Panasonic H-PS45175K 45-175mm f/4.0-5.6 Micro Four Thirds power zoom lens

Premium compact telephoto zoom for Micro Four

This Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 lens brings a 3.9× power zoom range to the Micro Four Thirds system, covering standard to telephoto perspectives in a single unit. The motorised zoom mechanism is tuned for smooth, silent focal-length changes during recording, while the floating inner-focus design keeps the lens compact at approximately 90.0 mm long. It suits hybrid shooters who want one lightweight optic for both stills and video without swapping glass.

45 to 175 mm focal range

The zoom spans 45 mm at the wide end through 175 mm at the telephoto end, delivering a versatile 3.9× magnification factor for framing flexibility. Maximum aperture opens to f/4.0 at 45 mm and narrows to f/5.6 at 175 mm, providing usable depth-of-field control across the range. Close-focusing capability reaches 0.20× magnification for detail work, while the 46 mm filter thread accepts standard circular polarisers or ND filters. Optical image stabilisation adds up to several stops of shake correction for handheld telephoto shots.

Optical stabilisation

The built-in Power O.I.S. unit compensates for camera movement without adding audible whir, and the multi-actuator floating inner-focus system moves smaller lens groups rather than the entire barrel, reducing mechanical friction during autofocus. At roughly 210 g the lens adds minimal mass to a gimbal or handheld rig, and its all-internal zoom action prevents balance shifts while recording. Power draw comes solely from the camera body through the Micro Four Thirds mount, so no external batteries or cables are required for normal operation.
