[45mm] 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.

[Full Frame] 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.

[Canon EF] 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] 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!

[Imperial] First impressions, this lens is well built the focus and aperture rings have a nice resistance. I am having so much fun with this lens, it has interesting characteristics. The lens so super crisp.

[43.3 mm] 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.

[Imperial] Having used IRIX lenses since initial launch of their Cinema Line, I would say the 65mm lens is a great addition to the line up. Having used it it already on a project with the RED Komodo and Canon Focal Reducer I would have to say the image it produces is great. I have not noticed any chromatic aberrations in the footage I have shot.

[45mm] 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.
