Rokinon 12mm T3.1 Cine DS Fisheye Overview

The 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens for Nikon F Mount from Rokinon is a lens optimized for digital cinematography and as such provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with follow focus accessories. Also, focus, aperture, and depth of field markings are on the side of the lens to aid focus pullers who typically operate on the side of the camera. Aperture is measured in absolute T-stops to provide accurate and consistent exposure across lenses and color rendition is matched with other Rokinon cine lenses for consistency.

This fisheye lens provides a 180º diagonal angle of view on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any application. The T3.1 maximum aperture is effective in low light situations and enables some measure of shallow depth of field control. 

The lens' optical design consists of 12 lens elements arranged in 8 groups including three elements made of low dispersion ED glass and two aspherical lens elements to minimize coma and chromatic aberrations. Highly effective nano crystal anti-reflection (NCS) coating applied together with UMC coatings improve light transmission and reduce ghosting. Its internal focus system does not extend the front elements during focus and minimizes the effects of lens breathing.

This Nikon F Mount manual focus lens optimized for digital cinema provides a de-clicked manual aperture for smooth and silent adjustment and unified focus and aperture gears for use with a traditional follow focus. Also, focus, aperture, and depth of field markings are on the side of the lens to aid focus pullers who typically operate on the side of the camera. Aperture is measured in absolute T-stops to provide accurate and consistent exposure across lenses and color rendition is matched with other Rokinon cine lenses for consistency.
An ultra wide-angle fisheye lens with a 12mm focal length on full-frame cameras and an 18mm equivalency when used on APS-C and Super 35mm format cameras. Its distorted perspective is useful for interiors, landscapes, group shots and many creative wide-angle applications.
Extra low dispersion and aspherical lens elements reduce aberrations for sharp, color-accurate imaging.
Nano crystal coating and ultra multi-coating on the lens elements improves light transmission and reduces ghosting and flare.
Sturdy metal barrel with removable petal-shaped lens hood.

question

Hi There,Does anyone know of a good MATTE BOX solution for the Rokinon 12mm Cine DS Fisheye Lens?(I know typically with wide angle lenses, they run into vignetting problems if the Matte Box isn't wide enough.)Does anyone know of a good Matte Box that works great with this lens?Additionally, do you know if that same Matte Box will also work for the Rokinon Cine DS 14mm Lens?In advance, thank you for your help and for your recommendations. I really appreciate it!
Asked by: Tyler
This lens is too wide to be used with a matte box without any vignetting.

What would be the focal length on a Panasonic GH4 ...

What would be the focal length on a Panasonic GH4 with a .71 metabones adapter?
Asked by: Matthew
No matter what you do to this lens, it's focal length will never change; it will always be a 12mm. To get the equivalency FOV (Field of View) of a full frame sensor (a format you are not shooting in) multiply 12mm x 2 x 0.71 = 17.04mm or 92.95° FOV.

I have a D90 and a D5000. Will this lens dit?
Asked by: Marion
This lens is compatible with the D90 and D5000 since both Nikon cameras use a Nikon F Mount. You won't have auto focusing.

question

How does this lens work on lowlight?
Asked by: Pedro
For a 12mm lens that works with full frame cameras T3.1 is about as fast as you will get with a Cinema Lens. Your overall low light performance will depend more on the camera you are using and how high you can push the ISO on it.

question

How does it compare to theRokinon 12mm f/2.8 ED AS fullframe Fisheye Lens (https://<a href= http://www.bhphotovideo.com/c/product/1089938-REG/rokinon_12m_e_12mm_f_2_8_ed_as.html target= _blank >www.bhphotovideo.com/c/product/1089938-REG/rokinon_12m_e_12mm_f_2_8_ed_as.html</a> - wich I have in canon-mount version, a very good copy and that I use very, very often) but consider to change for the E-mont version. -Exept I now see ths new other one.(T3.1 might be the same as f2.8).I have not found any comparison study jet. THANK YOU !I shoot at 5.6/8 with my actual lens, max app is not my concern but corner-sharpness and rendition of people. Fully correctet anty-fisheye effect lenses do not render people as I like with my Rokinon 12mm 2.8)?
Asked by: Alain
The more expensive cine lens has the Dual Side markings, focus and aperture gears plus the coatings that are supposed to match the others in the set. Otherwise the lens performance will be comparable.

Asked by: Tyler
The answer to your question depends on the lens and what sensor size you are using for there is no universal matte box solution for ultra wide lenses. If you are using a 12mm Fish Eye on a Full Frame camera, no matte box will work. You might be able to use a 4x4 or larger filter holder. If you are using a 12mm on a MFT camera, you might be able to use a normal 4x4 matte box.
