Laowa 90mm f/2.8 2x Ultra Macro APO for Micro Four Thirds

The Laowa 90mm f/2.8 2x Ultra Macro APO for Micro Four Thirds is presented as the world's first 90 mm f/2.8 2x macro lens for the system. Where standard macro lenses stop at 1:1, it reaches 2:1 magnification, which with the 2x crop factor of the Micro Four Thirds sensor corresponds to 4x on full frame: microscopic textures and details become visible, a real advantage for nature and scientific photography. It still focuses to infinity, and with its 180 mm equivalent focal length it also works as a compressed portrait lens.

The apochromatic optical formula with 13 elements in 10 groups, including 3 ED elements, reduces longitudinal and lateral chromatic aberration close to zero, so high-contrast edges stay clean even wide open at f/2.8, and sharpness peaks at f/8. The 9-blade aperture gives soft, creamy bokeh.

This Micro Four Thirds version has electronic contacts: the aperture is set from the camera body and EXIF data are recorded, with better support for image stabilisation. Focusing is manual, and internal focusing keeps the length constant, so you can work at the 20.5 cm minimum focusing distance without the barrel extending towards sensitive subjects or lighting setups. With about 540 g and 115 mm in length it stays compact for handheld field work.
