Designed for up to 8K cine-style image capture and covering up to full-frame size sensors, the Nikon Z-mount 15mm T2.6 Cine Lens from IRIX incorporates multiple internal and external design features. This 15mm lens will produce a classic wide-angle look. External features include a 95mm front diameter, 0.8 MOD gears, luminous focus marks in feet, and a detachable 1/4"-20 support foot.

Internally, nine blades produce smooth, rounded bokeh for natural-looking out-of-focus highlights. To help eliminate aberrations and distortion, the IRIX 15mm T2.6 Cine Lens is constructed with 15 optical elements in 11 groups, including three HRI (high refractive index) and two ED (extra-low dispersion) elements. A Multi-Start Thread focusing mechanism delivers quiet, precise focusing even in wet or humid conditions or in extreme temperatures. This lens has 180° of focus and 75° of iris rotation and it incorporates an 86mm front filter thread. Four seals protect against inclement weather and dust.

The IRIX Cine 15mm is a wide 43.3mm full-frame lens that uses 15 optical elements, including three high refractive index (HRI), two extra low-dispersion glass (ED), and two aspheric (ASP) elements, to create crisp cinematic shots in resolutions up to 8K while keeping the focus breathing at a minimum. This lens features a relatively fast T2.6 maximum aperture and can be stopped down to T22.

Related Questions and Answers

Q: 1. Why no Nikon F mount then it could be adapted to more than one camera!?

A: I am sorry to say we are not aware of the reason why IRIX does not make this lens with a Nikon F mount.

Q: 2. Would this 11mm be equivalent to a 24mm on Super35 sensor, specifically the Blackmagic 6K Pro?

A: Used on the Blackmagic Design Pocket Cinema Camera 6K Pro (Canon EF) (B&H# BL6KPKCAMP) with its 1.6X crop-sized APS-C sensor, the IRIX 15mm T2.6 Cine Lens (Canon EF, Feet) (B&H# IRC15EFI) will render a field of view that is equivalent in its effective focal length to using a 24mm lens on a full frame sensor-equipped camera body. If you instead opt to use the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) with that same camera then the field of view in terms of its its effective focal length would be equivalent to using an 18mm lens on a full frame sensor-equipped camera body.

Q: 3. Would I be able to put a clip on mattbox on this lens to use a polarizer or would that vignette?

A: The diameter of the front of the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) -- not to be confused with the filter size -- is 95mm which is a very common size to which to attach a matte box. Yes, it would be possible to do so. Given the ultra wide nature of the field of view, however, there will of course be at least some amount of vignetting regardless of the size of the filter, but that is unavoidable.

Q: 4. I have a Lumix S5, could I use this lens with the ef-mount version on my L-mount with the EF-L Fusion adapter? Could it work well?

A: YEs this lens will work on the Panasonic / Leica L series line of FF camera with an L mount to EF mount adapter

Q: 5. Will this lens work with the Canon EF Lens to Micro Four Thirds T Speed Booster SUPER16 0.58x?

A: Yes, The IRIX 15mm T2.6 Cine Lens would work since the Metabones adapter supports full frame Canon EF mount lenses.

Q: 6. Is the lens mount user-swappable?

A: This lens is not user-swappable. I recommend going to Duclos Lenses for professional mount conversion and calibration. They offer the IRIX lenses in ARRI PL, Canon EF/RF, L-Mount, Micro 4/3, Nikon Z, and Sony E mounts.

Q: 7. Is this lens weather sealed?

A: There are four seals protecting against inclement weather and dust.

Q: 8. I want to mount this lens on my PL-mount ZCAM camera and on my EF-mount Blackmagic 6K Pro. Which adapter ring is best?

A: There are two options that would allow you to mount a PL lens like the IRIX 45mm T1.5 Cine Lens to your Black Magic Pocket 6K Pro. The best option is from Wooden ( BH #WO274700) which would convert your P6K to a PL mount camera. Also there are PL to EF adapters ( BH #FOPCEAAP ) that could also be an option. Please note that the IRIX lens has not been tested with the FotodioX PL to EF adapter.

Q: 9. Using this lens with Matte Box, like a Tilta Mirage, will I get some vignetting?

A: Tilta suggest not to use a lens that is wider than 25mm on a full frame sensor, regarding vignetting.

Q: 10. is this lens compatible with Black Magic Pocket Cini 4K or 6K cameras?

A: The following unit offers a micro four thirds mounting system. will not mount to a BM6k unit
