Venus Laowa 100mm f/2.8 2X Ultra Macro APO Lens for Nikon F/AI Mount Camera

100mm f/2.8 2:1 Macro is the 2nd member of Laowa 2:1 macro line-up. It features an apochromatic (APO) characteristic that chromatic aberration at both ‘in-focus’ & ‘out-of-focus’ is both invisible. This new 100mm lens can cover full frame sensor size and focus from 2:1 magnification to infinity. The lens has a similar physical size to other 100mm Macro lenses in the market but its wider magnification range allows macro photographers to capture subjects at any sizes. This 100mm f/2.8 lens can also focus to infinity and serve as a portrait lens with exceptional optics quality. Only Canon EF version is equipped with a CPU chip and motor for aperture control via the camera. All other mounts are manual and aperture is controlled by the aperture ring on the lens. The extended 2x magnification means more details can be seen through the lens. Photographers can now take advantage of the wider magnification range to capture bugs at different sizes. Laowa 100mm f/2.8 2:1 Ultra Macro APO is not only a exceptionally macro lens. It can also focus to infinity and is a very decent telephoto portrait lens.
