Sony SEL2470GM FE 24-70mm f/2.8 GM Lens

Sony FE 24-70mm F2.8 GM Standard Zoom Lens Featuring some of the most advanced lens technologies in the market today, the new FE 24-70mm F2.8 GM (model SEL2470GM) is the ultimate choice for those seeking the highest possible optical performance for portrait, travel and event photography or even simple everyday shooting. The new lens is built with three aspherical elements including a newly developed, extremely precise XA (extreme aspherical) element that reduces aberration and delivers the ultimate resolution throughout the entire zoom range and aperture range, as well as from corner to corner of all image files. Additionally, an ED (Extra-low-Dispersion) glass element and Super ED glass element keep chromatic aberration to a minimum while maximizing resolution and bokeh without any unnatural coloration. The lens features a 9-bladed aperture that maintains a near circular shape at all settings and is coated with Sony's original Nano AR coating to suppress reflections and ensure spectacular contrast and clarity. The new FE24-70mm F2.8 GM lens has a direct drive SSM (Super Sonic wave Motor) focusing system that works with incredible efficiency thanks to a new set of algorithms that position the lens elements quickly and accurately. The motor is smooth and quiet, making it an ideal choice for shooting both still images as well as movies. To maximize usability, the lens is dust and moisture resistant and features a compact, streamlined design that includes AF/MF switch as well as focus hold, zoom lock and hood release buttons. SpecificationsLens MountSony E-mountFormat35mm full frameCompatabilityE-mount 35mm Full Frame E-mount APS-C camerasFocal Length (mm)24-70mm35mm Equivalent Focal Length (APS-C)(mm)36-105mmLens Construction (Groups, Elements)13 groups, 18 elementsAspherical Lenses3 aspherical (1 XA)Extra-low Dispersion Glass2 (1 Super ED glass/ 1 ED glass)CoatingNano AR CoatingMaximum aperture (F)f/2.8Number of Aperture Blade9 circularCircular ApertureYesMinimum focus distance (m)0.38mMaximum Magnification Ratio (x)0.24xLens MotorsDirect Drive SSMFilter Diameter (mm)82mmHood TypePetal shape, bayonet typeDust and Water Resistant
