Irix 150mm f/2.8 is a modern and versatile macro telephoto lens designed for full-frame high-resolution DSLR cameras.
With its focal length of 150mm and 1:1 scale of reproduction, these are the basic features of the new product that allows comfort working with small objects. Thanks to the possibility of being able to move away from the photographed object, this makes the operation more convenient than using lenses with a shorter focal length. No shadows are cast on the object and it is also possible to use lamps dedicated to this type of photography.
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.
