Alongside the Sony a7R III, the company also announced an FE 24-105mm F4 G OSS lens, adding a versatile zoom to a growing family of full frame Sony mirrorless glass - now totaling 23 lenses.

It uses a Direct Drive SSM motor, which should mean fast, silent subject acquisition, making it useful for photographers and videographers alike. And Sony claims to have engineered the lens to keep 'focus breathing' to a minimum. There's no 'G Master' lens distinction here, but the MTF charts provided by Sony in the press presentation show it outperforming its Canon and Nikon counterparts. Take that with a grain of salt, but it's clear Sony feels strongly about this lens' capability.

At 663 grams it is among the lightest full-frame 24-105mm F4 lenses on the market, as well as the smallest. It is constructed of 17 elements, arranged into 14 groups with 4 aspherical and 3 ED elements. The lens is both dust and moisture resistant and should ship the last week of November. Pricing is set at $1299.

Sony Expands Full-Frame Lens Lineup with New Compact, Lightweight FE 24-105mm F4 G OSS Standard Zoom Covering Wide-angle to Mid-telephoto range

New E-mount FE 24-105mm F4 G OSS Standard Zoom Delivers Serious Still and Video Performance with Compact Design

NEW YORK, Oct. 25, 2017 – Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, has today introduced the latest addition to their expanding full-frame E-mount lens lineup, the FE 24-105mm F4 G OSS Standard Zoom (model SEL24105G).

The new full-frame lens covers the commonly used 24 to 105mm focal length range, delivering outstanding G Lens™ imaging performance with the most lightweight design in its class1, maximizing its versatility and usability. Therefore, the FE 24-105mm F4 G OSS can be used for versatile shooting such as landscape, portrait, wedding and so on. This lens also features fast, precise and quiet autofocus capabilities in both still and video shooting, making it an ideal complement for Sony’s extensive lineup of E-mount cameras.

High Optical Performance and Outstanding Resolution
Sony’s new FE 24-105mm F4 G OSS lens delivers excellent corner-to-corner sharpness throughout the entirety of its zoom range, while also producing beautifully rendered ‘bokeh’ or background defocus at all focal lengths.

This high image quality is made possible thanks to its advanced optical design featuring four aspherical lens elements, two of which are high precision AA (advanced aspherical) lenses. There are also three strategically located ED (Extra-low Dispersion) glass elements that work in combination with the aforementioned aspherical lens elements to minimize chromatic aberration and ensure the ultimate resolution is captured.

The lens also has Sony’s original Nano AR coating to minimize flare and ghosting, and utilizes a circular aperture to ensure it delivers high quality bokeh that is consistent for all Sony’s G series.

Compact, Lightweight Design and Shooting Flexibility
The new FE 24-105mm F4 G OSS lens weighs in at approximately 663 grams (23.4 oz), making it the lightest lens in its class1. When combined with one of Sony’s compact E-mount bodies, it gives photographers and videographers a far more mobile, manageable camera system that greatly increases their shooting flexibility.

In addition to the compact design and versatile 24-105mm focal length, the new lens has a minimum focus distance of 1.25ft, allowing for impressive close up detail. It also includes built-in optical image stabilization to make it easier to produce sharp, blur-free images when shooting handheld.

Highly Advanced and Accurate AutoFocus
In order to keep up with fast-moving subjects, the new standard zoom lens features a DDSSM (Direct Drive SSM) system that is capable of rapid positioning of the lens’ focus groups with high accuracy and very minimal noise. This advanced system combined with a constant F4 aperture at all focal lengths makes the SEL24105G an excellent choice for both still and video shooting.

Further adding to its versatility, the new standard zoom lens also features a customizable focus hold button, a dust and moisture resistant design2 and a fluorine coating on the front element to help minimize dust, water, oil and other contaminants.

Pricing and Availability
The new FE 24-105mm F4 G OSS Standard Zoom Lens will ship this November for about $1,300 US and $1,700 CA.
