The full force of Sony’s latest lens technology brings stunning G Master resolution and exquisite bokeh together in the world’s lightest2 Full Frame F2.8 constant aperture Standard Zoom lens. With significantly evolved AF performance, the FE 24-70mm F2.8 GM OSS II can deliver the full potential of today’s advanced still and movie cameras..Zoom system : Manual. Angle of View (35mm) : 84°-34°. Angle of View (APS-C) : 61°-23°. | Excellent contrast at high spatial frequencies means superb resolution even at F2.8. Two high-precision XA (extreme aspherical) elements, two ED (Extra-low dispersion) glass elements, two Super ED glass elements, and a floating focus mechanism control aberration, realize sharp, clear images at all zoom and aperture settings. | This lens is the smallest and lightest F2.8 24-70mm zoom in its class2. It weighs just 24.6 oz (695 g), over 20% less than the previous model. It is 16 mm shorter, and overall volume has been reduced by approximately 18%. Excellent mobility makes it a great choice for professional or enthusiast still or movie use in a wide range of situations. | Four of Sony’s original XD (extreme dynamic) Linear Motors, a floating focus mechanism, and advanced lens control achieve fast, precise and quiet AF with excellent tracking. Shoot at up to 30 frames per second3 or up to 4K 120p with a compatible camera body. A new aperture unit also contributes to high speed, enabling full AF tracking performance with the aperture stopped down4. | Advanced lens design reduces focus breathing, focus shift and axial shift when zooming. Image and angle of view shifts are minimized for smooth movie imagery. XD Linear Motors and a new aperture unit contribute to quiet, low-vibration operation. The breathing compensation function provided in compatible α series bodies is also supported5
