The gateway to the world of macro photography
Whether you’re a professional photographer looking for a lens for your next shoot, or an amateur looking to expand your focal range. The Irix 150mm f / 2.8 Macro 1:1 lens is a Macro lens created for your full frame (35 mm) camera, and is available in Nikon F, Canon EF, and Pentax K mounts. The lens allows you to take macro photos with a 1:1 magnification ratio. When you use a camera with an APS-C sensor, due to the crop factor, the magnification ratio will increase to 1,5:1.

Optics that guarantee sharp photos
Creativity, your ideas, and the effort you put into each photo would be nothing without the right lens. Thanks to many years of experience in designing optics, the Irix 150mm f/2.8 Macro 1:1 was meticulously engineered for incredible sharpness. The optical design has been made to produce an extremely sharp image from f/2.8. The use of 11 rounded aperture blades results not only in extremely smooth and soft bokeh, but also in minimizing the diffraction phenomenon (decrease in resolution associated with stopping down the aperture). With further stopping down, the image sharpness further improves, which is crucial in macro photography, because we are often forced to use small aperture values to obtain a sufficiently large depth of field.

A Build You Can Trust
It doesn’t matter if your traversing the hot sands of the Sachara or covering the vast expanse of Antarctica – this lens will endure any challenge.
The sealing system has been designed to protect the inside of the lens from moisture, dust, and sand. The lens is equipped with an internal focusing system, meaning it does not change its physical size during focusing. The whole body remains solid and study, and ready to operate in all conditions.

Ready for Any Conditions
Dragonfly is a combination of reinforced metal and composite elements. This combination has resulted in an extremely durable, compact structure, which thanks to internal focusing and multiple seals, remains resistant to adverse weather conditions.
At Irix, we believe that the lens is not just a tool in the hands of a photographer. The overall impression of the photo creation process is important to us. A lens has to be fun and easy to use! That is why the ergonomics and design of our products are so important to us.

Intelligent Lens Design
The Irix 150mm f/2.8 Macro 1:1 has a module that allows you to control the lens iris directly from the camera, thanks to which popular semi-automatic modes (PASM), and data recording in EXIF format are available.
The use of electronics also enables the lens to be equipped with a focus confirmation system – the camera will confirm the proper focus distance (either in the form of an icon in the viewfinder or sound), every time you set the focus correctly – it’s really easy!

  • Focus Lock – allows you to lock the focusing ring in a specific position, which is extremely beneficial when you want to be sure you set the correct magnification ratio, e.g. 1 : 1 while shooting.
  • Tripod clamp with foot (Arca Swiss standard) – macro photography requires extraordinary precision. We have good news for all photographers using a tripod: thanks to the tripod clamp, you can safely and securely attach your camera to the lens. Thanks to this solution, the center of gravity of the camera lens remains neutral, and the vibrations associated with focusing and operating the camera are minimized.
  • Focus ring – when shooting small elements, depth of field usually covers only a few millimeters or less, so it is important that sharpening is precise. The rotation angle of the focus ring on the Irix 150mm f/2.8 Macro 1:1 is as much as 270 degrees, guaranteeing extremely smooth and precise sharpening.
  • Focus ring ergonomics – after tireless testing, we have developed a material characterized by its high mechanical strength and resistance to adverse conditions. Special texturing allows for reliable and precise focusing, and dedicated embossing allows you to feel the position of the ring, making sharpening even easier.
