Final yr, DJI confirmed what was doable in a small drone with the Mini 3 Professional by becoming tons of know-how and a high-quality digital camera right into a sub-250 gram drone. Following that up was by no means going to be simple, however now (after quite a few leaks) it’s unveiled the Mini 4 Professional with an extended record of recent options.

Apart from one enchancment, the digital camera is basically the identical. Nonetheless, it has new omnidirectional impediment sensors that get rid of the blind spots on the Mini 3 Professional. It additionally comes with a brand new characteristic known as ActiveTrack 360 that permits you to program digital camera strikes when monitoring a topic.


  • Maneuverable
  • Improved impediment avoidance
  • New ActiveTrack 360 characteristic is nice
  • Stable picture high quality


  • Nonetheless removed from crashproof
  • A bit costly
  • Not the perfect for night time scenes

Small drones are one of the simplest ways to trace fast-paced motion, as they’re maneuverable and fewer inclined to break when crashing. With all of the enhancements, the Mini 4 Professional is healthier and safer at that than its predecessor — a minimum of on paper. Now, let’s discover out if it lives as much as that in the actual world.


The Mini 4 Professional continues to be beneath 250 grams so it may be flown and not using a license or registration in lots of areas, but it surely has delicate design adjustments throughout. The 4 forward- and rear-facing sensors are actually positioned in order that they will see to the edges as effectively, and the physique is a little more streamlined. It has bigger cooling vents, barely smaller rear arms and new touchdown toes on the entrance. The digital camera/gimbal protect is smaller and simpler to placed on, and it has a brand new guard that protects the propellers when it’s saved.

As earlier than, the gimbal tilts up 60 levels and down 90, and the digital camera flips 90 levels to provide you full vertical decision for social media. On the rear is a microSD port, and the Mini 4 Professional has 2GB of inside storage for emergencies.

The Mini 4 Professional comes with one in every of two controllers, the essential RC-N2 that requires a smartphone, and the RC2 with a built-in display. Because it makes use of DJI’s new Ocusync 4 transmission, first launched with the Air 3, it solely works with the brand new controllers and never the older fashions — for now, anyway.

You should buy it with a $55 ND filter set for sunny days, which I’d suggest in case you can afford it. DJI additionally affords a wide-angle 18mm equal lens attachment ($40), but it surely has vital barrel distortion and might trigger focus points.

The drone additionally helps DJI’s Lightcut, an enhancing app that permits you to generate fast movies for social media. As DJI says, it permits “one faucet era of fascinating movies by merging ActiveTrack, MasterShots, and QuickShots footage,” whereas automating sound results and extra. It additionally works wirelessly, so there’s no must obtain footage to your smartphone.


Given its small dimension and maneuverability (and the identical sensor as DJI’s Motion 4), you’ll be able to consider the Mini 4 Professional as a flying motion digital camera. The sunshine weight (and low value in comparison with, say, a Mavic 3 Professional) additionally makes crashes much less consequential.

Most pace is a decently quick 35 MPH in sport mode, or 26 MPH in common operation. It may possibly deal with winds as much as 24 MPH, a powerful determine for a sub 250 gram drone. In operation, it might probably appear to be it’s being buffeted pretty laborious by the wind, however you wouldn’t understand it from the footage due to DJI’s gimbal and stabilization know-how.

The Mini 3 Professional was successfully blind on the edges, however the Mini 4 Professional affords safety throughout just like the Mavic 3 Professional and Air 3 — due to 4 new omnidirectional sensors on high and two on backside (together with a time-of-flight sensor). It additionally makes use of DJI’s APAS, which affords computerized braking and impediment bypass for additional safety.

In case you’re spending $760+ on a drone, you could not wish to check the impediment detection limits. That is my job, so I had it comply with me whereas I walked and biked amongst timber and different potential snags. I did have a couple of crashes, however right here’s what I discovered on easy methods to keep away from them.

The sensors are visible, in order that they don’t work in dim mild. And dense forest with effective branches is a no go — the omni sensors can miss these, however the propellers gained’t. Lastly, the Mini 4 Professional detects obstacles finest when touring ahead, much less so when going sideways, and worst of all when flying backwards.

It did work round well-spaced timber with thick branches and loads of leaves, close to buildings and customarily round well-defined obstacles. It was in a position to maneuver round these, select first rate routes and reacquire topics in the event that they disappeared. That helped me seize some good motion footage, although one ought to all the time stay cautious of accidents.

ActiveTrack 360 provides digital camera strikes to the same old topic monitoring to create dramatic photographs. It seems complicated at first, however the thought is fairly easy. You utilize the so-called steering wheel to “draw” a route on concentric circles, and the drone will comply with it, ducking any obstacles it encounters.

You possibly can change parameters together with the interior and outer radius, interior and outer top, digital camera pace and floor proximity. That makes it doable to get all kinds of photographs. The difficult half was determining which facet the drone thought-about to be ahead and backward — DJI ought to work on this to make issues clearer.

In case you plan rigorously you may get some beautiful, swooping ActiveTrack photographs. The same old impediment caveats apply, although, and it additionally provides complexity — as a result of you need to determine the place the drone goes to be while you arrive at your finish level. With all that, it’s finest to apply in an open space earlier than making an attempt it in a posh setting.

In fact, the Mini 4 Professional nonetheless has DJI’s computerized modes geared toward social media customers, like MasterShots, QuickShots and Panorama together with Hyperlapse. It even contains the Waypoint characteristic from the Mavic 3 Professional, which helps you to pre-program complicated drone strikes and repeat them — a classy characteristic for a small drone.

For the latter characteristic, you launch the drone and choose the Waypoint operate, fly to a spot of curiosity and set the right digital camera angle. As soon as there, you faucet “+” on the display (or hit the C1 button the RC2 distant) to program a waypoint. Repeat that course of by all of your factors of curiosity, and when you’re completed, you’ll be able to play again the sequence. The drone will easily fly to every level the identical approach every time, so you utilize it to indicate a scene throughout the day after which later at night time, as an example.

The Mini 4 Professional makes use of Ocusync 4 transmission first seen on the Air 3 that sends 1080/60p video as much as 20 km, in comparison with 1080/30p over 12 km with Ocusync 3. These distances are decrease right here in Europe due to transmitter energy guidelines.

In use, it gives a noticeable enchancment in connectivity, with fewer dropouts and far better vary — even when the drone goes behind obstacles. The change may be very noticeable right here in Europe with smoother video and dropouts now very uncommon. It must be even higher within the US, the place you might ship the Mini 4 Professional on a fairly lengthy journey.

The usual 2,590 mAh Clever Flight Battery has a bit extra capability than the Mini 3 Professional’s 2,453 mAh cell, however vary stays the identical at 34 minutes. In real-world flying, we noticed about 25 minutes earlier than listening to the return-to-home warning, so plan accordingly.

You probably have a Mini 3 Professional, its cells seem like suitable with the brand new drone, in order that’s factor in case you already personal that mannequin. Within the US, you may get the Plus batteries that present as much as 45 minutes of vary, however native guidelines block their use in Europe.

The RC-2 first seen on the Air 3 is DJI’s third display controller after the RC and the RC Professional. It’s considerably higher than the RC, with a brighter display, higher really feel and extra exact controls. The opposite possibility is the non-screen RC-N2 (requiring a smartphone), which has similarities to the RC-N1 mannequin however with O4 compatibility.

The Mini 4 Professional’s digital camera has the identical 1/1.3 twin ISO sensor as its predecessor, utilizing an equivalent 24mm equal lens with a set f/1.7 aperture. That’s a fairly sizable sensor for such a small drone, only a bit smaller than the 1-inch sensor on the Mavic Air 2S.

The distinction is that it now helps 4K slow-mo at as much as 100 fps, or 1080p at 200 fps. The movement is embeded 30fps, but it surely’s nonetheless a pleasant characteristic for wildlife, crashing waves and extra. That’s on high of 4K at as much as 60fps and 1080p at 120fps. It has a two occasions digital zoom for 4K and 4 occasions at 1080p, with a slight loss in sharpness.

There’s additionally help for DJI’s D-LogM, which boosts dynamic vary and provides you extra flexibility in publish. DJI has a LUT that makes it simple to transform it to common video — however some enhancing is required for finest outcomes. It’s also possible to shoot in DJI’s HLG mode, which once more boosts dynamic vary. You possibly can see the outcomes instantly on an HDR TV, however you’ll must do an HLG to REC.709 color-space remodel to make use of it with common video. Each help 10-bit 4:2:0 seize for improved constancy and lowered banding.
