A new era of standard zoom performance

No-compromise design and technology result in a constant F2.8 zoom lens that can fully utilise the potential of current and future high-resolution camera bodies. This peerless standard zoom covers a 24 mm to 70 mm focal length range, and is an ideal choice when ultimate image quality is required for portraits, scenery, snapshots and more.

Extraordinary resolution and bokeh

An XA (extreme aspherical) lens element with superlative surface precision not only contributes to stunning corner-to-corner resolution and detail throughout the zoom range, but also plays a vital role in achieving smooth, soft bokeh that can be a powerful expressive tool in a wide range of photographic situations.

 

Natural rendering and colour

One ED (Extra-low-Dispersion) and one Super ED glass element in an optical path that has been designed to the highest standards help to achieve lifelike, natural imagery without unnatural colouration by keeping axial and lateral chromatic aberration in check while maximising subjective resolution for breathtaking texture and detail.

Bright, fast F2.8 at any focal length

A constant F2.8 maximum aperture makes it easy to keep exposure settings constant throughout the zoom range to maintain low-light capability or action-stopping shutter speeds. Consistently spectacular image quality is ensured at any aperture or focal length

Precise focus at blazing speed

In addition to positioning large-aperture lenses with extremely high precision for spot-on focusing, the Direct Drive SSM (DDSSM) system minimises 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.

9-blade aperture enhances bokeh beauty

The remarkable beauty of this lens’s bokeh is further enhanced by a 9-blade circular aperture design that contributes not only to smoothness, but to natural highlights as well.

Outstanding clarity and contrast

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. (1. Nano AR Coating / 2. Glass / 3. Transmitted light)

Versatile fingertip focus control

The ability to respond quickly to rapidly changing shooting situations can mean the difference between getting the shot or not. A manual/auto focus mode switch and focus hold button are positioned for easy access, providing versatile, professional control for a wide range of subjects and environments.

Zoom lock improves portability

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.

Hood lock and release

A hood lock mechanism prevents accidental hood detachment when moving from location to location, while a hood release button makes it easy to remove and replace the hood whenever necessary.

High reliability in harsh conditions

Careful dust and moisture sealing measures have been implemented to ensure maximum protection and reliability in challenging environments. Shoot with confidence in light rain or windy conditions.
