AG-HPX250
P2 Handheld Memory Card Camera Recorder
(AG-HPX250P, AG-HPX250EJ, AG-HPX250EN)
Shoulder-Type Performance and Functions
in a Professional Handheld Camera Recorder
The high-performance AG-HPX250 P2 handheld fills out the P2HD Series by incorporating the newest technologies throughout — in the lens, camera and recorder sections. The newly developed 22x zoom lens covers a wide shooting range, from wide-angle to telephoto, and features three manual rings for precise control. Imaging is optimized by the high-sensitivity, low-noise 1/3-type 2.2-megapixel U.L.T. (Ultra Luminance Technology) 3MOS image sensor. And the AG-HPX250 is the first handheld model to support AVC-Intra codecs. This combination produces a level of performance that rivals many full-size shoulder-type camera recorders, and adds the high-quality acquisition of Full-HD (1920 x 1080) and 10 bit, 4:2:2 full sample, broadcast-level images. Image expression is also boosted by the Variable Frame Rate (VFR) function, and system expansion for broadcasting and other production applications is provided by multi-camera synchronizing. The stylish design of the AG-HPX250 adds further to both mobility and operating ease, and opens a new stage for news gathering and image acquisition.

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.
Optical Image Stabilizer, Digital Zoom, and ND Filter
•Hand-shake correction with the Optical Image Stabilizer (OIS).
•Digital Zoom function.* It can be assigned to an user button and close up to 2x, 5x, and 10x. In combination with the optical zoom, this function provides a telephoto capability up to 220x.
•Four-position (OFF, 1/4 ND, 1/16 ND, 1/64 ND) optical neutral density filter wheel.
* 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
U.L.T. image sensor
High-Sensitivity F10*, 2.2-Megapixel, Low-Noise U.L.T. Image Sensor and Optimized Signal Processing Circuit
The AG-HPX250 features 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. Progressive Advanced Processing (PAP) technology, which is driven by 3D adaptive processing, has also been further refined to enable high-sensitivity F10*, low-noise shooting in dimly lit places.
*AG-HPX250 sensitivity is selectable, F10 is PAP Filter Type1 and F7 is PAP Filter Type2 in 59.94Hz mode. In 50Hz mode, F11 is PAP Filter Type1 and F8 is PAP Filter Type2. The default setting is PAP Filter Type2.
Flash Band Compensation
In contrast with the CCD image sensor, which accumulates still images of single frames that are exposed with identical timing, the MOS image sensor uses a rolling shutter system that sequentially scans each line of 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-HPX250 is 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 High-Quality DSP Matches Image Processing and Quality to match Each Shooting Situation
20 bit Digital Signal Processor
The AG-HPX250 incorporates a high-performance 20 bit DSP that handles image rendering processes such as gamma and various detail
enhancement functions with DSP Processor exceptional precision.
Dynamic Range Stretch (DRS)
In scenes with mixed contrast, such as when panning from indoors to outdoors, the DRS function automatically suppresses blocked shadows and blown highlights. A gamma curve and knee slope are estimated to match the contrast of each pixel, and applied in real time. When dark, bright, and intermediate shades are all contained in the same scene, this produces excellent gradation for each shade and minimizes blocked shadows and blown highlights.
* The DRS function does not operate in 1080/24p, 1080/25p or 1080/30p mode.
