Designed for up to 8K cine-style image capture and covering up to full-frame size sensors, the Sony E-mount 11mm T4.3 Cine Lens from IRIX incorporates multiple internal and external design features. This 11mm lens will produce a classic wide-angle look or up to a 123° viewing angle in the 2.39:1 widescreen format, depending on your camera's sensor. 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 11mm T4.3 Cine Lens is constructed with 16 optical elements in 10 groups including four 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 an 86mm front filter thread and includes a lens hood in addition to front and rear caps.

Cinematic Look
The IRIX Cine 11mm is a wide 43.3mm full-frame lens that uses 16 optical elements, including four high refractive index (HRI) and two extra low-dispersion glass (ED) 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 T4.3 maximum aperture and can be stopped down to T22.
Wide-Angle Lens
Creates a moderate wide angle of view for classic wide-angle shots or a super-panoramic 123° viewing angle in a 2.39:1 widescreen format.​
Ready for Any Weather Condition
Rain or shine, the rugged and durable construction of the IRIX Cine 11mm guarantees that you can keep on working with whatever 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, which allows for quick and easy lens changes without the need 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 11mm was designed in accordance with the standards of the professional film industry, being the result of a combination of traditional lens solutions and modern innovation. This 11mm has a front filter thread size of 95mm and geared 0.8 MOD rings, which ensures compatibility with most accessories available on the market.
Adaptive Gear Ring
The adaptive gear ring is an innovative function 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 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.

Does anybody have any insight on this lens vs a Venus laowa 12mm zero d 2.9?
Asked by: Todd
The IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) is slightly wider but lets less light enter. The Venus Optics Laowa 12mm T2.9 Zero-D Cine Lens (Canon EF) (B&H# VE1229CC) is sharper and faster.

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