LUMIX G X VARIO PZ 45-175mm / F4.0-5.6 ASPH. / POWER O.I.S.
It's a new cutting-edge interchangeable lens LUMIX G X VARIO PZ 45-175mm/F4.0-5.6 ASPH./POWER O.I.S. (H-PS45175) with electric-powered zoom operation from the new premium lens brand “X” for LUMIX G Micro System that complies with Micro Four Thirds System standard. Crystallizing Panasonic's optical technologies, new premium lens brand “X” features superb image rendering for lifelike textures, crisp edge-to-edge contrast, a unique Nano Surface Coating for minimal ghosts and flaring and natural atmospheres with remarkable transparency.

The industry’s first adoption of Multi-Actuator Floating Inner Focus System* which controls 3 lens groups separately by the individual actuator achieves downsizing in both size and weight. It also achieves high descriptive performance for resolution and contrast at entire zoom range 45-175mm (35mm camera equivalent: 90-350mm) without changing the overall length.In addition, the lens system features the inclusion of 2 ED lenses, which suppress chromatic aberration, contributing to high descriptive performance at entire zoom range.

Panasonic's Nano Surface Coating technology is adopted to minimize the reflection at entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in the super clear image with dramatic reduction of ghost and flare.

Adopting an inner focus system driven by a stepping motor, the superior optical design realizes outstanding smoothness to support the Light Speed AF of approx. 0.15 second**. By speeding up the aperture control, shutter time lag is also shortened by approx. 20% compared with the LUMIX G VARIO 45-200mm /F4.0-5.6/MEGA O.I.S..***

* For a digital interchangeable lens as of August 26, 2011./ ** The time for focusing on the subject is measured with the DMC-GF3 to move the lens position to ""2m"" from ""infinity"" position at wide-end. Panasonic measurement method. ****/ *** Measured with DMC-GF3. The time required to start exposure after the shutter button is fully pressed after the lens position is moved from “infinity” to “2m” at wide-end. ****/ **** The firmware of the GF3 must be updated to Ver.1.1 or later. Panasonic measurement method.

Dynamic photos and videos
Weighing in at just 210g, this ultra-compact power zoom lens covers the entire medium-telephoto to telephoto range. It is a member of the premium LUMIX “X” lens brand – ensuring dynamic expression with every shot you take. The smooth power zoom and super-fast auto focusing, together with advanced image stabilisation, make this lens ideal for fast-moving subjects or even hand-held film recording.

POWER O.I.S. – ultra-sharp photos
Capture scenes carefree or at the spur of the moment. The optical image stabilisation (O.I.S.) technology built directly into the lens ensures your photos will look great, with sharp blur-free contours across the entire picture.
Taking highly popular MEGA O.I.S. further, this advanced technology immediately compensates even large camera shake and vibrations that may occur in photography. So you can capture true-to-life scenes without the need for a tripod. In the end, you’ll enjoy wonderfully crisp images.

Nano Surface Coating - clarity from all angles
Put an end to unwanted ghosting and flaring – the Nano Surface Coating has been applied to lenses within the system. This special, ultra-thin coating was developed originally by Panasonic to reduce bothersome reflections across the entire light spectrum. The result: crystal-clear pictures even if you’re photographing a light source in the dark.

Power Zoom - the smart way to zoom
With this feature, you have yet another smart Panasonic innovation. That’s because lenses with Power Zoom have a fully automatic, integrated motor that drives the zoom function – making for easy zoom operation. This is especially great to have when recording a video: for example, you can determine the speed of the zoom so that you can capture subjects precisely even when zooming slowly. The motor is also whisper-quiet for more enjoyable, subtle shooting.

HD Video Support - perfect video-recording
With HD video support any user has everything they need for recording with their LUMIX camera. Not only does it perform smooth aperture changes so there are no sudden jumps in exposure, it also boasts a silent design for enhanced capture of the scene’s audio. What’s more, it offers excellent tracking performance – so you won’t miss a moment of the action.

H-PS45175 - 14 elements in 10 groups
- 2 aspherical lenses
- 2 Extra-Low Dispersion lenses
Aspherical (ASPH) lenses reduce size and weight, effectively preventing spherical and distortion aberration.
Extra-Low Dispersion (ED) lenses correct chromatic aberration rendering sharp, high-contrast images with clear colors from corner to corner.
