Designed for up to 8K cine-style image capture, the Canon EF-mount 15mm T2.6 Cine Lens from IRIX incorporates multiple internal and external design features. This compact 15mm lens will produce a classic wide-angle look and is compatible with full-frame 35, Super35, RED DRAGON 6K, ARRI ALEXA, APS-C, Micro Four Thirds, Super 16, and additional sensors. 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, and four seals protect against inclement weather and dust. To help eliminate aberrations and distortion, the IRIX 15mm T2.6 Cine Lens is constructed with 15 optical elements including three HRI (high refractive index), two ED (extra-low dispersion), and two ASP (aspherical) elements. An adaptive focus ring delivers smooth focusing whether used manually or with a lens motor. This lightweight, aluminum/magnesium alloy lens has 180° of focus and 75° of iris rotation, and an 86mm front filter thread. The Canon EF-mount 15mm T2.6 Cine Lens includes front and rear caps.

Cinematic Look
The IRIX Cine 15mm is a wide 43.3mm full-frame lens that uses 15 optical elements, including three high refractive indexes (HRI), two extra low-dispersion glass (ED), and two ASP (aspherical) 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.
Wide-Angle Lens
Creates an expansive angle of view for classic wide-angle shots or a panoramic 100° viewing angle in a 1.39:1 widescreen format.
Ready for Any Weather Condition
Rain or shine, the rugged and durable construction of the IRIX Cine 15mm guarantees that you can keep working with whatever the weather throws at you. The lens is resistant to rain, sand, and dust, so you can take it for your next adventure in a desert or jungle if your camera can handle those environments. Engraved markings on the lens have been filled with UV-reactive paint, so filming in difficult lighting conditions becomes much easier.
Functionality and Innovation
All IRIX cinema lenses have very similar dimensions and weight, allowing for quick and easy lens changes without needing to change the rest of your setup. The product is equipped with a Magnetic Mounting System (MMS) that lets you connect accessories such as magnetic filters from the Irix Edge lineup or an optional lens hood.
Cine Standards
The IRIX Cine 15mm was designed per the standards of the professional film industry, the result of a combination of traditional lens solutions and modern innovation. This 15mm has a front filter thread size of 95mm and geared 0.8 MOD rings, which ensures compatibility with most accessories available on the market.
This compact aluminum-magnesium alloy lens has a front external diameter of 95mm to fit most matte boxes and accessories, plus a front Magnetic Mount System (MMS) for rapid filter and hood replacement.
Adaptive Gear Ring
The adaptive gear ring is an innovative function that you will love, no matter if you are a pro or an amateur. The ring has been designed to keep the lens housing sleek and user-friendly when operated manually without any compromises when you want to use your favorite cine gear.
Compact Design
This compact aluminum-magnesium alloy lens has a front external diameter of 95mm to fit most matte boxes and accessories, plus a front Magnetic Mount System (MMS) for rapid filter and hood replacement.
Magnetic Mount System
All IRIX Cine lenses with the Magnetic Mount System are compatible with the separately available IRIX Edge MMS filters and IRIX MMS lens hood. The IRIX Edge magnetic filters have a unique threadless design, so you can be sure that everything stays clean and ready for action. The MMS filters can be stacked together, enabling you to not only freely combine them but to save space when stored. All the IRIX Edge MMS filters are made of hardened optical glass (SR) with a multilayer, antireflective nano-coating that makes them easy to clean.

Would this 11mm be equivalent to a 24mm on ...

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

What changes and how does the " An adaptive focus ring" adapt from manual to follow focus use?
Asked by: Rich
On the IRIX 15mm T2.6 Cine Lens, the focus ring does not change, but rather, it is conducive to both manual use (by hand) and for use with a follow focus (motorized or manual), due to it's ergonomic design, equipped with 0.8 pitch gear teeth.
