Venus Laowa 100mm f/2.8 2x Ultra Macro APO Lens for Canon RF. Followed by the success of the Laowa 60mm f/2.8 2:1 Macro, the 1000° macro in f/2.8 2:1 is the second member of the Laowa 2:1 macro line. It features an apochromatic (APO) feature that chromatic aberration both in focus and out of focus is invisible. This 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 on the market, but its wider magnification range allows macro photographers to capture subjects of any size. This 100mm f/2.8 lens can also focus at infinity and serve as a portrait lens with exceptional optical quality. 2:1 Magnification. Laowa 100mm f/2.8 2:1 Ultra-Macro is the second 2:1 macro lens (The first is the 60mm f/2.8 ). The 100mm is one of the most common focal lengths for macro photography use. All 100mm macro lenses on the market can only reproduce 1:1 magnification (actual size) images. 2x magnification allows more detail to be seen through the lens. Photographers can now take advantage of the wider magnification range to capture bugs of different sizes. Apochromat APO Design (Invisible CA). The Laowa 100mm f/2.8 has an Apochromat (APO) design where chromatic aberration (CA) in both à In-focus and out-of-focus areas (LCA) are controlled to a minimum. CA has long been one of the most annoying aberrations for macro photography and now you can forget about it and focus more on taking a great photo.
