Irix 150mm f/2.8 is a modern and versatile macro telephoto lens designed for full-frame high-resolution DSLR cameras. Its fast aperture of f/2.8 facilitates shorter exposure times, while its moderately long focal length of 150mm provides an excellent compromise between the narrow viewing angle desired in macro, advertising and portrait photography, and the convenience of hand-held photography. The lens is equipped with an aperture mechanism consisting of 11 aperture blades with a rounded shape which provides a pleasant blur of background or points of lightand helps to maintain exellent sharpness even after stopping down the aperture.
The Irix 150mm f/2.8 Macro 1:1 is the first lens available in the new Dragonfly series, which combines the lightness and perfect ergonomic of the Firefly and the durable magnesium housing used in the Blackstone.
