History DJI started ten years ago. During this time, the Chinese manufacturer has not only become a trendsetter in the market of flying cameras and partner Hasselblad, but also seriously declared itself in the segment of professional hangers for stabilizing video recording and manual stabilizers for smartphones and compact cameras. Quadrocopters DJI Mavic Pro review begins another line of DJI products. She replaces the successful Phantom and not on the step below the price hierarchy. But first things first.
DESIGN
The main difference from other DJI Mavic Pro review presented at quadrocopters market – foldable design that allows you to carry it in a small bag. All four of the beam with the motors are hidden in the recesses housing, turning around 180º in different planes.
In the stowed position, the rays are held due to the peculiarities of hinges, no tools for assembly is not required, the process of translation into flight position takes just a few seconds.
Dimensions in the stowed position – 83h83h198 mm in the photo he seems larger than it actually is. Take-off weight – 743 grams.
From the other products DJI Mavic Pro review differs chopped aggressive design, resembling a military objects created for stealth technology. Grey body color reinforces this impression.
The battery compartment is installed on the upper side of the casing. On battery power button is the entire device, the same key is used to approximate charge level (four LEDs).
Capacity 3830 mAh, from regular mains charger new battery is charged for about an hour by car, delivered in an expanded set – about two. Voltage – 11.4 V, the cell made by lithium-polymer technology, energy consumption – 43.6 W / h.
The battery weight (with housing and electronics) – 240 g The maximum power reserve according to the manufacturer – 8 kilometers, but it is measured in ideal conditions, with no wind.
Ahead are two obstacles to the detection chamber. Their angle of about 60º from the ceiling in the middle, working distance – from 70 cm to 15 meters, and an obstacle in the framework of an early warning system, they are able to distinguish at a distance of 30 meters.
Under removable transparent plastic cap is three-axis stabilized suspension photo-video camera. Although the cap easily removable, experts recommend to fly with him. The reason – the camera is very small and light, a gust of wind able to disrupt the process of stabilization and electronics simply lock motors suspension for a few seconds to avoid breakage.
On the side faces of the housing are located slot for Micro SD card (supports up to 64GB), and a control system switch – remote control (with and without a smartphone) or only smartphone via Wi-Fi.
On the bottom side of the casing, which is part-and the heat sink, and a kind of protective cover, there are a couple of cameras and two sonar systems to prevent collisions.
On the rear side of the casing – large LED display that tells the pilot to change colors and flashes on the status of the drone and potential problems with it.
Propellers folding, so shoot them during transportation is not necessary.
Anterior rays during takeoff and landing are based on the sloping legs, which are a hidden antenna.
The remote control is equipped with its own built-in battery (2970 mAh) and character-graphic display. The holder is installed smart phone, although you can fly without it.
To console smartphone connected short cable, supplied three of them – Lightning, Micro USB and USB Type-C. When the smartphone from the remote battery is not recharged, so care should be taken before, taking its maximum charge.
Sliding mounting system allows you to work with models with a thickness of 6.5 to 8.5 mm, most of covers (except the thinnest) have to take. The maximum length of the smartphone can be up to 160 mm.
DJI Mavic Pro The remote has a normal USB-connector. It is useful in at least two cases. Firstly, if the connector on your smartphone “reverse” in terms of the DJI, or is not on the short side of his body, while the USB-cable corresponding smart phone can still connect to the console.
Secondly, on the DJI Mavic Pro review easy to fly with the tablet, which is, of course, does not fit in the holder, but the desire to get a large screen is capable of performing miracles of engineering at the knees.
Two stick – the main element of control. In addition to them on the console has a few hardware buttons c and given varying functionalities and a pair of wheels and a five-way mini joystick. On the side face of the body is the flight mode switch – normal and sport.
WHAT IS INSIDE
DJI Mavic Pro review Electronics is mainly collected in the “mother” board, while in the line of Phantom uses modular design. From the point of view of reliability is better, but worse maintainability, since the replacement of one unit is cheaper.
The bottom cover is removed. It is a solid radiator with openings for sensors and cameras coated plastic panel. Main circuit closed individual radiators for better heat dissipation. During the flight electronics heats up considerably (even when cold) so used and thermal paste. By the way, inside a fan, its fragments visible in other images.
DJI Mavic Pro review On the larger fragment is clearly visible high quality and tight installation. Bottom – obstacle detection system of the camera, then – a couple of sonar. The camera operates at distances from 30 cm to 13 meters at a speed of up to 36 km / h.
When the top cover is removed, opens the access to the power of the board. The cables leading to the motor, rather thick, carefully soldered, the connection to the board is further reinforced by melting.
DJI Mavic Pro review It Ocusync module responsible for two-way communication between the drone and the remote control. It provides transmission of video 720p at a distance of seven kilometers (provided there is no interference and obstacles).
Electronics control the camera suspension is mounted as a separate unit. The camera rotates in the vertical plane at angles up to 90º to 30º down and up. movement speed is set in the application. If you want to take a photo in a vertical orientation, the suspension turns the camera at 90º with respect to the optical axis of the lens.
DJI Mavic Pro review Also, a separate block is made the receiver of signals of satellite global positioning systems. Mavic Pro works with two – GPS and “GLONASS”.

FUNCTIONALITY
Large scale quadrocopters DJI known primarily as a flying photo-video camera. Yes, they have a sport mode, but it’s not racing drones. Mavic Pro, despite its aggressive design, the family inherited the best features and is a great tool for those who want not only to see how the world looks from the height, but also endeavor to share with others the results of their observations.
DJI Mavic Pro review Although the main purpose of Mavic Pro – shot, this is a very dynamic drone. In sport mode, it is able to develop a speed of up to 65 km / h (no wind), to rise at a rate of 5 m / s and a decrease of 3 m / sec.
In addition to the remote drone can be controlled from your smartphone or tablet. Drone creates a secure Wi-Fi-network, which is connected to the mobile device. At the same time, all functions of quadrocopters, however, with natural constraints. He will not fly off at a distance greater than 80 meters and rises to a height of over 50 meters, and the maximum speed is reduced to 14 km / h.
Virtual, on-screen, “sticks” do not provide the same accuracy as the control hardware on the remote, but it’s not a problem because of the main application control mode smartphone – fast herself.
DJI Mavic Pro Drones DJI – an excellent choice for those who want to learn how to fly without buying process a dozen new vehicles instead of broken. For beginners there is an automatic take-off modes (quadrocopter rises to a height of 1.2 meters and freeze in anticipation of the pilot’s commands) and automatic landing (first drone will come down to a height of 50 cm, look, is there a place to land, and then sit down gently).
Circling the point of interest is possible in automatic mode, but in some subjects will be interesting intervention of the pilot, which is available adjustable height, radius and speed without crashing the overall trajectory.
ActiveTrack function provides automatic object tracking, implemented on the basis of image analysis, no bracelets-baits are required. To activate only need to select an object on the screen of your smartphone and send quadrocopters the reins. I tried this mode in simple terms – few moving foreign objects in the frame, a simple surface, a significant contrast between the background and object tracking. No comments – everything works as promised. In recognition of the image based two additional functions – shooting selfish and the inclusion of monitoring without the remote. Drone short distance recognizes the gestures and performs the appropriate action.
TapFly allows the pilot to set the direction of flight by touching the map on the screen of your smartphone. Quadrocopters go in that direction. This mode is useful if you need to fly is not at a right angle to the body, such as the trajectory requires certain skills.
Autonomy drone DJI Mavic Pro review system helps to avoid collisions with obstacles. Unfortunately, it is not omnipotent, since the camera only look forward and down. A dangerous situation can occur when flying in automatic mode, for example, circled points of interest, which is directed nose and main camera. Vigilance and skill increase has not been canceled, but the best guarantee for a restful sleep – buy an annual insurance, operating on the principle of motor hull insurance, the company’s own product QUADROCOPTER.ua. During familiarization with the drone I had a dangerous situation for automatic return to the point of take-off. The machine flew on a difficult path, and suddenly headed for the trees. Fortunately, he was within sight and I just took the management into their own hands – it is possible, in all automatic modes.
CAMERA
The camera in the DJI Mavic Pro review removable, but a good size for its smartphones. Its lens has a fixed aperture f / 2,2. Equivalent focal length of 35 mm camera – 28 mm, which makes the picture is not so distorted in Action cameras and retains a large sense of space in the frame.
Raw files from the camera, JPEG, and RAW can be downloaded for independent thorough review at this link .
Processed images are published in the gallery.
Learning test studio shots confirms the well-known truth: if you want to get the best results, shoot images in RAW.
The range of sensitivity 12 megapixel matrix – ISO 100-1600 (for video – up to 3200). At default settings built-handling system shows good results in terms of white balance and excessive passion for noise reduction, all over ISO 400 look too “plastic”. RAW in the form of the universal DNG-file contains a lot of useful information. At a minimum, the details. Even at ISO 1600 are present almost in full, and the noise only adds snapshot grain, and small and rather nice looking. Here are fragments of a still-life test at 100%. Left – the JPEG from the camera, the right – processed from RAW in Adobe Photoshop.
The RAW white balance does not play a role, but in the JPEG and shooting video is an important parameter. Automatic configuration gives good results, but for complex situations and effects, there are four presets and the ability to manually set the color temperature (in Kelvin) in the range of 2,000 to 10,000.
The shutter speed range – from 8 seconds to 1/8000, which is very important for the high-aperture lens.
He writes the video camera at a flow rate up to 60 Mbit / s. The choice of several options available – 24,25 and 30k 4k / s, Full HD 24, 25, 30, 48,50,60 and 96 to / from HD and at speeds up to 120 / s. There is a mode 2,7K – 2720h1530 pixels (24,25 and 30 f / s) suitable for Full HD editing with a decrease or framing. Unfortunately, RAW is not only the H.264 MPEG-4, however, the picture can be influenced within certain limits by asking sharpening mode (or rather, removing it at the same time getting rid of particular artefacts), and selecting one of the color reproduction options, among which there is an option to flatter curve D-Log (available on the website for free download LUT’y for proper conversion to sRGB images and REC709).

The first movie – from the camera, shot in 4K and preset D-Log, the second – its export from Adobe Premiere Pro version with cash LUT Mavic Pro D-Log to sRGB Enhanced.cube.
Two shooting modes: automatic and manual. With the first all is clear. Manual mode controls the exposure by two parameters – sensitivity and shutter speed, and the system tells you how accurately defined parameters. Relight application displays visually, there is an error indication in the third stage of EV. The absence of the usual shutter speed priority mode or the sensitivity is only quite strange, it is hoped that developers think about this question.
The camera is able to do a single frame, a series of three, five or seven shots, Exposure Bracketing (three or five exposures in increments of 2/3 EV), and, importantly, to conduct time-lapse recording (interval between images from two to 60 seconds, all nine values).
PERSONAL EXPERIENCE
Experience piloting quadrocopters I had (toy size of a matchbox does not count), but after a brief instruction and familiarity with documentation it was not that at all easy, but not nearly as scary (considering the price of the device and its potential danger to people on ground). The main advantage of the control system – the ability to keep the drone in a point in space, and DJI Mavic Pro review everything works fine. In confusion? Not a problem, let sticks and flying “will pause,” will be time to think and make the right decision.
Drones DJI – an excellent choice for those who want to learn how to fly without buying process a dozen new vehicles instead of broken.
Shooting camera quadrocopters is definitely different from the ground survey, in the first place – especially the position of the remote device, where there is a delay, and the effects of wind, and the characteristics of the drone. However, after some practice, manage to get to the desired point of shooting quickly and accurately enough, especially if you go in Tripod mode, the system allows you to move in space quadrocopter very slowly (3.6 km / h), software underestimating the sensitivity of the stick.
For video pilot skills are more important, because they allow you to get interesting spans due to the trajectory quadrocopters movement. However Automation Mavic Pro allows you to make high-quality video, even for beginners. Two modes – circled points of interest and follow the object is very useful for professionals.
Another detail – time. DJI Mavic Pro review is able to stay in the air for about 20 minutes (battery energy storage should be enough for a landing). During this time, you need to take off, find the point of shooting (and path for the video), do not forget to follow the safety (height, obstacles, battery power, and the distance from the take-off point), which is not used to, of course, difficult.
PROS: foldable design; almost pocket size; stylish design; long (especially by the standards of small models) the flight; excellent video transmission distance to the control; auto flight mode and shooting; high quality frames from the RAW after treatment
CONS: Because of the low mass flight stability is worse than that of large drones, which affects the quality of the video; JPEG-chamber process is too intense; in RAW significantly limit the dynamic range; Video can not withstand intense correction
CONS: Because of the low mass flight stability is worse than that of large drones, which affects the quality of the video; JPEG-chamber process is too intense; in RAW significantly limit the dynamic range; Video can not withstand intense correction
CONCLUSION
DJI Mavic Pro review – excellent, thanks to the compact size, the flight performance and ease of use, quadrocopter with excellent light. However, if the quality of photos and videos is paramount for you to look at the model of the Phantom line. At a comparable cost, they give a better picture, although at a disadvantage in the dimensions
