-metal mount sits stably on the camera, its wide, rubber focusing ring has a nice feel and rotates smoothly, and the distance scale and aperture are clearly marked. The front filter diameter is 77mm. 

Below are a few sample images taken with the 16mm f/2.0. However, I am looking forward to having some quality time with this lens so keep an eye out for our complete hands-on review in the near future.

It's great to see this 16mm prime lens for APS-C sensors. When your hands-on review is published, I am interested in seeing examples of flare and ghosting control while shooting into the sun. Also, is this an 8 blade diaphragm? Curved blades? What can we expect for a sun-star in a landscape photograph? Also, I would appreciate seeing good examples of out-of-focus specular highlights in a variety of lighting conditions, and from f/2 to f/5.6.

Christopher:

Thank you for your inquiry, I’m also looking forward to trying the new Rokinon 16mm f/2 lens. I’ll be sure to make a few attempts at creating a sun-star and will take a good look at the out-of-focus highlights. To answer your question, there are 8 rounded diaphragm blades in the Rokinon 16mm f/2 and the minimum aperture is f/22, so it should have no problem creating a sunburst of 8 rays. We will see if the rounded blades serve as well as straight blades for this application.

All the best,

John Harris

Is there a depth of field scale on the lens? I miss hyperfocal focusing (without consulting a chart)!

From the versions of the lens I have seen, yes it does have the distance scale to use for hyperfocal focusing. However each camera brand mount (Nikon, Canon, Sony etc) can vary and it may not be on each one. Let me know what mount you want to purchase the lens in and I can further confirm for you.

It would be interesting to see a (macro) shot at about 7.9 inches and f/2.0. Also, an indoor architectural shot. In my work those are the two things I want a short lens for. That is, where I want a broad area, but there is no place to move back to, in order to get more in the picture and were I want excellent definition at close range.

This is great. There are very few wide primes for aps-c. And this one looks very good.
