Optimised for close-up shooting, the Leica DG Macro-Elmarit 45mm f/2.8 ASPH. Mega OIS O.I.S. is a short-telephoto, 90mm equivalent prime for Micro Four Thirds mirrorless cameras. Designed to strict tolerances in collaboration with Leica, this lens's optical design makes use of aspherical and extra-low dispersion glass elements to reduce aberrations and distortion for notable sharpness, clarity, and colour accuracy. Multi-coated elements also contribute to a reduction in lens flare and a floating elements system helps to maintain consistent image quality throughout the focusing range.
