Additional information:

The Irix 150mm f/2.8 Macro 1:1 is a prime telephoto macro lens for full-frame SLRs and SLMs.

Developed for the Nikon F, Canon EF, and Pentax K mount, the lens allows photographers to shoot tiny subjects and objects from further away than when using macro lenses with a shorter focal length. This helps eliminate shadows and allow for different types of lighting.

The lens features an 11-blade rounded aperture for pleasing bokeh when shooting wide open and reduced diffraction when stopping down.

There’s weather-sealing at key points that allow the lens to be used in adverse weather conditions such as rain and snow.

The focus ring features a slightly protruding “rubber handle” to provide adjustments with a 270-degree rotation.

There’s also a Focus Lock feature that locks the ring in a specific position.

Other features and specs include a 12-element 9-group design, a 1:1 scale of reproduction, an internal focusing system (the lens doesn’t change size while focusing), a CPU and AE module for camera aperture control and semi-automatic modes (PASM), EXIF data recording, a deep lens hood, and a detachable Arca Swiss lens collar.
