While looking at the recently published spec comparison at our website many of our users are sending few common questions to us, it includes; How Panasonic is able to do AF in just 0.07 sec with the help of contrast based technology? Does DFD technology is actually a firmware or hardware thing ? Where does the Panasonic DFD Actually placed, inside the sensor or somewhere else ?
I want to keep this post as short as possible
What is DFD?
Panasonic DFD is hardware and exclusively designed & developed by Panasonic and it’s not a software. DFD autofocus relies on special hardware in the camera’s processor, so can’t be brought to older models via firmware updates.
How it Work?
Before we explain that we have to understand how the traditional contrast based system work, the traditional contrast detect system based camera actually. Camera having a normal contrast based Sensor determines the best focus point by moving the AF ring and scanning the entire subject, once the scan is done the lens AF reverse back to peak focus point. However when a Panasonic camera uses DFD technology, it quickly predict aka calculate the AF point and move AF point quickly there, finally it uses contrast based system to fine-tune the AF point.
So don’t get confused that Panasonic newly announced camera is using contrast based system only, the Camera AF based on DFD tech and later it fine-tuned by contrast AF. The biggest advantage of this technology that sensor doesn’t have any single dead pixel like other Hybrid AF sensors have for phase AF.
Before the announcement of Panasonic GX8 camera there were no options to the users to go beyond the 16 megapixels limit for Micro Four Thirds (MFT) sensors. Its 5-axis Image stabilization system is designed in such a manner that it will work in two way, it sync with Lens based IS system and hence you get Dual IS system based camera that combat camera shake very effectively.
Hence, after showing its incredible features of all the sections we can undoubtedly think it as one of the unique product of Panasonic.
The most important feature of the camera is dual IS system, The GX8 features built-in 5 axis Image stabilization system as well it also supports lens based IS of Lumix O.I.S lenses. Both system work very effectively with each other and gives excellent result when used in adverse situation.
Panasonic DFD Technology, the Panasonic DFD technology (Depth-From-Defocus) is added in the system camera to calculate the distance of the subject and adjust its focus quickly, as fast as 0.07 seconds. With the help of DFD technology the camera can shoot 6 frames per second with full time Auto-focus support. Additionally, supporting working in low-light conditions, a Starlight AF feature enables accurate AF performance down to -4 EV.
4K Still image mode; The Panasonic GX8 is capable to capture 8MP of still images @ 30fps, it’s more than enough for a sports shooter. The biggest advantage GX8 is you can record 8 MP of still images upto 30min.
Panasonic GX8 can captures 4K video at 30 frames per second and 24 frames per second at 100 Mbps in MP4 format. The camera Can also record Full HD videos @ 1080p/60, both formats are available for Full HD video mode, MP4 and AVCHD.
1/16,000 sec of electronic and 1/8000 of mechanical shutter speed. The GX8 camera can touch its shutter speed upto 1/16,000 sec. to better enable working in bright conditions and with wider aperture settings.
These above mentioned features are class leading and make GX8 a prefect choice for mirrorless shooter.
The recently announced Panasonic GX8 camera , the camera features newly developed sensor and world first camera to feature DUAL IS system, the camera features built-in image 5-axis stabilization system and also utilizes the lens IS correction mechanism.
Take a look at the sample videos captured with Panasonic GX8, the first video 4K video is captured with a pre-production camera and the next one is uploaded by Panasonic itself,
Daniel Berehulak, a world-renowned award-winning photojournalist, travelled to Cuba with new LUMIX DMC-GX8 to document an evolving culture and society going through significant social, political and economic change. This is a part of his journey recorded with GX8 in 4K.
You can also enjoy photos shot by him and the behind-the-scenes with shooting impression of GX8.
In a statement issued by the Panasonic USA today, Panasonic said that user’s facing rubbed-off serial number problem isn’t a major issue, they should keep the label of the camera Box of that states the serial number of your G7 camera, and even if your serial number is completely wiped-off then there is no issue, your camera warranties will remain valid. You can register your product at Panasonic prodregister website to avoid any negative impact on the camera’s warranty.
Take a look at the press release
Panasonic has just become aware that some customers who recently purchased DMC-G7s are experiencing rubbed-off printing of the camera’s serial number tag and we apologize for any concern this may have caused. Any reference that these are “knockoff” cameras is not factual. We have already informed our factory in Japan who is investigating these reports. Be assured that this will not have any negative impact on the camera’s warranty. Your warranty is validated by the proof of purchase from an official retailer and the serial number clearly appears on the carton’s UPC label. All customers should retain these two documents in addition to registering your camera on the Panasonic web site in the unlikely event that you require service.https://secure2.prodregister.com/pnaportal/index.aspx
As we have published earlier that the Wi-Fi ALLIANCE has leaked out the name of upcoming Panasonic cameras, the list includes the name of Panasonic G7, GX8 and FZ300 camera. Out of all these three camera only Panasonic G7 was announced few days ago.
At this moment we are still not clear about the specification and announcement date of the two camera., but we do hope that the Panasonic GX8 will get a new sensor and FZ300 will also come with some incremental update.
Both the camera is rumored to arrive in July 2015.
During the Panasonic G7 announcement Panasonic revealed its future plans of 8K video, including 4K at 60fps and 120fps, take a look at a snapshot what ephotozine writes
“Panasonic announced plans for future 4K and 8K video and photo features, including 4K at 60fps and 120fps, as well as the ability to take 33 megapixel still images from 8K video footage. They say they are planning to have this technology ready for the Tokyo 2020 Olympic games. No further information was given at the time.“
If the camera records 8K video that also means you can capture 33 megapixel still images from 8K video footage. I personally don’t believe the upcoming GH5 will carry 8K tag.. since Panasonic said that they are planning to have this technology ready for the Tokyo 2020 Olympic games… that clearly means upcoming Panasonic GH6 or GH7 will have 8K video recording.
Now let’s talk about some fiction
Our staff team member Joy created a neat list based in the pattern of camera announcement from Panasonic …
Panasonic G7 is one of the most affordable camera that captures 4K video and records internally, Take a look at the sample images of recently announced Panasonic G7 camera, here is the announcement page with press release,
