Panasonic Lumix 45-175mm f/4-5,6G X Vario PZ

Panasonic's Lumix G X Vario PZ 45-175mm f/4.0-5.6 ASPH. Lens (Black) is a compact 3.8x telephoto zoom lens for Micro 4/3 cameras. With a 90-350mm (equivalent in 35mm format) range, this lens is only 2.42 x 3.54" (61.6 x 90mm) long, and the lens doesn't change length when focusing, thanks to its high tech "Multi Actuator Floating Inner Focus System". It also supports a Power Zoom feature which enables smooth zoom action with just a touch of a button on the lens barrel. This is particularly useful when shooting video.

The lens has a nano surface coating that greatly reduces ghosting and flare, and the two aspherical and two ED lenses deliver improved image quality, with reduced chromatic aberration. A stepping motor and high speed contrast autofocus deliver smooth, accurate autofocus throughout the range.
