Leica APO-Vario-Elmarit-SL 90-280mm f/2.8-4 Lens (L-Mount) This high-performance telephoto zoom is designed for L-Mount mirrorless cameras, covering a versatile 90-280mm focal length range. It is suitable for full-frame cameras and provides a 135-420mm equivalent range when used on APS-C models. Key Optical and Image QualityApochromatic Design (APO): The lens features an apochromatic design, utilizing seven anomalous partial dispersion elements within its complex 23-element, 17-group construction. This engineering virtually eliminates chromatic aberrations (color fringing) throughout the entire zoom range, ensuring exceptional color accuracy and clarity. Bright Aperture: The f/2.8-4 maximum aperture is ideal for working in varying light conditions and provides excellent control over depth of field for selective focus techniques. Consistent Performance: The lens maintains consistently high clarity and sharpness across all focal lengths, from the minimum focus distance to infinity. Focusing and StabilizationFast, Internal Autofocus: The lens uses a Dual Internal Focusing mechanism, where two dedicated focusing elements are driven by linear stepping motors. This system delivers rapid, silent, and highly precise autofocus performance. Constant Length: Both focusing and zooming are internal, meaning the physical length of the lens does not change, and the front 82mm filter ring does not rotate, simplifying the use of polarizing or graduated filters. Image Stabilization (OIS): An optical image stabilization system is built-in, compensating for up to 3.5 stops of camera shake to enable sharper handheld shooting, especially at the long end of the zoom. Build and HandlingWeather-Sealed Construction: The lens features a fully dust and water-sealed design for robust protection when shooting in challenging weather conditions. AquaDura Coating: The front and rear optical surfaces are treated with Leica’s AquaDura hydrophobic coating to repel water and resist smudging. Tripod Collar: Includes a removable, rotating tripod collar for increased stability when mounted. The collar features firm detents every 90 degrees, allowing for seamless switching between horizontal and vertical shooting orientations. Close Focus: Minimum focus distance is 2 feet (0.6m) at 90mm and 4.6 feet (1.4m) at 280mm. Includes the hood.
