[L-Mount] Great lens, love the fact that it is weather sealed and the length of the lens doesn't change when focusing as all that is internal to the housing, IQ is extremely sharp and Bokeh is lovely!

[86 mm] My first adventure into macro photography. I really love the lens.
Here are some of my shots for my first time out in macro photography with the IRIX 150 mm macro lens.

[T22] I had been wanting to get this lens for a long time. I decided to reward myself and go ahead and order it. This is my first IRIX lens. The packaging from IRIX is fantastic. It made it feel like my lens was gift wrapped. I have taken it out 2 times already and love how the images turn out. I can't wait to see how the rest of my spring time photos turn out!

[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.

[L-Mount] The images are great and the focusing is wonderful - very precise.

[Full Frame] No f/stop iris adjustments possible with the original Pocket 6K. Iris control works fine with the Pocket 6K Pro.

[43.3 mm] I am new to photography, and I am not very good at it. However, I am interested with a niche related subject: astrophotography. With the equipment I have I can do both widefield and very narrow shots of the night sky, and I wanted something in between that I could also use on a day-to-day basis.
This was the winner from all my options. Opening the box, the build and materials quality is above my expectations. As far as macros go, I still have lots to learn. The main reason I bought this lens for is astrophotography, and doing this it really shines.
Shooting wide open the distortions are minimal, but stopping down to f/4 there is no noticeable fringing or coma, and the vignetting is manageable.
Manual focus is not something that bothers me, but the extremely shallow depth of field did surprise me, so it took me some time to get used to it.
All-in-all, for my experience level and the applications I use this lens in, it really provides more than I know what to do with.

[9] The IRIX 150mm f/2.8 Macro is well built, comfortable in hand, and delivers superb image quality. The manual focus range and resistance are perfect; allowing for very accurate focus adjustment. The weight of the lens is comfortable in hand. Overall a fantastic buy!

[86 mm] This lens is very nice. Photos are sharp. Colors are great. The 150 gives you some extra space between camera and subject. Yes, it's manual focus, but who uses autofocus during macro shots? I've used this for portrait shots too and it worked great. The 150 compresses the background and the 2.8 helps achieve a nice, blurry out-of-focus. Although some have stated that the throw on the focus wasn't suitable for portraiture work, I did not have any difficulties. This is a beautiful, well manufactured piece of glass.

[T2.6] The 150mm allows 1:1(or 2:1) with the TC, to be pretty far away from bugs. The Sharpness is terrific. Used with the manual helps in a mirrorless camera, its easy to get a sharp image in manual.
