Sony SELP18105G E PZ 18-105mm F4 G OSS camera lens

Compact power-zoom lens for Sony E-mount

The Sony SELP18105G is a mid-range zoom covering 18-105 mm with a constant f/4 maximum aperture. It fits Sony NEX and other E-mount APS-C bodies, delivering a 27-158 mm equivalent field of view. Built-in Optical SteadyShot stabilization and a quiet power-zoom mechanism suit both stills and video work. The lens uses two extra-low dispersion and three aspherical elements in a 72 mm filter thread.

Suited to solo shooters needing one lens for wide

This lens serves creators who want a single, stabilised zoom for travel, events or documentary work without changing glass. The power zoom gives smooth focal-length transitions for video, while the constant f/4 aperture keeps exposure consistent across the range. Photographers who need wider than 18 mm, faster than f/4, or a longer reach than 105 mm should look at alternative optics. Full-frame shooters will see vignetting because the image circle covers APS-C only.

Constant f/4 aperture through the zoom range

The defining specification is the fixed f/4 maximum aperture from 18 mm to 105 mm, which maintains exposure and depth-of-field control while zooming. Variable-aperture zooms typically drop to f/5.6 at the long end, forcing ISO or shutter-speed compromises. This constant aperture, combined with power zoom and Optical SteadyShot, makes the lens a deliberate choice for run-and-gun video and consistent stills performance.
