Quick Take: A feature-stripped version of the more expensive PV-GS250, the PV-GS150 is more compact than its sibling but lacks the GS250's optical stabilization; it uses electronic. They use the same set of three 800,000-pixel CCDs, but Panasonic's interpolation technology translates into different still photo resolutions for each, and they have different lenses. The GS150 also lacks a manual focus ring and an S-Video input connector; therefore, you can't use the GS150 for analog-to-digital video conversion. Because of the differences in lens and stabilizer technologies, you can expect different video quality than the GS250's.
