The Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 HD is a newer Lumix G series lens which covers an extensive tele-photo zoom range
Overall this is a slightly confusing lens. It packs a solid performance into a compact and lightweight body. The power-zoom rocker is an interesting addition but having to resort to the camera menu to control the OIS system is annoying (as it is on other cameras that use in-body image stabilisation). Probably the cleverest parts of this lens are tucked away inside, leaving only a modest but very competent face visible to the world.
