Description
This is a detailed description of the Sony FE 24-70mm f/2.8 GM II lens, which is a high-end standard zoom lens designed for full-frame cameras. Here are the key features and benefits:
**Optical Performance**
* Refined optics provide even greater resolution, clarity, and bokeh quality
* Bright f/2.8 constant aperture for capturing images in dim lighting conditions and with a shallow depth of field
* Two ED (extra-low dispersion) and two Super ED elements to minimize chromatic aberrations and color fringing
* Five aspherical elements, including two extreme aspherical elements (XA), to minimize spherical aberrations, distortion, and “onion ring” bokeh
* Nano AR Coating II to control flare and ghosting
**Focusing**
* Four XD (extreme dynamic) Linear Motors for faster, quieter, and more precise autofocus performance
* Floating focus mechanism for improved image quality throughout the focusing range
* Internal focusing design for snappier, more responsive focusing performance
**Control and Video Capabilities**
* Focus breathing, focus shift, and axial shift during zooming minimized to prevent unwanted movements and angle of view variations
* Supports Breathing Compensation function in select cine-line and Alpha cameras
* XD Linear Motors quiet enough for AF during video recording
* Linear Response MF provides natural, intuitive manual focus control
**Design**
* Compact, lightweight, and robust design
* Approximately 22% lighter and 18% smaller than its predecessor
* Weather-sealed, durable design with rubber gaskets at each seam and a rubber ring sealing the lens mount
* Front lens element with fluorine coating that repels water, oil, and other contaminants
**Other Features**
* Manual aperture ring with de-clickable option for smooth and silent iris pulls or locked in the ‘A’ position for camera-based aperture switching
* Two programmable focus hold buttons and a focus mode switch for intuitive focus control
* Zoom smoothness switch for changing between Smooth and Tight zoom ring torque
Overall, this lens is designed to provide excellent optical performance, fast and accurate autofocus, and robust build quality, making it a great choice for professional photographers who need a versatile standard zoom lens.
