DJI PHANTOM 4 Pro Camera/Video 4K Review

DJI PHANTOM 4 Pro Camera

 Dji Phantom series is one the famous drones in world. As you know, Dji Phantom has a perfect specification with a good price. The last drone of Phantom series is Phantom 4 Pro. You can read the review "Here".

 Now, we will do a complete review for camera of Dji Phantom 4 pro.

CAMERA WITH 1-INCH 20MP SENSOR

 The onboard camera has been redesigned to use a 1-inch 20-megapixel CMOS sensor. A custom engineered lens made up of eight elements is arranged in seven groups, it is the first DJI camera to use a mechanical shutter, eliminating rolling shutter distortion which can occur when taking

images of fast moving subjects or when flying at high speed. In effect, it is as powerful as many traditional ground cameras.



 More powerful video processing supports H.264 4K videos at 60fps or H.265 4K at 30fps, both with a 100Mbps bitrate. Advanced sensors and processors ensure everything is captured with more image detail and the image data needed for a
dvanced post-production.

 Operating range is very strong. In a rural environment I flew the drone 4,250 feet away from my position before getting any sort of choppiness in the live video feed, at which point I turned it around and brought it home.


 In a suburban setting, crowded with homes and Wi-Fi signals, the Phantom flew 2,600 feet away from the launch point before the video signal became spotty. Both figures are in line with our Phantom 4 tests—it flew 4,500 feet in a rural test spot and 1,800 feet in suburbia before the video signal began to cut out.

 The only drone that's done better in our rural test is DJI's tiny Mavic Pro, which flew a full mile away from launch without a stutter—I didn't try to fly it any further than that.

HIGH RESOLUTION LENS

DJI PHANTOM 4 Pro Camera

The resolution and contrast of a lens is critical to image quality, because only a quality lens can capture sharp, vivid photos at high resolutions. Thebrand new Phantom 4 Pro camera has an aerial optimized F2.8 wide-angle lens with a 24mm equivalent focal length. It features eight elements – 2aspherical – arranged in seven groups that fit into a smaller, more compact frame.



 Its images are consistently detailed with low distortion and lowdispersion, ensuring that photos and videos are sharp and vivid. For the first time ever with a DJI camera, MTF (Modulation Transfer Function)results have been made public, so people can get a better understanding of lens performance.


* An MTF chart is used to measure the ability of a lens to reproduce contrast and resolve details. Low spatial frequencies reflect overall contrast, and high spatial frequencies reflect detail resolution. Both are measured in lp/mm. Image Height indicates the distance of a given point on the lens from the center of the sensor. MTF 100% indicates perfect performance.

 A mechanical shutter with a max speed of 1/2000s eliminates rolling shutter distortion which can occur
when taking images of fast moving subjects or when flying at high speed. The electronic shutter has also been improved with a max shutter speed of 1/8000 seconds, and a new Burst Mode shoot capable of shooting 14 fps at 20 megapixels to catch the perfect moment.

PRODUCTION OPTIMIZED 4K

 An enhanced video processing system allows video to be captured in cinema and production optimized DCI 4K/60 (4096 x 2160/60fps) at a bitrate of 100Mbps, enabling you to get high-resolution slow motion shots.



 The Phantom 4 Pro also supports the H.265 video codec (Maximum resolution 4096X2160/30fps). For a given bitrate, H.265 doubles the amount of image processing as H.264, resulting in significantly enhanced image quality.

Record in the high dynamic range D-log mode to make the most of this image data for color grading.



 When it comes to shooting video, the P4 Pro offers a litany of options. You can shoot in cinematic 4K DCI at 24, 25, or 30 frames per second, or 4K UHD at 24, 25, 30, or 60 frames per second. If that’s too much for your eyeballs (or SD card) to handle, you can also scale down to 2.7K, 1080p, and 720p — the latter of which can be captured at 120 frames per second and used to create slow-mo footage.

  1. A really nice review of the camera and its features. Thanks for this, I had no idea that they improved it so much. I also found a review of the P4 drone, and I can say that I learned a few new things about the P4 and hope you will find it interesting and useful as I did.
