Panasonic Lumix G X Vario 45-175mm f/4-5.6 ASPH. HD PZ Power O.I.S. Lens for MFT (Micro Four Thirds), Black {46}

45-175mm MFT zoom with electronic power zoom for video

The Panasonic Lumix G X Vario PZ 45-175mm f/4-5.6 ASPH. covers an useful telephoto range on Micro Four Thirds bodies, giving you an effective 90-350mm field of view equivalent. The f/4-5.6 variable aperture keeps the lens compact, and the 46mm filter thread means polarizers and ND filters stay affordable. Aspherical elements in the optical design work to control distortion and aberration across that zoom range.

The defining feature here is the power zoom mechanism. Unlike a manual zoom ring, the electronic drive delivers smooth, consistent zoom speed during recording, the kind of controlled, repeatable movement that manual zooming rarely achieves on a run-and-gun shoot. HD PZ Power O.I.S. adds optical stabilization, which matters when you're shooting handheld at the long end. This is a lens built with video in mind from the ground up, and the MFT mount means it pairs with a wide range of Panasonic and Olympus bodies. Released in 2011, it has years of real-world use behind it in the MFT ecosystem.

Who It's For

Video shooters working handheld who need smooth zoom transitions will find the power zoom mechanism directly addresses their biggest challenge with telephoto work. Event videographers benefit from the stabilized 175mm reach when covering stages or ceremonies from a fixed position. Mirrorless photographers shooting wildlife or sports from a distance get a compact telephoto that doesn't add bulk to a travel kit. Micro Four Thirds hybrid shooters who split time between stills and video get a single lens that handles both without switching systems.

FAQ

What's the effective focal length range on a Micro Four Thirds body?

45-175mm becomes 90-350mm equivalent on MFT's 2x crop factor, giving you a telephoto range that covers everything from moderate telephoto to serious reach without needing a separate lens.

Why would I choose power zoom over a manual zoom ring?

Power zoom delivers consistent, repeatable zoom speed during recording-manual zooming is jerky and hard to control on handheld video. If you're shooting run-and-gun, the electronic drive handles the smoothness for you.

Does the lens have image stabilization?

Yes. HD PZ Power O.I.S. provides optical image stabilization, which matters when you're handheld at 175mm where any camera shake amplifies on screen.

What aperture should I expect at the long end?

The aperture drops to f/5.6 at 175mm. The variable f/4-5.6 design keeps the lens compact, but you'll need good light or higher ISO at full extension.

Will my filters screw on easily?

The 46mm filter thread is standard, so polarizers, NDs, and other glass stay affordable and easy to swap between lenses.

Is this lens designed primarily for video?

Yes. The power zoom mechanism, smooth O.I.S., and compact design point squarely at video work. It pairs well with Panasonic and Olympus MFT bodies used for run-and-gun shoots.

How old is this design?

Released in 2011, the design has years of real-world use behind it in the MFT ecosystem, and the optical formula has held up in the field.
