Overview

The IRIX 150mm f/2.8 Macro 1:1 offers excellent center sharpness and good edge performance, with minimal distortion, chromatic aberration, and coma. Its 11-blade aperture produces smooth bokeh. Build quality is solid and weather-sealed, though it lacks autofocus and stabilization, making handheld use challenging. Weaknesses include flare susceptibility and astigmatism. It suits macro and studio photographers on a budget who prefer manual focus, offering a longer working distance than 100mm macros.
