DJI Mavic Air Review – A rookies perspective

Introduction

I’d been thinking about buying a drone for a long time. On a recent holiday in Thailand, as I was bouncing around on a quad-bike trying to film the rest of the family, I knew drone footage would look an order of magnitude better. A couple of the guys in the office wax lyrical about theirs so I thought it was about time I took the plunge. This rookie was about to get his first aircraft.

For once, I kept my sensible head on and decided against buying the most expensive model by default – but which one? All that I was sure of was that it had to record 4K footage. The guys in the office had nothing but praise for DJI drones so choosing the brand was straightforward, the Spark ruled itself out by not recording in 4K, and then DJI announced the Mavic Air.

With its SmartCapture, FlightAutonomy 2.0 and Advanced Pilot Assistance Systems to help me take great footage from the off and preventing crashes – I was sold. To maximize my flight time, I ordered the Mavic Air Fly More Combo at $ 999, the two extra batteries alone justify the difference in cost, while also coming with an accessories case, extra spare propellers and a charging hub allowing me to charge all batteries at once.

Un-boxing, Design & Build

I’ve unboxed many consumer electronic items, but given my unfamiliarity with the drone genre, I was unprepared for the plethora of ‘stuff,’ many items unrecognizable to this rookie, that came in the box. And having no frame of reference on how big the Mavic Air was it took me a few minutes to even find that!

When folded, I could just about cover the Mavic Air with my iPhone 8 Plus, it’s that small. I’m no expert, but for this rookie, it seems to strike just the right balance between size and weight while being functional enough to be more than a toy, but not too big to be unwieldy. So far so good.

Like the best Transformer robot, you prepare the drone for flight by folding out the four propellor arms, starting with the rears which first fold down and then up and out, with the fronts merely pivoting outwards towards you. It felt a little odd at the start, but now I’m used to it. Pop off the camera/gimbal protector, and you’re good to go.

At this point, you’ll notice how well designed and built the Mavic Air is. There is elegant robustness about it that is reinforced when you’re unfolding the propellor arms with nothing squeaking, and everything is tight and well engineered. The camera system is nestled within the body affording it protection from knocks and maybe even crashes.

The battery is held firmly in place by two sturdy spring-loaded locking sliders which will resolutely ensure the battery stays put in flight. While on the subject of the battery, to remove the battery in the Mavic Air you have to unfold all the props.

I’m less of a fan when it comes to the included remote though. The remote is exceptionally portable and pulls the same Transformers trick, folding out its antenna, grips for holding your mobile which also exposes the joysticks to screw in. While it’s built to the same standard as the Mavic Air itself, the mechanism for ‘gripping’ my mobile is slightly flawed.

The larger your phone, the more trouble you may have. I have an iPhone 8 Plus, and it’s fiddly trying to insert the phone into the lightning connector (USB-C & MicroUSB connectors are provided) and the grips only just about take it after having to remove my thin case. During use, the phone starts to slip out of the grips and when you push it back in you end up pressing the power button and turning the phone off. I’ve even thought of procuring a cheaper/smaller phone to use specifically with the Mavic Air.

Flying

Eager to get into the air, I plugged everything in to charge, usefully DJI has battery indicators on the batteries themselves and the remote. Just pressing a button gives you a visual display comprising of up to four bright dots to indicate battery charge. Very much akin to Apple’s laptops from a few years back.

It’s also possible to fly the drone just from your smartphone which is great if you want to take some quick footage. In this configuration, the range is limited as it’s effectively using Wi-FI to 80m distance and 50m in height. That figure when using the controller increase to a maximum of 4km dependent on country.

All juiced and ready to fly I headed out and found a suitable spot for my first flight. I must confess at this juncture to being extremely nervous – the last time I flew a remote anything it was a remote controlled helicopter that I crashed almost immediately which then subsequently went on to empty my wallet in repair costs, fingers well and truly burnt.

To avoid random power-ups & downs, you press the power button once and then a second time on both the remote and the aircraft to confirm.

  • Mavic Air powered up – check
  • Remote on – check
  • The phone just about held by remote – check
  • DJI Go app is running on iPhone – check

I discovered two ways to get the aircraft into the air – the old school way is to pull the two joysticks down and together to start the propeller motors. Once started, push the left stick forward which controls your altitude, and up she goes.

The second way and far more next-gen is to press the Takeoff button in the DJI app, slide the takeoff slider to confirm, and the Mavic Air takes off, goes to an altitude of 1.2 meters and hovers in place – no crashing, no drama.

It’s the same to land, you can adopt the old school way or select one of two buttons from the DJI app. One being land now right where you are, while the other will use GPS to return and land to its takeoff point. The latter option is also available as a physical button on the remote – useful for when your phone slips out of the grips!

So my first flight consisted of a straight up and down – not precisely in the same league as SpaceX, but its a start and it was enough to get rid of my nerves. Don’t forget I’m a rookie and I’ve never been up close with one of these aircraft and already I was impressed, time to look at what this could do in more detail.

If you simply wanted to fly the Mavic Air you can use the remote sans phone, but you remove access to any of the enhanced flight, video recording and photography capabilities accessible via the DJI Go app.

Like my wife, the Mavic Air has eyes in the back of its head. Actually, it has two facing down with an additional two facing forwards – whose purpose in life is to provide collision avoidance capabilities. Its sides are sensor-less though so you have to be careful with those sideways movements. With clearly defined objects this function works as advertised by either flying around the object or ceasing forward movement and proceeding to hover in place. I didn’t test with tree’s that had lost their foliage as I didn’t want to push my luck – I wasn’t 100% certain the sensors would make out their individual branches – may be a test for another day.

When fully charged – I was getting approximately 20 minutes of flying time from each battery. The Battery Charging Hub charges up to four batteries in sequence according to their power levels, from high to low. Each battery took circa 50 minutes to charge.

Having spent time learning how to maneuver it was time to explore its QuickShots smarts. Everything the Mavic Air see’s you see via your phone screen. Selecting QuickShots gives you access to the following Rocket, Dronie, Circle, Helix, Asteroid, and Boomerang modes, with the latter two being new to the Mavic Air.

Simply select your mode, choose your target and go. The Mavic Air does the rest creating amazingly professional shots following its predefined flight path per the style you’ve selected.

ActiveTrack follows up to 16 subjects, you can select precision tracking, or you can broaden the target area. During regular walking or running the Mavic Air locked onto me and performed as expected. Of course, you can lose it if you do a quick 180 and run under it – but hey, this thing isn’t Skynet thank god. I’m not 100% certain how successful it would be following us on quad-bikes in the jungles of Thailand, but we’ll find out at some point in the future.

While not a priority for me, the Mavic Air can be controlled by gestures via SmartCapture to take the ultimate selfies.

So yes, I did crash it. Attempting an indoor hover, with no GPS, in a bright white environment, the inevitable happened. Wall meet aircraft, aircraft meet wall. The only damage, however, was to one propeller tip. It’s quick and easy it to remove and replace a propeller. Ensure the replacement prop has the same markings as the one your replacing, and it’s as easy as popping the old one off and replacing with a new one. No tools and you’re soon flight capable again – phew!

Video Quality

Of course, fun aside, the primary raison d’être for my investment was for aerial filming and photography, so how did it perform in that regard?

For comparison, I was joined by the other guys and their drones giving us the holy trinity of the DJI Spark, Mavic Air, and Mavic Pro. Time for some pixel peeping.

All the footage that we captured, from all three drones, used the default settings with NO profiles applied. At some point in the future, I’ll invest more time in delving into the image settings to find the perfect configuration.

When comparing the highest possible resolution and bit-rate captured the Spark is the softest due to having a maximum resolution of 1080p as opposed to the 4K of the Air and Pro. The Mavic Pro looked to be slightly sharper, while the Mavic Air has a more vibrant and warmer image

Next, we sped up the captured footage that we shot with all drones flying the same path. This helped us compare stability from their gimbals. Given the conditions, they’re all pretty damn stable, but a slight advantage has to go to the Pro.

The Mavic Air has a wide range of video recording options when it comes to resolution and FPS

When comparing the 4K and 2.7K at 30 fps footage it will come as no surprise that the 4K provides the sharpest picture. But, it’s negligible when compared to the upscaled 2.7K footage, so if you want to save some space on your memory card I have no problem recommending this mode.

The 2.7K footage at 60 fps started to lose some of the fine detail, especially in our shots that included foliage.

Finishing off with the 1080p at 120 fps, you lose too much detail, and it lacks the sharpness of the other resolutions, and noise reduction is being applied with artifacts being introduced. Of course, the main reason to use this mode is for the 120fps to allow slow-motion footage.

Don’t forget what I said earlier – all our comparisons used the drones default settings with no profiles applied. I do not doubt that given time I’ll be able to find a better combination of parameters for different conditions.

Don’t forget to check out the YouTube video at the top of this page to see further examples of the Mavic Air video quality.

Photo Quality

The Mavic Air allows you to shoot in RAW which was one of the criticisms that I’d heard about the Spark, with the stills from the Mavic Air generally being very good. The camera is pretty decent in the Mavic Air, it falls short of some of the top flagship smartphones in some regards, but this is mainly if you’re pixel peeping. Of course, its shots are also helped by its perfect gimbal stabilizer. While good in normal conditions, for low light you’d better look elsewhere, with small sensors you should really try to keep the ISO as low as possible.

Not necessarily a fair comparison but we also shot our color chart in the lab to use as a comparison.

HDR Stills

When shooting in HDR from the Mavic Air, you do see in the image highs and lows, BUT it does introduce ghosting on moving object such as people, which is hard to avoid. We found we got better results by taking the shots from the Air and performing the processing on a computer.

Panoramic’s

Being honest, the panoramic shots where a bit of a disappointment when they were stitched together by the Mavic Air. Certainly, in our tests, it just wasn’t that smart when aligning the individual frames. In the Sphere 360 Pano, there was a lot of examples where buildings were misaligned. This was less obvious in the other panoramic modes, but they suffered from ghosting when moving objects were in the frames, such as cars.

Again, the panoramic shots stitched together on a computer in a desktop app were an order of magnitude better. So unless you’re desperate to send a panoramic shot while in the field, we’d recommend stitching them together outside of the aircraft on a computer

One additional point to note is that Panoramic and shooting in RAW are incompatible – confusing as you don’t get any warning and it goes through the motions and captures the separate images but doesn’t stitch them onboard.

Verdict

Coming from a rookies perspective I love the Mavic Air. For me, given the price, it is the perfect drone.

It’s compact and light enough when folded to take most places, with its massive array of shooting modes you can quickly and easily make great shots and footage. And the quality of that captured footage is more than good enough for what I need.

Downsides? Just a few.

I understand the compromises in making a remote that has to fit many phone types but, for me, it was the one major annoyance in the overall package.

When it comes to still photography, we got better results by post-processing on a computer.

Having to unfold the arms to change the battery still irritates, especially as you can’t charge the battery while it’s in the drone

Those are small niggles though in an otherwise excellent package, and if you’re currently looking to buy your first drone, and want 4K footage, I highly recommend the DJI Mavic Air.
