With LEICA DG MACRO-ELMARIT 45 mm / F2.8 ASPH. / MEGA O.I.S. phenomenal image quality is achieved with minimal distortions and chromatic aberrations as well as flare and ghosting that lives up to the strict Leica standard and exceeds all expectations. The lens system includes both an aspherical lens and an ED lens with its 14 lenses divided into 10 groups, which makes the camera incredibly compact and takes advantage of the Micro Four Thirds standard while minimizing distortion and chromatic errors.Panasonic's MEGA O.I.S. (Optical Image Stabilization) suppresses the blur that often occurs as a result of hand shake, making it easier to take sharp photos with focus and macro or in low-light locations without the use of a tripod. A direct-drive linear motor drive is integrated for 3-group focusing, providing great resolution and contrast without changing the overall length from full zoom to infinity. The integration of the stepped motor makes it easier and quieter to focus, both when taking pictures and recording movies. The closest focus distance can be quickly changed to 15 cm or 50 cm using the button on the lens, depending on the shooting situation. When the lens is mounted on the LUMIX G Micro System camera, it allows you to use the advanced AF function, including e.g. face recognition, which makes taking pictures more practical and fun. With the seven blades, the aperture gets a round shape, which gives a nice effect when zooming out at larger aperture settings. LEICA DG MACRO-ELMARIT 45 mm / F2.8 ASPH. / MEGA O.I.S. the lens is also equipped with a robust metal base and uses multi-coated lens elements that minimize flare and ghosting to further improve its optical properties.
