I always thought the point of mirrorless was to make things compact, but Panasonic looks like they want to expand my mind and believe it also means raw power, as they have announced the Lumix DMC-GH4, a new camera that features 4K 24p cinematic video (4096x2160), plus 4K 3840x2160 30p/24p with 49 points of autofocus. The build is all metal, and it's obviously aimed at the professional market.
The 16.05-megapixel Digital Live MOS Sensor is built for high sensitivity image recording with quick response. An approximately 50% higher speed signal readout suppresses the effect of a rolling shutter when using electronic shutter or recording video. The Live MOS Sensor delivers an expanded gradation range by a maximum1/3 step at low ISOs. Superior noise reduction allows for exposures up to 60 minutes long.
It's Wi-Fi and NFC compatible, and with the Panasonic Image App, remote photo and video shooting is available with a compatible smartphone or tablet, and can easily add embed geotag data in an image after shooting.
The Panasonic LUMIX GH4’s Venus Engine image processor is equipped with a quad-core CPU that delivers high speed signal processing. Combined with the Digital Live MOS Sensor, you’ll enjoy dramatically improved sensitivity (maximum ISO 25600), gradation performance, resolution, and color reproduction while achieving exceptional picture quality with a natural look and feel that LUMIX is famous for.
The Panasonic LUMIX DMC-GH4 doesn't go all Sony a7R on us, and keeps an electronic shutter. The high-speed signal readout from the Live MOS Sensor minimizes rolling shutter effect. The Silent mode switches the shutter from mechanical to electronic and turns off sounds, while suppressing the AF assist lamp and flash with just a single setting for special shooting occasions.
SMPTE-compliant Time Code in Rec Run or Free Run makes it easy to synchronize multiple videos or sound sources in the postproduction process.
Color Bars & 1KHz Test Tone
Color Bars (SMPTE / EBU / ARIB Standard) are used as a benchmark for fixing color or brightness. 1KHz Test Tone is used as a benchmark for fixing sound or volume.
Center Marker works as a guide mark for video image composition. Simply display it at the center of the viewing angle.
Use Synchro Scan to suppress flicker over the TV / PC monitor, or when shooting under fluorescent lights.
“CINELIKE D” and “CINELIKE V” create a cinema-like tone to expand your creativity.
Use Master Pedestal to adjust the brightness balance ±15 steps based on the color black.
Determine overexposed areas with the Zebra Pattern before or during shooting. This pattern can even be output to the external monitor too.
The aformentioned video records in MOV/MP4, or ultra high bitrate video recording at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) without a recording time limit.
Focus Peaking shows the peak of focus in MF and AF+MF mode. Users can see the peak of focus while monitoring the subject in live view. Focus Peaking is also available in remote photo / video shooting with a smartphone or tablet via Wi-Fi.
Highlight and shadow can be separately adjusted with the front or rear dial. Three patterns of settings can be customized in addition to 3 preset patterns.
The Panasonic LUMIX DMC-GH4 boasts high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for 2,359K-dot LVF (Live View Finder) of approximately 1.34x / 0.67x, and 3.0-inch 1,036K-dot free-angle rear monitor. These superior displays achieve high-speed response with minimum time lag while enhancing resolution. The OLED for the LVF boasts 10,000:1 high contrast for superior color reproduction.
The Venus Engine image processor dramatically boosts performance with a quad-core CPU, enabling high-speed signal processing required for rich video recording such as 4K. Integrating superior noise reduction systems, DMC-GH4 successfully shoots at a maximum ISO 25600. Sensitivity, gradation performance, resolution, and color reproduction are dramatically improved to achieve even higher picture quality.
Pricing on any of this stuff isn't yet available, but you can start guessing! What do you think it will retail for?
