Irix 150mm f/2.8 MACRO 1:1 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 light and helps to maintain excellent sharpness even after stopping down the aperture.
Irix 150mm f/2.8 MACRO 1:1 lens will start shipping in December. The price of the lens is $595. Pre-orders are now open at B&H Photo. You can purchase Irix lenses are sold at Amazon US | Amazon UK | Amazon DE.
