The 12mm T3.1 ED AS IF NCS UMC Cine DS Fisheye Lens for Sony E-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 Sony E-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.

Related Questions and Answers

Q: 1. Anyone use these on D850? How do you control aperture?

A: These would work great on a D850. There is a physical aperture ring on the lens that you rotate to change the aperture.

Q: 2. are these prime?

A: Yes. All following lens are prime lens.

Q: 3. Forgive my ignorance, but do these lenses have built-in image stabilization? I'm working with a camera that does not have good sensor stabilization; therefore I'm wondering if these lenses would help at all with image stabilization.

A: No these lenses does not have image stabilization. They actually don't have any electronic devices built in, purely glass.

Q: 4. In the product highlights above, it says Covers full-frame sensors. If you use these lenses on a Sony FS700, which has a super 35mm sensor, will there be in vignetting in your video footage?

A: Full Frame sensors are nominally 24mm x 35mm in size which creates an image diagonal of 43.3mm. For a lens to cover Full Frame it must create an image at least that size in order not to vignette. Since a Super35 frame is nominally 24mm x 14mm in size with an image diagonal of 27.31mm, you can see a lens that covers Full Frame easily covers the Super35 frame.

Q: 5. Are these lens in the bundle anamorphic or spherical?

A: The Rokinon Cine DS Lens Bundle for Sony E-Mount are spherical lenses.

Q: 6. Are these lenses for full frame sensors?

A: All of the lenses are full frame except the 16mm which is Super35/APS-C.

Q: 7. Will these lenses work with the five axis stabilization of the a7s ii?

A: Yes they will. You just have to be sure to manually change the compensation when you swap lenses. Its pretty easy to do by adding the stabilizer compensation tile to the function menu

Q: 8. Will this work in a Canon 7D Mark II?

A: Since the Canon 7D Mark II has a APS-C sensor, this entire set can be used with confidence that there will be full sensor coverage with no onerous vignetting.

Q: 9. do it work on APS-C Canon?

A: Rokinon Cine DS 6 Lens Kit with Canon EF Mount will work on Canon Cameras with a APS-C size sensor.

Q: 10. Will these lenses work with a Sony PXW-FS5 XDCAM Super 35 Camera or do I need an adapter?Thanks !

A: No adapter required. These are Sony E-Mount as is the PXW-FS5 so they should work like a charm.
