PanasonicAGHPX250EJ

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 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.

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 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.

7-Mode Gamma for Richer Gradation

Drawing on technologies developed for the VariCam, Panasonic has equipped the AG-HPX250 with advanced gamma functions that address seven different shooting scenarios, including two Cine-Like Gammas.

• AG-HPX250 Gamma Modes

HD NORM:

Suitable for standard HD recording.

Full-Pixel, Full-Sample AVC-Intra Recording

This is the first handheld camerarecorder to support the AVC-Intra codecs of the P2HD Series for HD recording of broadcast and movie images. Featuring a high compression ratio based on the new MPEG-4 AVC/H.264 moving picture compression technology, this advanced system maintains intra-frame compression to provide both high image quality and excellent editing performance. It offers recording and playback of both AVC-Intra 100 and AVC-Intra 50 modes, and also supports DVCPRO HD recording and playback.
•AVC-Intra 100: 1920 x 1080,* 10 bit, 4:2:2
High-quality images with full-pixel HD and full sampling are recorded at the same bit rate as DVCPRO HD, bringing agile mobility to high-end
production.
•AVC-Intra 50: 1440 x 1080,* 10 bit, 4:2:0
Image quality is the same level as DVCPRO HD, but with the SD (DVCPRO 50) bit rate. You get twice the recording time of DVCPRO HD, and about half the required data transmission time.

* These figures are for 1080i/p mode. The AG-HPX250 also supports 720p mode.

Multi-Format Recording with Native 24p/25p Support and More

•Native recording modes: In addition to 1080/59.94i with the AVC-Intra codec, native recording is supported at 1080/23.98p or 1080/29.97p and 1080/25pN or 720/25pN. In 720p, native recording is possible for both DVCPRO HD and AVC-Intra, making it possible to extend recordinwith pull-down recording.
* Camera image output and playback image output are pulled-down 59.94 (50) frames. 
•Pulldown record mode: This VariCam-compatible mode records*¹ with the DVCPRO HD codec. A 2:3 pulldown is applied to 23.98p, and a 2:2 pulldown is applied to 29.97p, to record 1080/59.94i or 720/59.94p and 1080/25p over 50i or 720/25p over 50p. The 23.98pA (2:3:3:2 advanced pulldown) mode is also supported, allowing editing on applicable nonlinear systems*² with little image degradation.
•59.94Hz/50Hz selector: Supports worldwide HD/SD production.
•SD image acquisition: The DVCPRO 50/DVCPRO/DV multi-codec enables 480/576 image acquisition, with aspect ratio conversion. Select from Side Crop, Letter Box and Squeeze modes.

High Quality/16 bit, 4-Channel Digital Audio

The AG-HPX250 can record high quality/16 bit digital audio on all four channels. You can freely select the audio source for each channel, choosing from built-in mic, external mic and line-in. Level volume is also supported on all four channels.

Double Slot System with Two P2 Card Slots

In addition to allowing continuous recording onto two P2 cards, this system offers the following functions.
• Card select: The recording slot can be switched in Standby mode.
• Hot-swap recording: The card in the standby slot can be exchanged while the other card is being recorded on.

P2 Card Recording Offers High Reliability and a Proven Record for Broadcasting

The P2 card was originally developed for broadcast use. In addition to its large 64 GB* capacity, it strongly resists impacts, vibration and temperature changes, and withstands repeated recording and initialization cycles for extended recording use. The card connector section is designed specifically for professional use, resulting in extremely high durability for insertion and removal. The P2 card and P2HD Series are widely used in broadcast and movie production studios and have a proven track record for reliability, durability and easy operation.

*Total card capacity includes space for data management such as system data; therefore, the actual usable area is less than the capacity indicated on the card.

Versatile MXF File-Based Recording

File-based recording onto memory cards enables high-speed starts, recording starts with no need for cueing, and protection against accidental data overwriting. The recorded data is organized into MXF files. The files can be transferred to a nonlinear editor or over a network without the need for digitizing.*

*PCs must be installed with the included P2 driver in order to mount P2 cards. For editing, PCs must be installed with P2-compatible editing software available from various companies. See "Notes Regarding the Handling of P2 Files Using a PC".

AG-HPX250 Recording Format & Recording Time

*1: Native modes record only the effective frames.
*2: When you select 24 FRAME/30 FRAME in VFR mode in DVCPRO HD 59.94p mode.
*3: When you select 25 FRAME in VFR mode in DVCPRO HD 50p mode.

Variable Frame Rate — Also Supported in 1080p Mode

The Variable Frame Rate (VFR) function was inherited from the Panasonic VariCam, which is widely used for producing movies, TV series, and TV commercials. It creates a wide range of film-camera-like images, such as overcranking for slow-motion and undercranking for quick-motion effects.

Image Modes and Variable Frame Rates

1080/59.94i, 23.98p, 29.97p:

1/2/4/6/9/12/15/18/20/21/22/24/25/26/27/ 28/30 fps (frames per second)

1080/50i, 25p:

1/2/4/6/9/12/15/18/20/21/22/23/24/25 fps

720/59.94p, 23.98p, 29.97p:

1/2/4/6/9/12/15/18/20/21/22/24/25/26/ 27/28/30/32/34/36/40/44/48/54/60 fps

720/50p, 25p:

1/2/4/6/9/12/15/18/20/21/22/23/24/25/ 26/27/28/30/32/34/37/42/45/48/50 fps

• Normal cinematic shooting (at 24 fps, 25 fps or 30 fps) refers to the same rate as used in film cameras. The AG-HPX250 can record in 24 fps. Note that 25 fps and 30 fps are the standard frame rates used in the production of TV commercials, music clips and video media.
• Overcranking (higher-speed shooting) produces a slow-motion effect. This is especially effective for high-action scenes like car chases or crashes, or to create a dramatic impact in a scene. For example, when a scene is shot at 48 fps and played at 24 fps, a slow-motion effect of 1/2x is attained.
• Undercranking (lower-speed shooting) gives you a quick-motion effect. This technique can be combined with a warp-speed effect to give special emphasis to flowing water, fast-moving clouds, etc. For example, when a scene is shot at 12 fps and played at 24 fps, a quick-motion effect of 2x is attained.

Clip Thumbnail Display and Clip Editing

Recorded clips are automatically allocated a thumbnail image and metadata. This lets you display the thumbnail images on the LCD monitor, delete clips, and confirm or edit metadata (using the built-in Software Keyboard function).
• Last clip delete: The clip that was most recently recorded is deleted with a single touch.
• Rec check: The beginning and ending of the clip that was most recently recorded are checked with a single touch.

Shot Marker and Text Memo*¹

• Shot marker: Clips can be marked during or after recording. When mounted to a PC,*² the user can display only the marked clips if desired.
• Text memo: This lets you post a memo on any scene of any clip, up to 100 memos in all, similar to a sticky note.

*1: Shot marker and text memo cannot be used in loop rec, interval rec, or one-shot rec. 
*2: When using P2 viewer, a Windows PC viewing application that can be downloaded free of charge by P2 users. For details, see "P2HD series".

One-Clip Rec Mode

Whereas normal Rec mode produces a clip for each Rec start/stop cut, One-Clip Rec mode records up to 99 consecutive cuts as a single clip, which greatly improves the nonlinear editing work that follows. A text memo is automatically attached when recording begins, making it easy to find desired cuts within the clip.

Recording Modes That Meet a Wide Variety of Needs

• Loop rec: This repeatedly re-records a particular recurring time slot, always maintaining a recording of the most recent period.
• Pre-rec*: While in standby mode, you can continuously store, and subsequently record, up to 3 seconds in HD (7 seconds in SD). This will
help you to get the shot you want every time.
• Interval rec*: This gives you automatic intermittent recording based on a set interval and recording time.
• One-shot rec*: This frame-shot recording function is useful for producing animations.
• Time stamp: The date and time can be stamped onto recorded images. Commonly used for evidential images.

* These functions cannot be used during Variable Frame Rate recording.

Multi-Camera Synchronizing with Genlock IN and TC IN/OUT

The AG-HPX250 is the first handheld camera recorder to support multicamera synchronizing. It features a built-in SMPTE time-code generator/ reader, TC input/output, and Genlock input, ideal for multi-camera live relay and recording systems.

Digital A/V Output with SDI and HDMI

• SDI OUT (HD/SD): Allows camera-through output during HD/SD recording, or outputs high-quality 10 bit, 4:2:2 images for playback of
AVC-Intra 100 footage. Includes embedded audio, and supports Rec S/S linked backup recording with a Panasonic recorder equipped with HD SDI input. When outputting SD SDI down-converted from an HD source, the Aspect Ratio Conversion mode can also be selected.
• HDMI OUT: This is a next-generation interface for HD video and audio. It allows digital A/V output from a wide range of devices with both
professional and consumer specifications.
• VIDEO OUT: SD composite output. HD playback is down-converted.

Other Interfaces

• USB 2.0 HOST: This allows files to be copied between an external HDD and a P2 card *¹, and lets you view the thumbnails of P2 files saved onto the HDD.
• USB 2.0 DEVICE: Uploads P2 card files to a PC/Mac.
• DVCPRO/DV (IEEE 1394): Enables backup recording and dubbing by inputting or outputting a DV stream, including DVCPRO HD.*²
• Camera Remote: Controls focus, iris, zoom and REC start/stop.
• XLR audio input: 2-channel mic/line inputs supporting 48V phantom power supply.

*1: AG-HPX250EJ does not support to copy the files onto a P2 card via USB 2.0. 
*2: Excluding 720p native mode. Does not support AVC-Intra input/output. Also does not output loop rec, interval rec or one-shot rec content. AG-HPX250EJ does not support input.
