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
