[9] Right out of the box it is really a heavy duty professional lens. The focus is a bit stiff, but might loosen up over use. Happy with it and looking forward to shooting with it over time.

[43.3 mm] 8K sharpness, weatherproof, low focus breathing, solid metal build quality, 180 degree focus throw. The list of features go on and on. For the price I have never found a lens like this. I compared for months Sigma Art series, SLR Magic’s, Zeiss Milvus. Personally this lens should sit next to higher price brackets like Sigma Cine, New XEENs, Zeiss CP2’s. Having this lens for a week I can say this lens lives up to every feature. Shooting on my Pocket 6K this thing makes it feel like I have a whole new camera or at least like I’m finally taking full advantage of my sensor. Can’t recommend this lens enough. I plan on buying the brand new 15mm Cine and the 150mm Cine macro all 3 will be the price of a single average priced Cine lens!

[Canon RF] I've been renting cine lenses for years for some of our bigger projects but never pulled the trigger on getting one. I mean, I have the Sigma 18-35 Art (photo) lens and I just can't justify spending 4K on the cine version. But this lens comes at a great price (paid $1,200) which in early 2020, happens to be cheaper than the Xeen primes. Not to mention Canon, Sigma, Zeiss CPs and the rest. -- I've shot a few test shots and the 45 looks very sharp and smooth with no noticeable CA. Focus throw is 180° and the overall feel is solid! - Can't wait for Irix to come out with a couple of more primes.

[Full Frame] 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.

[45mm] Glad Irix finally added something between the 45mm and 150mm. If you're already rocking a set of these primes, the 65mm is a must! Used them for my b-cam side profile angle last week and loved the look of this lens.

[Full Frame] 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.

[T1.5] 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!

[Imperial] 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.

[T1.5] I was a little bit skeptical about buying this lens at first considering that I've never heard of Irix before. However, don't let that stop you. This lens is extremely sharp, even at wide-open!!! The footage you can get with this lens at T1.5 is crazy! Not to mention that this lens doesn't have any noticeable color fringing, and is constructed out of a solid metal exterior, and doesn't flare at all when in direct sunlight. If you're looking for a budget cinema lens that punches a lot higher than its price, I can't recommend this lens enough.

[9] I've had many lenses over the years, I often researched what others liked or believed what YouTube videos said, but this time I decided to make a choice and decide for myself if this lens was for me. From the moment I opened the box of the Irix 30mm T1.5 RF version, I knew I had made the right choice. The weight of the lens, the position of the gears and the out of the box colors paired with my Red Komodo left me speechless. The lens handles light just the way I've been looking for, and the look the lens adds to the already amazing image quality and color accuracy of R3D made this lens for me a winner. I highly recommend this lens, especially if you want a true cinema lens and desire quality and performance at an outstanding price point. Will definitely purchase more from this brand in the future.
