Sony E-Mount
Both are travel zooms for Sony E APS-C with stabilization, but they are built for different jobs. The E PZ 18-105mm f/4 G OSS (2013) is a G lens with a motorized zoom, constant f/4 and a length that does not change while zooming. Sony markets it for video because the zoom runs smoothly via a lever. According to Sony it weighs 427 g. The E 18-135mm f/3.5-5.6 OSS (2018) is a light all-rounder with a 7.5x zoom instead. It reaches 135 mm and weighs only 325 g, but opens only to f/5.6 at the long end.
