After extensive research and development, Adorama presents the Fe 70-200mm F2.8 Gm Oss Ii G Lens, bundled with Hoya 77mm Uv and Cpl Filters. This lens is a testament to Sony's commitment to delivering unparalleled image quality, with a design that incorporates two aspherical elements and one Xa (extreme aspherical) element. These elements ensure high-resolution images across the entire zoom range and at all focusing distances. The lens also features two Ed (extra-low dispersion) glass elements, two Super Ed glass elements, and one Ed aspherical element. These elements work together to minimize chromatic aberration, while Sony's Nano Ar (anti-reflective) Coating Ii effectively reduces flare and ghosting. This lens is compatible with high-performance 1.4x and 2x teleconverters (sold separately) for additional reach.The Fe 70-200mm F2.8 Gm Oss Ii G Lens is designed to produce exquisite G Master bokeh, achieved through advanced optical design, an F2.8 aperture, and a new 11-blade circular aperture unit. The Xa element, manufactured to 0.01-micron surface precision, suppresses onion ring bokeh, while the new aperture unit helps to deliver natural circular bokeh. This lens also offers fast, precise autofocus, thanks to four of Sony's original Xd (Extreme Dynamic) Linear Motors. These motors deliver high thrust efficiency, boosting Af speed by up to 4x compared to the previous model. This results in fast, precise continuous autofocus and tracking for both stills and movies. Designed with movie magic in mind, this lens incorporates the latest lens technology to reduce focus breathing, focus shift when zooming, and axis shift when zooming. The Xd Linear Motors and a new aperture drive unit contribute to quiet operation, making this lens ideal for movie shooting. The Fe 70-200mm F2.8 Gm Oss Ii G Lens is the lightest in its class, offering outstanding optical quality and autofocus in a 70-200mm F2.8 zoom lens that weighs just 2.3 lb. (1045 grams). This is approximately 29% lighter than the previous model, thanks to the Xd Linear Motors and magnesium alloy barrel components. The lens also features professional control and reliability, with features such as Full-time Dmf (Direct Manual Focus), Linear Response Mf, and a focus-range limiter. An aperture ring with switchable clicks and an iris lock provides extra exposure control. Mode 1, 2, and 3 optical image stabilization ensure sharp images in different shooting conditions, and a dust and moisture-resistant design plus fluorine-coated front element maximize reliability in tough environments. In summary, the Fe 70-200mm F2.8 Gm Oss Ii G Lens, bundled with Hoya 77mm Uv and Cpl Filters, is a versatile, high-quality lens that delivers exceptional image quality, professional control, and reliability. It's the perfect addition to any photographer or videographer's gear collection..
