The popular ZEISS Vario-Sonnar T* 24–70 mm F2.8 zoom has been refined for even better performance. This lens is already widely regarded as being more like a prime lens than a zoom in terms of image quality, but the new edition further reduces ghosting for a notable improvement in clarity. Lens processing has also been revised for faster subject tracking, and it is dust and moisture resistant.
Prime lens-class resolution and contrast are achieved thanks to two aspherical elements and two ED (Extra-low Dispersion) glass elements in a precision ZEISS optical design.
A bright constant F2.8 maximum aperture throughout the zoom range means consistent exposure settings at any focal length plus improved low-light capability.
The SSM (Super Sonic wave Motor) drive system coupled with an internal focus mechanism achieves smooth, silent autofocus operation and fast response.
A focus mode switch and focus hold button on the barrel offer extra focusing versatility and control.
Legendary ZEISS quality manufactured and calibrated specifically for Sony imaging products. The ZEISS T coating contributes to exquisite rendering and contrast.
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
