High-Quality Macro. The Irix 150mm f/2.8 Macro 1:1 Dragonfly features a life-size 1:1 maximum magnification and a 1.1-foot minimum focusing distance to really let you get in close. Its bright, f/2.8 maximum aperture works well in a range of lighting conditions and gives you excellent depth-of-field control. Using an APS-C camera? This lens will give you 240mm equivalent focal length.

Advanced Optics. The Irix 150mm f/2.8 Dragonfly’s twelve-element/nine-group optical design controls distortions and aberrations while retaining sharpness and clarity at any focus distance. The Neutrino coating controls ghosting and flare for a color-neutral image.

Premium Build. The 15mm f/2.4’s durable aluminum and magnesium-alloy housing boasts an anti-scratch finish and high-visibility depth-of-field scales. Its weather-resistant construction includes internal seals to guard against dust and moisture, and an additional seal to protect the front element. The included tripod collar includes an Arca-type compatible foot for wide tripod-head compatibility.

Modern Manual Focus. This fully manual-focus lens features a positive focus lock mechanism to help prevent focus shifting, while a hard click stop indicates the infinity position on the focus ring for easy use when you’re working in low-visibility conditions. There’s a built-in electronic module (AE) that enables focus confirmation, aperture control, auto-exposure and semi-automatic modes (PASM), which also ensures all exposure parameters are saved in the EXIF data.
