[86 mm] In over 40 years of industrial and feature film making, the Irix primes are my favorite series of prime lenses, favored over the big name lenses that cost 4-5x. They are fast, sharp, have very natural-looking out-of-focus highlights, and the sealing is a bonus for those like us, who shoot a lot of exteriors. Hopefully Irix will soon offer something in the 65mm-85mm range so we can relegate our current short telephoto to the B camera lens set.

[T22] I did a comparison between the Canon CNE 35mm and the IRIX 45mm and if you were not told you could not tell the difference. The sharpness, chromatic aberration, Lens flares, and bokeh looked really similar.

[3.305 lb] I purchased this lens for my sony FX9 and I shoot with the raw extension. I mostly use the 28/135 F4 sony cine zoom lens. I needed something a bit more wide with a fastest aperture. My dream came true. this lens is excellent, extremely sharp and delivered stunning results. I have tried also the sony 16/35 GM master f2.8.. . but sometimes a real cine lens is better when autofocus(es) has their limitations and when manual focus is required for creativity. highly recommended

[15mm] 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.

[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.

[T2.6] 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.

[Full Frame] I recently purchased the IRIX 45mm, 150mm, and this 15mm the color from all the lenses seem to match very well. This lens has very little distortion for being such a wide lens.

[9] 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.

[T2.6] 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.
