G Lens Image Quality

Tailored for discerning visual artists, this ultra-wide zoom lens ensures exceptional image quality, reliable autofocus performance, and robust movie-making capabilities without compromise. Specifically designed for full-frame Sony E-mount mirrorless cameras, it boasts a constant f/4 maximum aperture that guarantees uniform illumination across the entire zoom spectrum.

Equipped with two XD (extreme dynamic) linear motors, this lens offers smooth, silent, and accurate autofocus, along with superior tracking performance for both images and videos. Its internal focusing mechanism preserves the lens's overall length and prevents the lens barrel from rotating during focusing, which is beneficial for the use of circular polarizers and variable ND filters. 

The revised optical design effectively mitigates focus breathing, focus shift, and axial shift, thereby avoiding any unintended movements or variations in the angle of view while recording films. The aperture ring features an On/Off click switch and an iris lock switch to prevent accidental adjustments between the f/4 and f/22 settings. Specifically optimized for video production, the lens accommodates active mode image stabilization and micro-step aperture control, facilitating smooth and seamless video recording. Additionally, it includes two programmable focus hold buttons and a focus mode switch for intuitive focus management. The lens boasts a minimum focusing distance of 9.8 inches, delivering exceptional close-up performance across all focal lengths.

Handling and Design

This ultra-wide standard zoom lens is both compact and lightweight, providing a versatile and expansive field of view ideal for everyday photography. Its hybrid construction combines metal and plastic elements to enhance durability while maintaining a lightweight profile. The front lens element features a fluorine coating that effectively repels water, dust, fingerprints, and other contaminants, facilitating easier cleaning. Additionally, the lens is designed to be resistant to dust and moisture, incorporating a rubber seal around the lens mount to ensure reliable performance in adverse weather conditions.
