Related Questions and Answers

Q: 1. Is this lens suitable for still photography as well as for video?

A: While the IRIX 150mm T3.0 Macro 1:1 Lens is designed for Cinema use it would also be perfect for still photography. Keep in mind it is a manual lens with no autofocus or stabilization.

Q: 2. Does this lens work on the FTZ adapter for Nikon Z cameras?

A: The IRIX 11mm f/4 Firefly Lens for Nikon F is a manual focus and exposure lens that is compatible with Nikon Z cameras with the FTZ adapter.

Q: 3. 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: 4. What mm size UV protective filter fits this Irix 11mm Blackstone Lens?

A: Due the shape of the front element on the IRIX 11mm f/4 Blackstone Lens for Canon EF, it doesn't accept screw in UV protective filters.

Q: 5. 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: 6. How does this work for a telephoto lens?

A: Yes, IRIX 150mm T3.0 Macro 1:1 Cine Lens would also work for telephoto use.

Q: 7. Does this support the manual focus confirmation with recent DSLRs?

A: Yes, it does.

Q: 8. 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: 9. Can we get ND filter for this lense ?

A: Yes, But a adapters are needed. Please look into the following item. Cokin Universal X-Pro Series Filter Holder Adapter Ring https://bhpho.to/37clouY Cokin X-Pro Series Filter Holder https://bhpho.to/3C9fTLZ

Q: 10. I'm assuming this is a strictly manual focusing lens - correct?

A: That is correct. This is a Manual Lens only.

[43.3 mm] The IRIX 15mm T2.6 Cine is my go-to for shooting in tight spaces, like car interiors. Its wide-angle capability allows for capturing extensive detail in confined areas, making it ideal for automotive shoots. The T2.6 aperture ensures excellent performance in low-light conditions, crucial for maintaining quality inside vehicles. Balancing impressively on gimbal rigs, it proves to be a versatile workhorse, capable of handling dynamic shots with stability and clarity. Its durable build adds to its reliability, making it a trustworthy choice for demanding environments. In short, the IRIX 15mm T2.6 combines wide-angle versatility, low-light proficiency, and rugged durability, standing out as an essential lens for producing high-quality, creative shots in limited spaces. It’s a valuable asset for any video project requiring sharp and expansive visuals in compact settings. 5

[9, Rounded] But unfortunately I've heard of some of them coming apart internally. So... hopefully mine lasts, because it certainly makes gorgeous images and is a pleasure to rig and use on set. I'd compare it and cut it with my Zeiss Milvus lenses, no joke. 5

[Canon EF] I use this coupled with my BMPCC 6K Pro. Like most cinema lenses, this is massive. Be prepared for a workout if you are going handheld. Gearing is very smooth, although a bit stiff if not using a focus wheel. I own all of the cinema lenses and two of the three have decent magnetic hoods, while one does not appear to be as strong. This doesn't affect me as I utilize a matte box. Like most have stated, the lense cover is complete garbage. Pops off for no apparent reason. 5

[Full Frame] Quality optics and build. Light for a cine prime, and easy to use. Works well on our RED Komodo. Smooth focus and aperture rings. The magnetic filter system is quick and easy. Also have the IRIX 30mm Cine T1.5. We tested both lenses and found no issues. The blue infinity marking really is at infinity and the other markings appear to be accurate as well. The only complaint is the rounded lens cap that comes with the lens. We were told that IRIX is going to offer the better, flat cap they provide with their 30mm T1.5 for this and older models. Kudos to them for that improvement. Overall, this is a surprisingly good cine prime series considering the low price. 5

[43.3 mm] 15mm on S35 is great. I thought this would be too wide and wished IRIX made a 25 or 35 but actually to compliment the existing 45 they sell this 15 is a good match feeling wide but not super distorted wide. Magnetic hoods are cool, but not so much if you are filming metalworking - all the dust just sits on those magnets. Minor quibble but the lens is great! 5

Michael	03/05/2024
[T4.3] This is a really good lens. Great build quality, excellent performance, low distortion, little breathing. I'm going to get a set of these Irix Lenses, pretty impressed! 5

[11mm] This lens works as advertised. It has a ton of professional features and a lower price range. 5

Robert	30/11/-0001
[Canon EF] Feels solid, but isn't overly heavy. Image quality is great and distortion is reasonable. I shoot it both full frame and S35 and it handles both well. As others have said, it's true that the lens cap is wonky. Apparently they have a fixed one that you can order separately and hopefully that's what will ship with new copies of the lens. I use it via an adapter and did have a little trouble finding a friendly one. Fotodiox PL-EF did NOT work. I eventually went with some no-names on eBay that did. 5

Manuel	30/11/-0001
[Full Frame] It never stoped to amaze me the kind of build this lens has. Nice big and a little on the heavy size. I will compromise well build for fragility, I may also add this has a very nice glass. Overall very satisfied with the lens. 5
