Davide DB 412 Posted February 5, 2014 (edited) At Las Vegas's CES Panasonic displayed an upcoming GH-4K. (Actually it was just a GH3 with a 4K sticker). Nobody knows if the new model will have the same GH3 body or not... Rumors sites write that it will be launched officially on 7th February. So just this friday Anyway these are the rumored specs until now: High speed 16Mp sensor 2.36Mp OLED EVF peaking 4K 200Mbps mode 1080p120 422 recording Panasonic announced also a new SD card expressely made to cope with 4K: A second round of rumors add few more specs: There is an attachable XLR adapter H264 codec all intra that give 422 color all intra in 100 mbps. it will be switch-able from 4K and 1080P with various frame rates (can shoot 120fps at 1080P for example) Last but not the least: price less than 2000USD Someone suggested that the new camera will use the new LSI developed from Pana with its codec AVC-ULTRA: http://pro-av.panasonic.net/en/sales_o/p2/AVC-ULTRA_obverview_rev1.0.pdf AVC-ULTRA Overview, rev 1.0 Expanding business opportunities with unified codecPanasonic has developed a new LSI codec engine to perform a variety of encoding/decoding processes defined in the AVC-ULTRA codec. Figure 12 shows the appearance of the LSI and the photo of the LSI chip. The codec engine supports H.264/AVC profiles for professional applications, “CAVLC 4:4:4 Intra”, “High 4:2:2 Intra”, “High 10 Intra”, and “High 4:2:2”, up to Level 5.2 for 4K. This codec engine also has the ability to encode/decode the conventional DVCPRO codec family as well as the newly developed AVC-ULTRA. Incorporating the codec processor chip and high speed memory chips all within a single small package increases reliability and greatly reduces power consumption..This new codec engine unifies AVC-Intra, AVC-LongG and AVC-Proxy and also supports from HD to 4K formats. An AVC-ULTRA product implementing this engine can support many formats and can be expanded by upgrading. Users can select optimum video formats and codec schemes depending on their target applications, workflow, and estimated budgets for production and it expands their business opportunity with minimum investments. Will see in few days what's true on this little monster. Via http://www.43rumors.com/?s=GH4k Edited February 5, 2014 by Davide DB Share this post Link to post Share on other sites
Davide DB 412 Posted February 5, 2014 These are the new SD cards for 4K/2K content allegedly used on the new camera. Kingston just jumped on the bandvagon today http://www.techpowerup.com/mobile/197552/kingston-digital-introduces-sdhc-sdxc-uhs-i-speed-class-3-u3-memory-cards.html Kingston Digital, Inc., the Flash memory affiliate of Kingston Technology Company, Inc., the independent world leader in memory products, today announced its fastest addition to the Secure Digital product line. The new DHC/SDXC UHS-I Speed Class 3 (U3) card (Kingston part #: SDA3/xxGB) allows professionals and consumers to capture 4K and other Ultra-HD video resolutions. The new card is available in 16 GB, 32 GB, and 64 GB capacities. The SD Association's latest specification, UHS-I U3 (Ultra High-Speed Bus, Speed Class 3), guarantees performance of at least 30 MB/s read and write, enough bandwidth to record and playback 4K video without interruption. Kingston's SDHC/SDXC UHS-I Speed Class 3 card provides speeds of 90 MB/s read and 80 MB/s write, which is up to 9x faster (read) and up to 8x faster (write) than standard Class 10 SD cards. The faster speeds ensure the best video and photo integrity by reducing stutter as well as faster PC upload time especially when using USB 3.0 card readers Share this post Link to post Share on other sites

kc_moses 142 Posted February 6, 2014 The replacement for Canon 7D is also rumored to be announce this Friday. Not sure if Canon would suprise everyone with a 4K capable prosumer sLR because at point in time, spending thousands of dollar for a 1080p capable only camera is just no point.

thetrickster 328 Posted February 6, 2014 (edited) Defintely photos of a different camera.... Good news for us. using some photoshop and some GH3 images, it appears exactly the same body and button configuration (YAY NA-GH3 will fit!) Only difference I can see is the eye cup and the mode dial - looks a tiny bit taller (but could be the angle of the photo) Edited February 6, 2014 by thetrickster 1 Share this post Link to post Share on other sites

thetrickster 328 Posted February 6, 2014 (edited) You know.... there is one BIG difference - I've just seen... There is a button inside the top of the control dial and difference markings.... Perhaps you have to engage/press that top button to unlock the control dial? Edited February 6, 2014 by thetrickster 1 Share this post Link to post Share on other sites

thetrickster 328 Posted February 7, 2014 That extra 2mm - maybe from the new eyecup design. Now this camera has been in peoples hands - i do wonder if anyone has actually tried to stick it in a NA-GH3 housing..... Size-wise, button-wise and shape-wise its all a massive goer for a 'cheap' upgrade from the GH3, using all your existing housings etc - but that locking control dial is a) slightly taller b) not usable unless you can engage the middle button. I suppose from a keep it cheap idea, just stuck it in M mode and be done with it Preordered already - 10bit 4:2:2 - OH YES PLEASE!!!!

The lock button should have no impact, just make sure it is not depressed before you put in housing so you can then rotate mode dial while in housing. Looking good for stills 1/250 flash sync,better dynamic range, faster focus,focus peaking. Looking great for video. Hopefully as the body is very similar Nauticam can quickly develop a new housing with the vacuum leak detector. I will be upgrading from my GH2. Share this post Link to post Share on other sites

thetrickster 328 Posted February 7, 2014 RE the lock button - haven't seen it in action from any video yet - but do you need to depress it while turning (like my old Olympus E-1) or are you thinking its lockable..? I think Nauticam don't need to do a 'new' housing.. this thing I'm sure will fit the NA-GH3 ....I have the vacuum leak detector in my NA-GH3 The lock button should have no impact, just make sure it is not depressed before you put in housing so you can then rotate mode dial while in housing. Looking good for stills 1/250 flash sync,better dynamic range, faster focus,focus peaking. Looking great for video.

Kevster 6 Posted February 7, 2014 To get the most from the video i assume an Atomos Ninja will be required, to record 10 bit 4:2:2. Looks like this will be an expensive upgrade Share this post Link to post Share on other sites
Davide DB 412 Posted February 7, 2014 To get the most from the video i assume an Atomos Ninja will be required, to record 10 bit 4:2:2.

thetrickster 328 Posted February 7, 2014 I have an Ninja2 with the NA-NINJA2 housing - so this for me - is getting better and better To get 10bit 4:2:2 - it will only go to external recorder - so no recording on camera at the same time - lets hope they haven't forgotten about power saving issues (and it going to sleep while not recording!!) Davide - yes it does have amazing on camera recording - truly epic!! but still 8bit 4:2:0. Share this post Link to post Share on other sites
