22x Panasonic Lens — Zooming in on New Levels of Image Expression

Packed with Panasonic Optical Technology

The high-performance zoom lens was developed specifically for professional HD video production. While inheriting the wide-angle capabilities of the DVX and HVX Series, it adds the same level of operating ease as you'd expect from an interchangeable lens model for broadcasting and other professional uses. Combining 18 lens elements in 12 groups, this advanced lens unit further adds a UHR (Ultra High Refractive) glass element, a low dispersion element and aspherical lenses. This newest optical technology can provide high resolution.

In addition, it is combined with a unique Panasonic digital signal processing technology called Chromatic Aberration Compensation (CAC) to minimize color bleeding in the surrounding image and achieve rich expression with finely rendered nuances and excellent shading. Zooming from 28mm to 616mm (35mm equivalent), this 22x zoom lens covers a wide field of view, from wide-angle to telephoto, without a conversion lens.

Three Manual Rings — Zoom, Focus and Iris

The lens unit is provided with three rings — a mechanical (cam-driven) zoom ring, a focus ring, and an iris ring. You can operate them manually almost like an interchangeable lens including rugged operation of zoom ring.

*The digital zoom cannot be used while operating the Dynamic Range Stretch (DRS) or Scan Reverse functions. If either function is operated while digital zooming, the zoom will be automatically turned off.

Also, Flash Band Compensation (FBC) will not operate while digital zooming.

High-Sensitivity, Low-Noise U.L.T. Image Sensor

pixels. This lowers power consumption and enables high-speed drive, but because the exposure timing differs for each line, when an external flash is used, it tends to produce images where the brightness is divided between the top and bottom of the image. This is called the flash band effect. The AG-HPX255/HPX250 are equipped with highly accurate flash band detection and compensation software. By generating pairs of frames containing flash bands, and frames in which a flash extends from the previous frame to the entire screen, and then using the compensation process to adjust the level, the flash band effect of MOS-based imagers is eliminated.

The AG-HPX255/HPX250 feature the Ultra Luminance Technology (U.L.T.) 1/3-type 2.2-megapixel 3MOS image sensor that is incorporated in our shoulder-type P2HD camera recorders. This advanced image sensor is set to maximize the performance of the lens and signal processing circuit under standard shooting conditions.
