From the Manufacturer
The world's first Leica Micro Four Thirds lens, the Leica DG Macro-Elmarit 45mm/F2.8 ASPH/MEGA O.I.S., features exceptional image quality in a compact size.
The Leica DG Macro-Elmarit 45mm/F2.8 ASPH/MEGA O.I.S. (equivalent to 90mm on a 35mm film camera), features outstanding image quality that meets the renowned Leica standard. The new Leica lens uses both an aspherical lens and an ED lens comprised of fourteen lenses arranged in ten groups. This lens takes advantage of the Micro Four Thirds specifications to achieve a dramatic size decrease, while also minimizing distortion and glare. Panasonic's Mega Optical Image Stabilizer (O.I.S.) suppresses the blurring that is commonly caused by hand-shake, making it easy to shoot sharply-focused macro shots even in dimly-lit places without the need for a tripod.
The Leica DG Macro-Elmarit 45mm/F2.8 ASPH/MEGA O.I.S. lens incorporates an inner focus motor system that makes action smooth and silent when capturing still and video content. By flipping a switch on the lens barrel, the minimum focus distance can instantly be changed to 150mm or 500mm (approximately 5.9 inches or 19.7 inches respectively). This lens excels when taking portraits, mid-range snapshots and landscapes, in addition to macro shots.
When mounted on Lumix G Micro System Cameras, the Leica DG Macro-Elmarit 45mm/F2.8 ASPH/MEGA O.I.S. lens allows for use of the advanced contrast Auto Focus (AF) system, which includes Panasonic's Face Recognition functions. It's comprised of seven blades, which produce an attractive and smooth background blur effect when shooting at larger aperture settings. These lenses also feature a highly-reliable metal mount, and use multi-coated lens elements to minimize glare and further enhance optical performance.
