What sets the Lumix G Leica Dg Vario-Summilux 10-25mm f/1.7 Aspherical Lens apart is its innovative design and high-quality performance, specifically crafted for Micro Four Thirds mount cameras. This professional-grade lens offers a consistent F1.7 aperture brightness across the entire 20-50mm zoom range (equivalent to 35mm camera), surpassing the stringent Leica standards. Designed not only for high-resolution photography but also for superior video recording, this lens caters to the needs of both professional photographers and videographers. It comprises 17 elements in 12 groups, including three aspherical lenses and four Ed (Extra-low Dispersion) lenses. These components work together to effectively suppress axial chromatic aberration and chromatic aberration of magnification, ensuring stunningly sharp and clear images.The aspherical lenses also correct spherical aberration and distortion, resulting in a high-resolution output.
