The Sony SEL2470GM lens features constant F2.8 24-70mm zoom for E-Mount (and E-Mount APS-C) cameras. Part of Sony's G Master lens series, it's a standard zoom that's not so "standard" with an unprecedented union of high resolution and creamy bokeh.
Constant F2.8. Keep exposure settings constant throughout the zoom range to maintain low-light capability or action-stopping shutter speeds with consistently spectacular image quality.

Nano AR Coating. Sony’s original Nano AR Coating suppresses spurious reflections that can cause flare and ghosting, particularly in backlit situations. The result is consistently high contrast and clarity with deep blacks in the widest possible range of photographic situations.
Direct Drive SSM In addition to positioning large-aperture lenses with extremely high precision for spot-on focusing, the Direct Drive SSM (DDSSM) system minimizes spurious motion while an advanced control system and refined algorithms enhance AF operation speed. DDSSM is also smooth and quiet, making it advantageous for movies as well as stills.
Zoom Lock Zoom lenses can sometimes extend under their own weight during transportation, and that can be a nuisance while increasing the chance of accidental damage. A zoom lock switch provides a simple, sure way to lock the zoom mechanism for safe, convenient transportation.
