The Sony 18-110mm F4 G OSS Power Zoom Lens (SELP18110G) is a high-performance zoom lens built specifically for video and cinema creators using Sony E-mount Super 35mm or APS-C cameras. With an equivalent full-frame focal length of 27–165mm, it covers a wide range of shooting needs from wide-angle establishing shots to tight portraits and close-ups—all with a constant F4 aperture that delivers consistent exposure and depth of field across the entire zoom range.

Designed for professional filmmaking, the lens features Sony’s Smooth Motion Optics (SMO) technology that reduces focus breathing, axial shift, and image shift while zooming or focusing—critical for seamless scene transitions. The integrated Power Zoom (PZ) mechanism ensures smooth, gradual zooming at variable speeds, perfect for cinematic zoom-ins or outs during takes.

The dual focus system supports both auto and manual operation with responsive, linear manual focus control and minimal delay—making it ideal for precise rack focus work. The focus ring is fully decoupled for repeatable and smooth manual focus adjustments.

Optically, the lens is part of Sony’s G Lens series, incorporating advanced aspherical elements and extra-low dispersion glass to minimize aberrations and enhance resolution and contrast. The built-in Optical SteadyShot (OSS) image stabilization helps maintain stable video, even when shooting handheld or on-the-go.

With a robust and compact design, the lens features a parfocal construction, ensuring the focus remains constant while zooming, which is essential for professional video workflows. It also includes a zoom/focus selector switch, customizable focus ring torque, and support for follow-focus and matte box systems.

Whether you're filming documentaries, commercials, narrative films, or corporate videos, the Sony SELP18110G provides the focal length flexibility, mechanical precision, and optical quality that professional videographers demand.
