This is a very well built lens, very sharp, good bokeh, good cine features

This lens is truly a gem. Superb craftsmanship, sharpness and color rendition., it's a wide angle lens with very little distortion. Pulling focus is a breeze with this lens. With added accessories it has turned my BGH1 into a full-fledged cinema rig.

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.

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.

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.

The IRIX 150mm is an excellent choice for those looking to capture highly detailed, true-to-life close-ups. Its magnification ratio means you can get incredibly close to your subjects, rendering them in life-size on the screen, which is perfect for both professional and creative projects. The T3.0 aperture ensures that you have flexibility with light, working well in both bright outdoor settings and more controlled indoor environments. This lens is built to last, with a robust, weather-sealed construction that can handle a variety of shooting conditions without breaking a sweat. The focus and aperture adjustments are smooth and precise, which is crucial for making those critical, on-the-fly changes during a shoot. Image quality is where this lens truly shines, delivering sharp, clear visuals with beautiful background blur that helps your subject stand out. It's equipped with features like geared rings that are compatible with follow-focus systems, making it an excellent fit for professional video production. While it's a bit heavier and requires manual focus, the quality and versatility it offers make it a worthy addition to your kit. Overall, the IRIX is a solid investment for filmmakers and videographers seeking exceptional detail and build quality in their work.

I got the 15mm and the 45mm. There Great!!!

Excellent affordable cine lens that I?m using on a full frame beast of a camera! Sigma fp!!

The image shows a close up of a Lego set using the IRIX 150mm lens. In that picture you can see the small rigs in the gray plastic that is not visible by just looking at it.

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.

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.

Excellent for detail shots. It works as a telephoto lens but focus pull is way to fine beyond a couple of feet away from subject to really rack focus, so I would not recommend using this as a telephoto unless you can fix focus. No complaints as a macro lens though.

sharpest lens i?ve ever used! i?ll definitely be checking out some more of the cine line :)

I've been shooting with this lens on my RED Helium, but I also use it for stills with my A7III. The focus throw is smooth and long, and there is little breathing between short distances or between long distances (although, as expected, if you pull from a couple inches away to infinity, there is a transition where it breathes heavily). It feels well made and the images are very sharp.

The lens came very well packaged. The actual lens is very high quality. after using it for a short amount of time i can see that it is very well made and feels very nice to use. I got the MFT mount to u

I really enjoy this lens. The look of the image is sharp and feels amazing. The build is tanky. No regrets.

What more could you ask for in a lens. I was very skeptical at first as I work in film production and we rent lenses all the time. I wanted something that I could use for my red that could live on the camera for run and gun doc work. This lens has blown me away in the short two days I've used it. It is very sharp and has this unique look to that reminds me of having a pro mist filter on it. The build is heavy and strong and feels like a mini tank. I've gambled with lenses for 5 years and am very happy with this purchase. I will be buying more. Thanks Irix!!!!!!! You guys rule.

I needed a lightweight, cinema style macro lens for my motion control rig. This works perfectly. At the right price. Very happy

I love the lens. It is beautifully crafted and sturdy. The weight of the lens will take a bit of getting used to so I don't suggest using it without mentally preparing for the weight or having a stand if you don't want to hold it. There is no image stabilization but that is to be expected; however, the smooth focus and aperture are amazing. They allow for a really really precise image whether photo or video. This is my favorite lens.

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
