Pros: Stability and "intelligence" of flying
Cons: Non-raw video stream
Opinion: This review refers to the Pro model: when the relevant card is published, I will transfer the text there. RnrnAll PhiTom series Dji quadricons are excellent flight devices. Stable, smart, well conceived and made. To have a model that can provide photo performance not lower than the minimum quality requirements, we had to wait for 4 Pro (followed by 4 Advanced). All the others, before, left to desire in this regard. The reason is simple: the 4 Pro mounts an inch sensor, far larger than the predecessor of two thirds of an inch. The latter I had seen on the Sony Action Room: it excels in its subdivision, even considering the 100 mbs bit rate (high resolution), high in this category, and beneficial for the video stream. But to make quality photos wanted something more. That something came with the 4 Pro, exactly. If with the Phantom 3 and 4 Pro Pro sensor were not visible on the artifacts screen, even in the sensesMinimum, with 4 Pro this disadvantage is less obviously perceptible. Also, the goal. The focal length changes from an equivalent to 20 mm in the Leica format to an equivalent of 24 mm. Which brings in the important novelty of the mechanical shutter. Thus, the annoying rolling shutter phenomenon is overwhelming. It is active up to 1/2000 shorter time, while the electronic shutter can go to 1/8000. And for the first time, the diaphragm can be manually adjusted to f11, while previously it was fixed at maximum aperture. I would be occupying too much space here if I were to dwell on video features, but one feature here is to mention it: the automatic obstacle avoidance device. Here, there are 12 sensors, including visual, ultrasonic and infrared. The 4 Pro was the first Phantom to mount them. First, the access threshold for this device was Mavic, but it still mounts a two-thirds dInch (and now some avoidance sensors are also on the Spark economy, but always with the smaller sensor). Because this aid is active, in addition to an ambient brightness level of not less than 10 lux and not more than 300, the switch on the controller is set to P, but do not worry if you notice it has inadvertently shifted: Mode P you need to access a remote configuration of the flight software to match. Which is called Dji Go 4, and gives you the ability to consider smartphones and tablets manufacturers in Android environment that do not allow for OS updates: if your device is earlier than version 4.4 and you do not want to change model, you will have to resign Buy a Phantom 3 and match it to the Dj Go not 4. In the Apple family, however, you can pair it with a less recent model as long as it can be upgraded to IOS 9. Fixed the connection problem - but be careful: an updated operating system model But little "powerful" does notIt will feel a real-time streaming video refresh - but be careful: personally I did not dare to throw the quadricopter against the thinner cables of the service cables, for their little section being unrecognizable. Water should also be recognized as an obstacle, albeit with the word just mentioned. Another safety factor is the possibility of opting for two frequencies: not only 2.4 gH, but also the least "crowded" 5.8. In addition, this high-end Phantom model allows dialogue with Russian and American satellites. It therefore points to a concept of redundancy, as in the case of sensors, to enhance flight safety. About which I recommend to read carefully the Enac legislation, updated to the amendment of December 22, 2016. It - for drones total weight less than two kilograms and P4 stops at 1388 grams - exempts from obtaining a license on condition That the following requirements apply: do not exceed 200 meters longitudinally and 70 metersin height; Use the drone for recreational or recreational use, non-profit; Do not overtake populated areas (moreover, even those who obtain the license can not do so, unless they have free passers-by). Narrow penalty for non-patented users should be inhibited by the use of the viewer, as the condition that does not allow the classification of the drone as a simple aircraft model rather than an aircraft (the original intonation of sewn rule on the aviosurpose helicopters is perceived here, No video camera), it is precisely the absence of visual aids for driving, but actually the ability to use a tablet for vision is a safety factor. In any case, be aware that the controller allows full control over autonomy, even if it finds the heavy limit to be limited to the area within which the drone can be seen with a naked eye: very limited in height, indeed. Controller whose tab bracket accommodatesModels up to 8 inches (while Phantom 3 standard and Mavic stop at 5.5 inches). The two joysticks are adjustable in height and have a reactivity that varies according to the installed guide program. A very important function (the command of which is present as others on both the controller and the external software) is RTH (Return To Home): pressing a button or taping the tablet drone will return to the base using the memory Of the route already performed (it is advisable to preset an appropriate return height in the software before using the function). There are also many other "intelligent" driving features, but they would have many pages in addition to this review if you treat them. The fact that photographic quality - shots are also available in DNG raw "universal" format, while obviously if you shoot photos during a movie, they will be taken from the compressed stream of the video (you will get up to 8.8 MP if you are shooting in4K), with a much smaller yield (however, it is possible, after cessation of the movie, to fly in flight to the photographic mode) - is now acceptable from a photographic point of view, you can complain that the video can not be even ' It worked in raw, which is possible on the top model Dji Inspire (this is useful not only for the more workability of the raw format, but also for the cleansing of the signal that such a format entails). The Adobe ACR module does not yet have a lens correction profile mounted on this model (it stops at the non-Pro version, which is unusable because of different focal points). Continuing with the post-production process, I note that in situations where a flat profile is needed, there is a possibility to count on a Dlog in the machine, but this is most useful for the video segment, which can not be recorded uncompressed. Also with regard to the video stream, let me know that ecCunning program Da Vinci Resolve makes available some dedicated LUTs. That said, by the way, I have highlighted one of the most important advantages of the 4 Pro: the maximum expression of the Phantom series with regard to image quality, also represents the upper limit of normal portability: there are dedicated backpacks that allow you to carry your shoulders very easily 4P and All its accessories, while Inspire has significantly larger footprints. Better still be flying your professional reflex, but I will not mention you costs and complications, so you will not impress ... |
