The LUMIX G X VARIO PZ 45-175mm/F4.0-5.6 ASPH./POWER O.I.S. (H-PS45175) is a new cutting-edge interchangeable lens with electric-powered zoom operation that complies with Micro Four Thirds System standard. The new premium lens brand “X” features superb image rendering for lifelike textures, crisp edge-to-edge contrast, and includes 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 minimizes 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..***

** 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.
