G Lens Image Quality

Designed for demanding visual creators, this ultra-wide zoom offers no compromises regarding image quality, autofocus performance, or movie-making functionality.

Enhanced Autofocus and Video Capabilities

Offering an enhanced feature set for both still photography and videography, the sel2070g delivers fast focusing performance, improved tracking, and a series of attributes specifically designed for videographers.

• Two XD (extreme dynamic) linear motors provide smooth, silent, and precise autofocus performance as well as improved tracking performance for photos and videos.
• Internal focusing system maintains the overall length of the lens and does not rotate the lens barrel while focusing, enhancing the use of circular polarizers and variable ND filters.
• Updated optical design effectively eliminates focus breathing, focus shift, and axial shift to prevent unwanted movements and angle of view variations during movie recording.
• Aperture ring with On/Off click switch and iris lock switch prevents the aperture ring from being accidentally moved between the f/4 and f/22 settings.
• Optimized for filming, the lens supports active mode image stabilization and micro-step aperture control for smooth and seamless video capture.
• Two programmable focus hold buttons and a focus mode switch for intuitive focus control.
• Minimum focusing distance of 9.8" with excellent close-up performance at all focal lengths.
