Hands-on preview: Panasonic Lumix GH4

Door -

Eerder deze week waren te gast bij Panasonic. Onder embargo lieten ze ons en enkele andere media hun nieuwste aanwinst zien: de Panasonic Lumix GH4. Niet GH4K zoals in de geruchten geopperd werd. Die naam had overigens prima gekund, want dit is daadwerkelijk de eerste consumentencamera die in 4k video kan opnemen. Er zijn geen andere camera’s die dat kunnen. De door ons eerder besproken GoPro Hero 3(+) Black Edition actiecamera (review) ondersteunt weliswaar de 4k resolutie, maar dan slechts met 15 bps wat voor serieuze video niet echt bruikbaar is. Wie volwaardig in 4k wil opnemen moet nu bijna € 4000 neertellen voor de Blackmagic videocamera. In die zin ontketent Panasonic hiermee een revolutie!

De toekomst van video is 4k

Niemand kan er meer omheen: de toekomt is 4k. Full HD is ingeburgerd en de tijd is rijp voor een nieuwe stap omhoog. Er is al een redelijk aanbod van 4k tv’s en dat zal alleen maar toenemen. Ook streaming diensten als Netflix gaan op korte termijn films in 4k kwaliteit aanbieden. Als je zo’n 4k tv hebt en gewend raakt aan de kwaliteit, dan wil je ook niet meer in Full HD filmen. De overgang van 1080p naar 4k is weliswaar visueel minder groot dan van SD naar HD, toch is het wel degelijk merkbaar. Films zien er veel realistischer uit dankzij de toegenomen scherpte. Maar vergeet vooral foto’s niet. Op dit moment staar je op je hdtv naar een schamele 2 megapixels terwijl je camera een factor 10 meer resolutie biedt. Met 4k springen we in een keer naar 8 megapixels en voor foto’s is dat echt een enorm verschil. Het kon dan ook niet uitblijven dat in 2014 de markt overspoeld wordt met 4k producten. Panasonic is nu de eerste die 4k aanbiedt in een ‘betaalbare’ consumentencamera, maar er zullen absoluut nog meer fabrikanten volgen.

Specificaties Panasonic Lumix GH4

Maar goed, op naar de Panasonic Lumix GH4, want is er nog veel meer te vertellen dan alleen over 4k video. Panasonic benadrukt dat de GH4 óók echt een fotocamera is. Zowel het foto- als videodeel is flink verder ontwikkeld zodat de camera beide doelgroepen volledig aanspreekt. De camera ziet er op het eerste gezicht identiek uit als de GH3, maar dat is slechts schijn. Van binnen is de camera volledig op de schop gegooid. Een compleet nieuwe autofocus methodiek speelt daar een centrale rol in, maar daarover later meer.

  • Nieuwe 16 megapixel-sensor (max. ISO 25.600)
  • Nieuwe Venus beeldprocessor
  • Vernieuwde autofocus (van 4,3 naar 7 bps met af-tracking)
  • 12 bps burst
  • Sluiter gegarandeerd tot 200.000 opnamen
  • Stille modus
  • Touchscreen (met touch af)
  • Sterk verminderde ‘rolling shutter’ (dankzij snellere sensor en processor)
  • Betere prestaties op hoge ISO’s
  • Verbeterde kleurproductie
  • 2360k dot OLED EVF
  • 1040k dot OLED lcd-scherm (GH3: 640k dot)
  • Autofocus mogelijk tot -4 EV (=-zeer donkere lichtomstandigheden)
  • Stof- en spatwaterdicht
  • Wifi en NFC
  • Geotagging via smartphone app
  • Video: 100 Mbps IPB, 200 Mbps ALL-I (mov, mp3, avchd)
  • Ongecomprimeerde video, 4:2:2 in 8- en 10-bit
  • Externe interface unit (met XLR input)
  • SD class 10 UHS III noodzakelijk voor 4k

Sensor

Hoewel de sensor exact hetzelfde aantal megapixels biedt, is deze volgens Panasonic wel helemaal vernieuwd. In tegenstelling tot wat de trend is, heeft Panasonic er bewust niet voor gekozen om het anti-alias (low-pass) filter van de sensor te verwijderen. Ze hebben hier wel mee geëxperimenteerd, maar de resultaten waren niet naar wens. Bij camera’s van met name Nikon en Sony van 24 en 36 megapixels zien we steeds vaker het anti-alias filter verdwijnen. Dit levert scherpere plaatjes op maar kan ook zorgen voor negatieve bijeffecten zoals moíre (streepjespatronen), hoewel dit in de praktijk vaak meevalt – mede dankzij de hoge resolutie. Dankzij verbeterde ruisreductie is ook de kwaliteit op hoge ISO’s verbeterd. Panasonic liet ons ter vergelijking een aantal foto’s op A3 formaat zien waarbij ook een vijftal concurrenten waren meegenomen. Zelfs tegenover fullframe camera’s kon de GH4 zich goed staande houden op het gebied van ruis, kleurechtheid en huidtinten (al waren de fullframe’s op hoge ISO’s wel beter). Volgens eigen zeggen biedt de GH4 betere beeldkwaliteit dan APS-C camera’s. Of de resultaten in RAW ook significant verbeterd zijn zouden we moeten testen.

Autofocus

Los van 4k, de sensor, de EVF en de verbeterde specificaties is de autofocus de meest spectaculaire verbetering van de GH4. Dat komt omdat Panasonic een nieuwe methode heeft bedacht om scherp te stellen die vooral voor tracking zeer van belang is. Camera’s die afhankelijk zijn van constrastdetectie (zoals de meeste systeemcamera’s en DSLR in live view-modus) waren vooral met tracking erg traag, waardoor traditionele DSLR’s (die fasedetectie autofocus gebruiken) op dat vlak altijd sneller waren. Panasonic gebruikt een ‘defocus’ methode waarbij de afstand tussen twee onscherpe afbeeldingen gemeten wordt. Dit zou zo snel zijn dat de GH4 op dat vlak niet meer onder zou doen voor snelle DSLR’s. De GH4 kan 7 foto’s per seconde maken met behoud van volledige af-tracking (zonder: 12 bps). Als hulpmiddel gebruikt Panasonic hiervoor een database van alle Lumix lenzen om de autofocus optimaal te tunen. Het was nog niet duidelijk of dit ook met andere M43 lenzen zou werken (zoals die van Olympus). Reken er vooralsnog maar niet op.

Hands-on

We hebben enige tijd met de Pansonic Lumix GH4 kunnen spelen. Het betrof echter een pre-productiemodel in een vroeg stadium dat nog niet geschikt was om serieus mee aan de slag te gaan, wat ook wel te merken was. Aangezien de beschikbaarheid nog een paar maanden duurt was dat niet verwonderlijk. De body voelt vertrouwd aan doordat deze erg lijkt op de GH3. Maar meteen viel al één forse verbetering op: de OLED EVF met 2360k beeldpunten ziet er bijzonder goed en scherp uit. Ook is het beeld relatief groot zodat je goed kunt zien wat je doet. De menu-indeling is hetzelfde en die kan ondertussen wel een opfrisbeurt krijgen (er zijn zoveel mogelijkheden dat je makkelijk verdwaalt). Het programmawieltje bevat een extra knop waarmee je hem kunt vergrendelen.

Video

Wie in 4k wil gaan filmen heeft daar wel specifieke SD-kaarten voor nodig. Panasonic adviseert class 10 en UHS-III (het herkennen aan het cijfer 3 onder class 10). Deze kan met 90 MB/s lezen en 45 MB/s schrijven en dat is voor 4k geen overbodige luxe. De buffer van een UHS-I class 10 kaart is veel lager, waardoor deze niet geschikt is voor 4k. Panasonic gebruikt geen pixel binning om de resolutie van de sensor te verlagen naar de videoresolutie (8 mp voor 4k), maar cropping. Dat heeft als voordeel dat de pixels 1:1 gebruikt worden en er geen herberekening nodig is, wat ten goede moet komen aan de kwaliteit. Het betekent wel dat je wat groothoek verliest (-17% FOV). 4:2:2 wordt in 8- en 10-bit ondersteund, maar wie in 10-bit wil opnemen heeft daarvoor wel een externe recorder nodig. Ook nieuw is een aparte ‘Interface Unit’ die je onder de camera kunt bevestigen. Dit biedt meer mogelijkheden voor video (zoals XLR, ongecomprimeerde video, externe opslag, etc.). Ook werd er een nieuwe flitser aangekondigd met een ingebouwde LED-lamp voor video. Ook een aparte LED-lamp is beschikbaar.

Prijs en beschikbaarheid Panasonic Lumix GH4

De Panasonic Lumix GH4 komt in april voor het eerst op de markt, maar voor Nederland en België wordt dat mei. De prijs werd tijdens onze preview nog niet bekend gemaakt, maar zou volgens Panasonic ‘scherp’ zijn, zodat de camera zowel voor filmers als fotograferen toegankelijk blijft. In de wandelgangen wordt gesproken over een prijs ‘onder de $2000’, wat een straatprijs van € 1500 tot € 1800 zou kunnen betekenen. De GH3 blijft overigens gewoon te koop. Vermoedelijk schuift die dus iets naar beneden in prijs, zodat de GH4 voor een meerprijs het high-end segment moet aanspreken.

PERSBERICHT

A Digital Single Lens Mirrorless (DSLM) Camera DMC-GH4

with New AF Technology and the World’s First* 4K Video Recording Capability

To Meet Professional Needs for Both Photography and Videography

 *For a digital single lens mirrorless camera as of February 7, 2014.

Panasonic is proud to introduce an ultimate photo/video hybrid Digital Single Lens Mirrorless(DSLM) camera DMC-GH4 for the successor of DMC-GH3 that created an industrial sensation with its outstanding video recording performance. The image quality for both photo and video is dramatically improved by crystallizing Panasonic’s cutting-edge technologies.

The newly developed 16.05-megapixel Digital Live MOS Sensor for DMC-GH4 excels both in sensitivity and response and suppresses rolling shutter effect even when using electronic shutter or recording motion image. The image processor Venus Engine is also newly developed dramatically boosting its performance with new quad-core CPU that lets high speed signal processing required for rich video recording such as 4K. Integrating superior noise reduction systems, DMC-GH4 enables shooting at max.ISO25600. Sensitivity, gradation performance, resolution and color reproduction are dramatically improved to achieve even higher picture quality. The DMC-GH4 boasts high speed burst shooting at 12 fps(AFS) up to approx.40 (including RAW) / approx.100 (excluding RAW) and 7.0 fps(AFC) to capture fast moving subject just in-focus.

The new DMC-GH4 further evolves to bridge the gap of consumer video camera and professional video camera. One of the most prominent advance is unlimited*1 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4*2. The DMC-GH4 is also capable of recording Full- HD video with ultra high bitrate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) without recording time limit *1*2. Users can freely choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage. For the global business of professional users, the system frequency can be flexibly selectable between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz. The DMC-GH4 is also capable of real-time image output to the external monitor via an optional micro HDMI cable simultaneously while recording video. For more unique video expression, VFR(Variable Frame Rate) or Time Lapse/Stop Motion Animation can be produced with DMC-GH4 without postproduction process. In addition, a variety of practical functions required for professional video recording are newly integrated.

The high-precision Contrast AF system in the DMC-GH4 is further enhanced by Panasonic’s integration of DFD (Depth from Defocus) technology which even shortens the time to set focus to achieve ultra high speed AF of approx.0.07 sec*3. Not only speed but also the operability is enhanced thanks to the addition of Face / Eye Detection AF or 49-point AF with Custom Multi AF mode.

The DMC-GH4 boasts newly developed high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for 2,359K-dot LVF (Live View Finder) and 1,036K-dot rear monitor. Both LVF and rear monitor adopts OLED to achieve high speed response with minimum time lag while enhancing the resolution. Notably, the OLED for the LVF in DMC-GH4 boasts 10,000:1 high contrast for superior color reproduction. Now the excellent visibility comes closer to OVF.

To be tough enough to withstand even heavy field use, the main structure of the DMC-GH4 is composed of magnesium alloy full diecast front/rear frame. It also features splash / dustproof construction thanks to the sealing on every joint, dial, and button. The shutter unit that allows max. 1/8000 fast shutter release is also redesigned to be even more durable for approx. 200,000 times release*4.

Even a moment’s waste matters in professional shooting condition, hence it is possible to make target setting intuitively thanks to the optimum layout of control devices on DMC-GH4 . The DMC-GH4 also incorporates Wi-Fi® with NFC technology, terminals highly connectable to external equipment. Now RAW files can be developed in camera.

Evolving further in every aspect – performance, mobility, durability and expandability, Panasonic is proud to offer DMC-GH4 for a reliable first camera to professional field photographers, film creators and hybrid photographers.

1. The Newly Developed 16.05-Megapixel Digital Live MOS Sensor and Venus Engine Achieving High Speed, High Sensitivity Image Recording

Panasonic developed new 16.05-megapixel Digital Live MOS Sensor for DMC-GH4 that achieves high quality, high sensitivity image recording with quick response. Approx. 50% higher speed signal readout suppresses rolling shutter effect even when using electronic shutter or recording motion image. The maximum number of recordable images is up to 40(including RAW) / 100 (excluding RAW). Taking full advantage of the Live MOS Sensor, gradation range is expanded by max.1/3 step at low ISO end with fine tuning control by the Venus Engine. Plus, superior noise reduction realizes max.60 min long exposure in B(bulb) mode.

The image processor Venus Engine is also newly developed dramatically boosting its performance with new quad-core CPU that lets high speed signal processing required for rich video recording such as 4K. The advanced Multi-process NR (Noise Reduction) applies effective noise reduction and edge processing according to each component frequency. Plus, newly added Random Filter granulates chromatic noise to be blended into the image even more naturally. As a result, the max. ISO 25600 is achieved. On the other hand, optimizing the combination design of new sensor, new imaging engine and low-pass filter enhances the limit resolution by more than 5% while suppressing moire. Newly adopted aperture filter is capable of controlling over wider frequency range. It adjusts the amount of sharpness according to the frequency level, resulting in faithful stereoscopic effect. The Venus Engine also improves color reproduction with accurate evaluation of each color even it is similar not only in color phase but also in saturation and luminosity.

The combination of the Digital Live MOS Sensor and the Venus Engine achieves stunning picture quality in its natural way – that is what LUMIX aspires for.

2. The World’s First Digital Single Lens Mirrorless (DSLM) Camera Recording High Quality Video in 4K – To Meet Professional Quality and Standard

The predecessor DMC-GH3 created an industrial sensation with its outstanding video recording performance that meets the professionals’ quality and standard. The new DMC-GH4 further evolves to bridge the gap of consumer video camera and professional video camera. One of the most prominent advance is unlimited*1 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4*2. The DMC-GH4 is also capable of Full- HD video with ultra high bitrate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB), which does not have limit of recording time*1. Users can freely choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage [Figure#1]. In MP4 / MOV, high quality sound in LPCM (Linear Pulse Code Modulation) is recordable. For the global business of professional users, the system frequency can be flexibly selectable between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz.

The DMC-GH4 is also capable of real-time image output to the external monitor in 4:2:2 / 8-bit*3 via an optional micro HDMI cable simultaneously while recording video. Even 4:2:2 / 10-bit is available which is suitable for the professional video making that requires serious monitoring of the footage. Users can choose to output only the recording content or the content with the setting menus individually depending on a display.

Plus, the VFR( Variable Frame Rate) enables recording video with slow/fast motion such as 96 fps, 4x, all in Full-HD[Figure#2]*4. Time Lapse/ Stop Motion Animation video can be produced in camera, too.

For more precise control over video image quality, the DMC-GH4 integrates Zebra Pattern to watch white wash-out or Focus Peaking. The DMC-GH4 even allows Master Pedestal system is newly integrated with which users can adjust the brightness balance ±15 steps based on the color of black. Gamma presets exclusively for video recording are newly available in Creative Video mode – “CINELIKE D” and “CINELIKE V” for rich video expression like a cinema. Synchro Scan mode is also newly available to reduce suppress flicker. It is selectable to display Center Marker while recording.

The DMC-GH4 is equipped with functions that meets global standard for synchronous video recording. 1KHz Test Tone and Color Bars(SMPTE / EBU / ARIB Standard) are newly available on DMC-GH4. The DMC-GH4 also embeds SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods, which makes it easy to synchronize the multiple video footage or sound source in the post production workflow. Time Code Value can be started at any point of [Reset], [Manual Input] and [Current Time]. Drop frame or Non Drop Frame time code is selectable*5.  When recording the video in MOV, AVCHD Progressive, AVCHD or MP4(LPCM), the DMC-GH4 automatically generates multiple seamless files for continuous recording. During playback, the AVCHD Progressive / AVCHD files are reproduced with seamless, interruption-free continuity.

A total of 22 LUMIX G digital interchangeable lenses offers any creative perspective according to the scene. Especially those crowned as HD lenses allows silent, high performance AF control suitable for video recording.

3. High Speed Response Required for Professionals and Practical AF Options

All cameras of LUMIX G adopt Contrast AF for its focus system. Compared with the Phase difference system AF, the Contrast AF boasts higher accuracy especially in shooting with bright lens with small F value. With the LUMIX G digital interchangeable lens capable of digital signal exchange at max. 240 fps, the focusing is stunningly quick and smooth. The Contrast AF system in the DMC-GH4 is further enhanced by Panasonic’s integration of DFD (Depth from Defocus) technology which even shortens the time to set focus. It figures out the distance to the subject by evaluating 2 images with different depth of field while consulting the data of optical characteristics of the using lens in a moment. As a result, the DMC-GH4 achieves ultra high speed AF of approx.0.07 sec*. This improvement benefits more as focusing distance increases. The speed of burst shooting is dramatically faster than the predecessor DMC-GH3, boasting high speed burst shooting at 12 fps (AFS) up to approx.40 (including RAW) / approx.100 (excluding RAW) and 7.0 fps (AFC) to capture fast moving subject just in-focus.

Not only these, stability of continuous focusing is improved focusing is now even smoother by minimizing wobbling in both photo and video recording. Together with the quick start-up and short release time lag, the DMC-GH4 never lets photographers miss fleeting shooting opportunities.

In addition to the conventional Face Recognition AF, the DMC-GH4 newly incorporates Eye Detection AF which automatically sets focus right on the eye of human face. Focus point is increased from 23 (DMC-GH3) to 49 points for more flexible composition together with Custom Multi AF mode in which users can freely select the blocks to focus out of the 49 focusing area. Now the 1-area AF area can be seamlessly magnified not only in manual but also in auto focus mode. Tracking AF is also advanced in the point of tracking accuracy by estimating the subject’s movement.

Focus point can be set on any part of the 100% field of view. The time to show magnified image can be selectable in Pin-point AF. Focus point can be magnified either with MF ring or with cursor key in MF Assist mode. In the Touch Pad AF, the position can be set either on absolute/relative coordinate. Together with the Eye Sensor AF which starts focusing by just looking into the viewfinder, the AF/AE lock button works for AF for quick auto focusing even when using LVF.

* In AFS, With LUMIX G VARIO 14-140mm / F3.5-5.6 ASPH. / POWER O.I.S. or LUMIX G X VARIO 12-35mm / F2.8 ASPH. / POWER O.I.S.

4. Stunning Mobility Supported by Mechanical Advancements

The DMC-GH4 boasts newly developed high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for LVF (Live View Finder) and rear monitor. Increasing the resolution of display area to 2,359K-dot, the new 16:9 Wide Screen LVF boasts approx.1.34x / 0.67x (35mm camera equiv.) magnification and 100% field of view and eyepoint of approximately 21 mm. Thanks to the newly designed large eyecup, the visibility of LVF is dramatically improved. The image output between the LVF and the rear monitor is switched automatically with the eye sensor on the LVF, which features options of sensitivity – high, low and off – to reduce false operation during touching on the rear monitor. The 3.0-inch 1,036K-dot free-angle OLED rear monitor (3:2 aspect) with wide-viewing angle rotates 180° to the side and tilts 270° up and down offers approx. 100% of field of view. This rear monitor adopts static touch control for more smooth operation either in shooting or in playback. Both LVF and rear monitor adopts OLED to achieve high speed response with minimum time lag while enhancing the resolution. Notably, the OLED for the LVF in DMC-GH4 boasts 10,000:1 high contrast for superior color reproduction. Now the excellent visibility comes closer to OVF. On the other hand, live view image can be displayed in monochrome through LVF which enables shooting concentrating on contrast.

Even a moment’s waste matters in professional shooting condition but it is possible to make target setting intuitively with DMC-GH4. The 3 dials are equipped on the top and back of the camera and the main dial is now comes with lock structure. A dedicated button allows direct reach to exposure compensation, white balance adjustment or ISO setting and max.5 settings can be assigned to the Fn button. All these external components are designed to be operated easily without taking eyes off through the viewfinder.

To be tough enough to withstand even heavy field use, the main structure of the DMC-GH4 is composed of magnesium alloy full diecast front/rear frame. It also features splash / dustproof construction thanks to the sealing onto every joint, dial, and button. The shutter unit is also redesigned to be even more durable for approx. 200,000 times release*. It offers highest shutter speed at max. 1/8000 not only to capture spur-of-the-moment of fast moving subject but also to use high-speed lens with open aperture even in outdoors to give impressive defocus. Both built-in/external flash can be synchronized with max.1/250 second shutter speed*2.

With Panasonic “Image App”, remote shooting of both photo and video* is available by using the smartphone/tablet for a remote shutter with a monitor. Not only releasing a shutter, zooming, focusing and settings of shutter speed, aperture, exposure compensation are all controllable with a smartphone / tablet. All these flexible shooting / browsing / sharing style are made possible with the DMC-GH4 and the Panasonic’s dedicated application software Panasonic Image App for iOS / Android smartphones / tablets. It is also easy to embed geotag in the image after shooting. For the smartphone/tablet without NFC, the camera displays dedicated QR code on its monitor to complete pairing easily by reading the code.

 

Output/Input Terminals

The DMC-GH4 comes with a variety of connection terminals for more flexible shooting options. The 3.5mm microphone jack is for high quality audio recording using an external microphone and the 3.5mm headphone jack which enables monitoring the recording audio while shooting video real-time. It is also capable of real-time image output on the external monitor via an optional HDMI micro cable simultaneously while recording video. In addition to these, the DMC-GH4 complies with AV outputs (Audio 2ch, Composite), flash sync terminal and 2.5mm jack for remote controller.

For reliable recording of rich video, the DMC-GH4 complies with UHS Speed Class 3 (U3) which is the new speed class standard of SD memory card. The UHS Speed Class 3 (U3) guarantees a constant minimum write speed of 30MB/s to respond to market needs for 4K video.

 

Optional Accessories

A GN58 powerful External Flash (DMW-FL580L) is newly added to the LUMIX G optional accessories which allows high speed charging of approx.1.7 sec. Not only wireless control but also LED video light function are available. The Stereo / Shotgun Microphone (DMW-MS2) which enables stereo/shotgun switch even allows more precise sound recording with selectable Super Shotgun / Lens Auto / Manual option on DMC-GH4.

6. Other Features
