IRIX 150mm f/2.8 Dragonfly Macro Lens for Pentax K

Modern and versatile macro telephoto lens designed for full-frame high-resolution DSLR cameras. Its large 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 advertising and portrait photography, and the convenience of hand-held photography. The unique feature of the Irix 150mm f/2.8 lens is the 1:1 Macro reproduction ratio already available at a focusing distance of 0,345m. The lens is equipped with an aperture mechanism consisting of 11 aperture blades with a rounded shape which provides a pleasant blur of background and points of light. High precision of focusing across the entire range is ensured by a wide, rubber-coated focus ring with a rotational angle of 270 Degree. An additional Focus Lock ring ensures that the focus position remains fixed when needed. 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 ergonomics of the Firefly and the durable magnesium housing used in the Blackstone.
