[Full Frame] 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.

[T32] 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.

[11] Beautiful image and solid construction, looks great on set of a production

[1:1] 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] And much lighter than a Canon 100mm macro. The extra 50mm is ideal for macro work. The lack of stabilization is a non-issue as macro work always requires a tripod. Well-constructed and seemingly durable at a very good price. Recommended.

[T32] 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] For the price, this lens rocks! If it were three times the price it would still rock! There’s plenty of YouTube video reviews of technical specs, but creatively, I found that this lens gave me a cinematic (subjective, I know), shallow depth of field with crisp focus. Definitely need a focus-puller and stability, but even without the latter, you can pull off some interesting shots. This will be a holy grail lens for product filmmakers, but it’s extremely capable of pulling off some narrative shots.

[1:1] Okay so I took my new toy to Costa Rica for two weeks just after receiving it, thinking that I might use it 50% of the time at best. Well as it turns out, I took roughly 90% of my shots with that lens mounted on my Pentax K70 and the performance was stellar. Smooth focus ring, fast enough for the dark rainforest, sharp as a tack and buttery smooth bokeh. A wide angle IRIX lens is next.

[Full Frame] I use the IRIX 150mm f/2.8 Macro lens on a Nikon D850. The lens is solidly-built, but not very heavy. Since I shoot my macro either on a tripod, a focusing rail or with flash, the lack of image stabilization is never a factor. Additionally, macro is best done with manual focus, so the lack of auto focus is not an issue. The focusing ring is large, smooth and very easy to use at macro/close-up distances. Toward infinity, the range of movement is more limited and it takes some patience to get sharp focus. I have used this lens also for tracked astrophotography with good results, but is best stopped down to f/5 because of some coma at the edges of the full frame. For regular use this lens appears sharpest at f/11, then f/16, then f/4. I have noticed no chromatic aberration. The bokeh is excellent. The tripod collar is handy and works well. So far, I have found little need for the focus lock function and have noticed no evidence of a focus shift with the lens pointed downward when focus stacking. Metering and aperture control in camera works fine. As for the most important aspect, how do the pictures look? The images have been very sharp with good detail, contrast and color all across the frame. I am very satisfied with this lens as well as the excellent and prompt service by B&H. If I were to compare it with another one of my macro lenses I would sat that the images are sharper with this IRIX lens than with my older Nikon 200mm macro lens. This lens is designed for macro as close as 1:1 and it certainly performs as promised.

[Canon RF] I couldn't imagine a lens being this good for macro photography. I'm really happy with it. See the results with the photos I uploaded. It's really fun to use. It's built very well and includes a nice arca type tripod collar and foot.
