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.

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, 75° of iris rotation, and an 86mm front filter thread, and it includes front and rear caps. Four seals protect against inclement weather and dust.

Q: 4. is it compatible with Blackmagic Pocket Cinema 6K Pro?

Q: 5. What is the difference between Firefly lens vs Blackstone lens?

A: Irix 11mm f/4 Firefly and Blackstone share the same specifications. The difference is in the build quality. The blackstone is stronger made of durable aluminum and magnesium alloy. The firefly lens is made of a lightweight ABS plastic exterior construction.

Q: 6. Is this compatible with any clamp on matte boxes or does the front piece protrude too much?

A: The IRIX 11mm T4.3 Cine Lens (Canon EF, Meters) doesn't have filter threads so there wouldn't be a way to get the adapters of the clamp on matte boxes on to the lens.

Q: 7. Since there is no Sony FE version, how will this work with a Canon EF to Sony E Metabones adapter?

A: Works well with the Metabones Canon EF/EF-S Lens to Sony E Mount T Smart Adapter (Fifth Generation).

Q: 8. Is this considered a FF lens? So on a S35 chip the focal length would be 1.5x magnification?

A: Yes, the IRIX 45mm T1.5 Cine Lens covers full frame sensors. There will be a 1.5x crop factor when using this lens on cameras with a Super35 sensor.

Q: 9. Is this compatible with an RF adapter on a Canon RF body? I read somewhere that it requires a firmware update installed by IRIX.

A: The IRIX 11mm f/4 Firefly Lens for Canon EF can be adapted to a Canon R-series mirrorless camera, but the operation would be fully manual, and there would be no EXIF data. No firmware update is needed since it is entirely manual.

Q: 10. Can the aperture be controlled with a dead adater like the FotodioX Pro TLT ROKR Tilt-Shift Adapter for Nikon F Lens to Sony E ?

A: The aperture in the IRIX 11mm f/4 Firefly Lens is only controlled electronically. So the Fotodiox tilt/shift adapter would not be able to control the aperture.

[9] Last few years I was looking for ultra-wide lens to help me in real estate photography. Sometimes the rooms to be shot were so small so I could'n use my 15-30/2.8 and I had to proceed with 16mm fish-eye. And since I've got this Irix 11/4 and made few test shots, I have no regrets. It's perfect for any tiny place and doesn't bend the walls. The lens is sharp at 4. Being swithed to f11, it doesn't need to be focused at all. What really surprised me was an ability to take street photos. Just for fun I brought this lens to a local city event and use it for candid photography. To get a good picture I had to be VERY close to the subject. And what I did find that the people don't get scary when photographer stays within 1 meter. They think the camera was pointed somewhere out. And, what is more important, you don't need to lose time for viewfinder's look and focusing, just point and shoot. 5

[11mm] Very well constructed. Maintains Rectilinear image despite the great angle of view. Resolution is as advertised, very sharp! Seems to maintain sharpness throughout the field of view, corner to corner. CA is quite low, and any residual can be eliminated in post production. The only con is that the lens is quite bulky. Comes with case, and really fancy packaging, and a built - in lens shade. Canon would do well to provide the above, especially considering their prices! 5

[T4.3] A very substantial and solidly built piece of glass. Excellent quality. The lens is very sharp with great color and contrast. If you're like me, you may need to work on your focusing skills since it's a manual focus lens. Usually not an issue because infinity covers a huge area in such a wide angle lens. Irix is very proud of their packaging but I found it pretty insubstantial. The can is very flimsy and thin. Not nearly as tough as your average coffee can. B&H might consider packaging this with a little extra padding. UPS, my least favorite carrier, was pretty rough with mine and the can was actually bent. Fortunately, the very nice semi-hard lens case that comes with the Blackstone version did a nice job of protecting the lens. If you need or just want a super wide angle non-fisheye lens, this is a great value. 5

[T4.3] I don't really see distortion, maybe need to make more pictures.Use on nikon d750. Noticed that camera got very warm taking pictures at night with exposure about 20 sec at 35 degrees celsius. 5

[Full Frame] Awesome lens for scenery, landscapes, cramped interiors ... really opens things up! Packaging was excellent, lens was inside a sturdy metal box with heavy duty foam inserts, inside a durable cardboard box, inside a padded cardboard box from B&H. This lens seems very well built, gives sharp images, and has features I wish other lens makers would use in their lenses; the hyper-focal distance scale, click stop infinity detent, and raised 'lever' on focusing ring to name a few. I would definitely recommend this lens as an inexpensive, lightweight, super-ultra-wide-angle lens !!! 5

[43.3 mm] After 3 months of waiting I received the lens and i had tried it for few shots. the lens is tack sharp with little distortions and some CA. This super wide angle has great colors and good contrast the only negative is that I recieved the lens with scratched cap which makes it like a used one. 5

[T4.3] This super wide lens is great for the price! Focus lock is very nice too. Highly recommended. 5

[T4.3] The Irix 11mm lens produces professional level images.� I’ve owned 5 similar focal length lenses from both Sigma, Nikon, and Zeiss.� This lens is by far the best.� If the lens had “Nikon” or “Zeiss” badging, I would expect it to sell for $1200. Super wide lenses, by their nature, are more difficult to focus because they have extreme depth-of-field.� They challenge auto exposure metering because they include an extremely wide field of view.� These are not the lens’ fault, they are the way super wide lenses operate.� If you are not familiar with such lenses you’ll need to learn how to use them. 5
