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

[Multi-Coating] 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.

[T3] I purchased the IRIX 15mm, 45mm, and 150mm as a set. The image quality is sharp and excellent, the focus and t-stop rings work smoothly and quietly, and the build quality is first class and aesthetically beautiful. I particularly like the water sealing most other brand lenses in this price range do not have. Focus breathing varies between the lenses but minimally and I'm quite happy with them. As other reviewers have mentioned, the curved lens cap is the only disadvantage, preventing positioning any lens face down on a surface with the lens cap on, but that's a minor issue against the superb overall package these lenses provide.

[86 mm] What this LENS CAN DO IN Macro is MINDBLOWING!

[150mm] I shoot surgical/medical and thus needed that reach (compared to the Rokinon 100mm macro I was using before) in order to remain non-invasive to a health care professional's space. I also wanted a cine version of a macro so this was perfect and really there is no other option other than another 100mm macro cine lens. 
The images coming from my Fuji X-T3 with this lens are fantastic (rigged as shown using an EF to X-mount adapter). Feels like a solid lens. Not a fan of the magnetic hood but I use a matte box so no biggie. Lens cap and mount cover do suck, they feel like they could break from a drop. Focus ring is smooth but the iris ring is much looser in comparison, I wish they had the same tension.

[86 mm] Switching to the IRIX 150mm T3.0 Macro 1:1 Cine Lens from the Canon 100mm macro photo lens significantly enhanced my macro videography capabilities. The added 50mm focal length allows for closer, more detailed shots and a comfortable working distance, ideal for intricate scenes. This lens incorporates cinema-grade features, including a T3.0 aperture for superb performance in various lighting conditions, and precise control over focus and aperture, elevating the cinematic quality of your footage.

The lens's build is both durable and weather-sealed, ready for any shooting environment. Its sharpness is a standout feature, delivering crystal-clear images that showcase the finest details of your subject. This sharpness, alongside the extended focal length and cinema functionality, makes the IRIX 150mm a significant upgrade for filmmakers seeking to advance their macro cinematography. It's a powerful tool that combines creativity, control, and quality, making it an excellent choice for anyone looking to step up their macro video production.

[Multi-Coating] 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!

[Multi-Coating] 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.

[43.3 mm] Super simple & light durable with the leather tab

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