  • @DrDave

    As it will be based on same LSI as old cameras - it will overheat.

    Again - camera companies have two problems now. LSI development and manufacturing costs and software development costs.

    In normal situation cameras had been long ago using standard OS and situation on LSI front must be same as with sensors.

    Problem is - top managements resist such changes as understand that next step will be obliteration of proprietary lens mounts. And companies like Foxconn will enter this market niche and wipe out all Japanese old times.

    Situation is similar in TV market where mass manufacturers now live on spying on customers, stealing private data and selling it. So, they can not allow standard OS, like Android TV that is times better than horrible Samsung andLG things.

    SAN DIEGO --- Jan. 15, 2019 --- Sony Electronics Inc. today introduced an exciting new addition to its E-mount mirrorless camera lineup -- the α6400 (model ILCE-6400).

    The α6400 brings many of Sony's most advanced technologies from their acclaimed full-frame lineup to a compact, lightweight APS-C camera. The speedy new camera boasts the world's fastest1 autofocus (AF) acquisition of 0.02 seconds, while also introducing the new advanced "Real-time Eye AF" and "Real-time Tracking" capabilities. Also included are high-speed shooting at up to 11 fps with AF/AE tracking, a new-generation BIONZ X image processing engine that produces excellent image quality, 4K video recording, a fully 180-degree tiltable LCD touch screen and much more, making it the ultimate tool for all types of creators ranging from professionals to vloggers.

    "The α6400 represents another important step in the growth of Sony's overall interchangeable lens camera lineup," said Neal Manowitz, vice president of Imaging Solutions at Sony Electronics. "By bringing so many of our latest and most advanced technologies from full-frame cameras to a brand new APS-C model, we are giving today's creators more options than ever to realize their vision."

    Seedy Performance that Captures Decisive Moments

    The impressive autofocus system on the new α6400 inherits many technologies from Sony's newest line-up of full-frame cameras including the α9, α7R III and α7 III models. The new a6400 features 425 phase-detection AF points and 425 contrast-detection AF points that are placed densely over the entire image area, covering approximately 84% of the image area. This high-speed, high-performance tracking AF system is paired with a new-generation BIONZ X image processing engine that together allow the camera to acquire focus in as little as 0.02 seconds and maintain subject lock extremely effectively, ensuring even the fastest moving subjects can be tracked and captured with ease.

    The α6400 introduces advanced "Real-time Eye AF," the latest version of Sony's acclaimed Eye AF technology. This exciting new capability employs artificial intelligence based object recognition to detect and process eye data in real time, resulting in improved accuracy, speed and tracking performance of Eye AF. In all autofocus modes, the camera now automatically detects the eyes of the subject and activates Eye AF with a half press of the shutter button, and when in AF-C or AF-A mode, the preferred eye (left or right) of your subject can be selected as the focus point. Choices include Auto / Right Eye / Left Eye, and a Switch Right / Left Eye function is able to be assigned to a custom function as well. This exciting new technology completely frees the photographer to focus solely on composition with full trust that focus will be tack sharp on the subject's eye. Eye AF support for animals will be added in summer 2019 via a system software update, ideal for wildlife photographers.

    Also debuting on the α6400 is Sony's newly developed "Real-time Tracking." This mode utilizes Sony's latest algorithm including artificial intelligence (AI) based object recognition and processes color, subject distance (depth), pattern (brightness) as spatial information to ensure that all subjects can be captured with excellent accuracy. Additionally, when photographing or videographing humans or animals, face and eye position information is recognized by AI and the subject's eye7 is monitored in real time with extremely high tracking precision. This can be activated by a simple half press of the shutter button, or can be assigned to a custom function as well.

    In terms of overall shooting speeds, the new camera can shoot at up to 11 fps4 with full AF/AE tracking while utilizing the mechanical shutter, and up to 8 fps5 with full AF/AE tracking while silent shooting. It can shoot at each of these speeds for up to 116 frames JPEG Standard / 46 frames RAW compressed, greatly increasing the chances of capturing the perfect moment.

    All-around Advancements in Image Quality

    Sony's new α6400 is equipped with a 24.2 MP APS-C sized image sensor with that is paired with an upgraded BIONZ X processor to deliver incredible advancements in image quality and color reproduction in all types of shooting conditions. Standard ISO ranges up to ISO 32000 for both still and movie, and is expandable up to ISO 102400 for still images, with excellent noise reduction at medium and high sensitivities.

    The camera also inherits many of the image processing algorithms from Sony's newest full-frame cameras, greatly suppressing noise while preserving resolution and improving texture depiction.

    Advanced High-Resolution 4K Movie Recording with Fast Hybrid Autofocus

    The versatile α6400 is an exceptional video camera, offering internal 4K (QFHD: 3840 x 2160) movie recording with full pixel readout and no pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth. Focusing during movie shooting is fast and stable thanks to upgraded Fast Hybrid AF technology, which keeps the subject in constant smooth focus no matter the scene, and even if an object crosses in front of the camera. This advanced AF plus touch focus functionality make it an ideal camera choice for many vloggers and video creators that are regularly creating and uploading content online.

    For time-lapse movie creation, the new camera features built-in interval recording that can be set anywhere between 1 and 60 seconds, with a total number of shots from 1 to 9999. AE tracking sensitivity can be adjusted to "High", "Mid" or "Low" during interval shooting, allowing for reduced changes in exposure over the shooting interval.

    Additionally, for the first time in Sony APS-C mirrorless camera, the new model includes an HLG (Hybrid Log-Gamma) picture profile, which supports an Instant HDR workflow, allowing HDR (HLG) compatible TV's to playback beautiful, true-to-life 4K HDR imagery. Further, both S-Log2 and S-Log3 are available for increased color grading flexibility, as well as Zebra functionality, Gamma Display assist and proxy recording. The camera can also record Full HD at 120 fps at up to 100 Mbps, allowing footage to be reviewed and eventually edited into 4x or 5x slow-motion video files in Full HD resolution with AF tracking.

    Upgraded Build to Maximize Versatility

    The new camera is designed to offer a high level of functionality and customization to maximize shooting freedom. New on the α6400 is a fully 180-degree tiltable, 3.0-type LCD flip screen with 921k-dots of resolution that allows for simple and effective framing of selfie-style shooting for both still and video capture. Utilizing this capability, vloggers will be able to check and monitor composition throughout their entire creative process. The LCD screen is also equipped with touch functionality, with options for Touch Pad, Touch Focus, Touch Shutter and new Touch Tracking which quickly activates "Real-time Tracking" through the touch screen.

    The camera features a high quality XGA OLED Tru-finder™ viewfinder, extensive customization with 89 functions that are assignable to 8 custom keys, the new My Dial and My Menu functionality, enhanced overall menu usability, a help screen for menus, star rating for images, and many other features that allow for a seamless shooting experience. It is also built with a tough magnesium alloy design and has an extremely durable shutter that is rated for approximately 200,000 cycles. It also is capable of seamlessly transferring files to a smartphone or tablet when connected to the brand new Imaging Edge Mobile application.

    Pricing and Availability

    The α6400 will ship in February 2019 for a suggested retail price of $900 USD and $1,250 CAD. It will also be offered as a kit with the 16-50mm F3.5 -- 5.6 lens for a suggested retail price of $1,000 USD and $1,350 CAD, or in a kit with the 18-135mm F3.5 -- 5.6 lens for a suggested retail price of $1,300 USD and $1,750 CAD.

  • Announcement recording

  • The rolling shutter looks bad, Check out this video between 3:16 to 3:21

  • Sweet - a camera released for vlogging without IBIS and with the same nasty rolling shutter that has plagued the A6x00 line.

  • Well, it is camera made by marketers who saw small niche and plugged their camera in it.

    otherwise add a little and get a6500 if you want E mount

  • There is no record time limit. But with no IBIS, dumb tilty screen, sick rolling shutter, no headphone jack, poor battery life and dearth of APS-C glass, can't see why anyone would want this for filmmaking or vlogging.

  • Flippy screen blocked by mic, lol

  • @jonpais no record time limit? RU sure? Awesome news if true.

  • This may not be the camera for most of the people that are seriously into video/photography. However for an entry level camera at this price point it is hard to beat. Slap on the Sigma 16mm/56mm 1.4 and call it a day... you will have a tiny little package that can do just about anything. The other thing to consider is demographics in terms of who will purchase this type of camera and also the fact that once they are in the "Sony" ecosystem there is a good chance that they will stay and or upgrade to the Sony R series of cameras and lenses. And we all know how that goes... Camera systems are kinda like the Mafia... once you are in you are in and cannot get out LOL

    I will say this if my son or somebody I knew asked me today which camera system they should invest in from scratch I would be very very hard pressed not to recommend Sony. Sony is kicking some serious ass right now and the millennials are flocking to the Sony cameras. This is brilliant move on Sony's part.

  • Utterly disappointed by Sony, as this "could have been" a great handheld vlogging compact camera with the Sony 20mm pancake, but with no IBIS?? Might as well get the Panasonic G85 instead

    1920 x 1080 @ 30p / 16 Mbps, MOV, H.264, Linear PCM

    Why is 1080 so crippled?

    Hoping it will not overheat and have no record time limit, but I am ready to be disappointed.

    I'll eat my hat if this camera doesn't overheat at some point.

  • @DrDave Yes, no more video record limit. Of course, it will still overheat and batteries will die.

  • @jonpais Yes, I suppose the time limit is meaningless if it burns to the ground or melts into a ball of slag. Has anyone left it on to see how hot it gets? I use USB to 8.4v steppers so not worried about the battery, the battery is the backup.

  • In-depth review by Max. He would choose a6400 over a6500. New processor means even with the old style battery, he was getting 1-1/2 hours and no overheating. Also, at the event, Sony responds to Nikon, saying e mount could do f/.63 (not that I ever cared - f/1.4 is more than enough for me). Some explanation and samples of how well real-time tracking works.

    Think yourself, do not listen to Max or anyone else. Max lives from convincing you to buy camera, if he'll be bad at this he will have nothing to eat.

    For general user a6500 is better camera usually. But it all depends on actual needs. I suggest to wait few months as camera most probably soon slide around $200 lower.

    Also, at the event, Sony responds to Nikon, saying e mount could do f/.63 (not that I ever cared - f/1.4 is more than enough for me).

    They told this even back at Photokina time.
