Review: DJI’s FPV drone combines DJI features with the fun of a racing drone

DJI has officially entered the FPV (first-person-view) drone market. Typically, remote pilots interested in the type of immersive flight experience FPV drones provide, including the ability to maneuver through tight spaces and in close proximity to objects, all while performing aerobatics such as flips and rolls, had to also master an entirely different set of skills.

Soldering, understanding how to configure an RC controller specifically for a drone, learning how frequencies work, and installing the right motors are just a few disciplines a would-be FPV pilot must undertake to create a safe and effective FPV flight system.

Some people who delight in these challenges will always enjoy the process of building, but DJI is betting many more people will want to cross over to FPV with an intuitive solution, and its FPV drone is ready to fly right out of the box for $1299. As an added bonus, the system is equipped with GPS, obstacle avoidance sensors, and a Return To Home feature – ensuring that beginners will be less likely to crash or lose their drone.

DJI tells us it set out to create a cinematic FPV drone and combined elements of its Mavic series with the features and functionalities of traditional FPV drones. Is this a product that will appeal to a broader audience, especially beginners? Or, are there downsides that would make some users look at more traditional drone models?

We had the opportunity to test DJI’s new FPV drone, so read on to discover if this is your ideal introduction to the world of FPV.

  • 795g (1.75 lbs.) total weight
  • 255×312×127mm (with propellers)
  • 1/ 2.3” 12MP CMOS image sensor
  • 35mm equivalent lens (150º FOV)
  • Ability to capture photo and video on the same flight
  • 4k/60p and 1080/240p video at 120Mbps
  • H.264 and H.265 codecs
  • Emergency brake and hover
  • Obstacle avoidance sensors on front and bottom of aircraft
  • OcuSync 3.0 (O3) transmission system for 10km range, dual frequencies, 50 Mbps bitrate
  • 20-minute max flight time
  • 140 kph (87 mph) max speed
  • Memory card holder in goggles in case drone is lost

Here is a basic comparison chart to get an idea of the difference between a traditional FPV drone and what DJI offers.

The hardware

I tested the DJI Standard FPV Combo ($1,299), which includes the drone, FPV Goggles V2, and the remote controller 2. As usual, DJI offers an additional ‘Fly More’ combo that includes two extra batteries and a 3-battery charging hub for $299.

The goggles, which are 202x126x110mm with all four antennas attached, activate with the help of an 1800 mAh 9V battery that’s connected by a USB-C power cable. Lasting an estimated 110 minutes between charges, it’s light enough that it can hang down by your side while in operation. Still, I typically put the battery in the pocket of a coat I was wearing as an extra measure to ensure the battery didn’t get disconnected.

DJI’s FPV drone features a new OcuSync 3.0 transmission system. It boasts a 10 km (6.2 mile) range, dual-frequencies, a 50 Mbps bitrate, and three options for first-person-viewing – a Low-latency HD mode for near-real-time feed and clear image, Smooth mode for higher frame rates and decreased latency, and Audience mode. The latter option allows others wearing V2 goggles to join in and view your real-time feed.

The FPV drone will also operate on DJI’s Fly app, introduced in 2019 for the Mavic Mini. It’s cleaner and more pared down for a superior user experience. The app is still in beta and wasn’t available for testing with the FPV drone. Nevertheless, I activated all of the drone’s features through drop-down menu items in the goggles.

The joystick-type button on the top lower-right-hand corner will guide the pilot through numerous settings and features for both the remote and camera. The goggles receive up to 810/60p video transmission in high-quality mode and less than 28 milliseconds of latency, or 120 fps in low-latency mode.

V2 of DJI’s remote controller is ergonomically friendly and gives you immediate access to features you’ll need including Return to Home, a gimbal wheel that can pitch the camera upwards and downwards at 90-degree angles, the ability to switch back and forth between flight modes, plus a button to stop the drone and put it in a stable hover if control of the drone is suddenly lost. You can also lock the gimbal at an upward or downward angle.

One note: I did not receive the hand motion controller due to shipping delays. This review will be updated once I’ve tested it out.


Photos and Video

The camera uses a 12MP, 1/2.3” sensor, providing a 150º FOV, and is mounted on a 1-axis gimbal. Capable of capturing stills and video up to either 4K/60p, or 1080p/120p for 4X slow motion, at 120 Mbps, the camera uses an electronic roll axis and RockSteady image stabilization. While it provides smoother imagery than most FPV drones, it’s not comparable to the 3-axis mechanical image stabilization offered up in DJI’s other series of photography drones, including the Mavic.

DJI’s FPV drone takes decent photos at times. If you’re serious about aerial photography, though, the Mavic 2 Pro is a better investment.

Remote pilots can capture .JPG and images or .MP4 and .MOV clips all in the same flight. It’s easy to toggle back and forth between these modes. While the photos I captured are decent enough, there were times when the drone was tilted, resulting in photos with crooked horizons. Also, photo resolution is limited to 3840×2160, the same as 4K video. Anyone serious about drone photography will probably want to look at a more-photo-centric model; the FPV drone is fun to fly but is not a replacement for traditional photography drones.

There’s a fair amount of fisheye distortion from the FPV drone’s wide lens, though a distortion correction function in the camera menu can be applied.

I typically enjoy recording aerial videos with the gimbal tilted down. With the wide FOV on the FPV drone, it is likely parts of the propellers will become visible. I also noticed some fisheye effect in some of my clips. To prevent this, you can either tilt the gimbal up as the aircraft moves forward or adjust settings through the goggles. To do this, access Advanced Camera Settings in the Camera menu and select Distortion Correction.


In-flight

Obstacle avoidance and flight modes

There are four obstacle avoidance sensors on the FPV drone – two in the front of the aircraft and two on the bottom with an auxiliary light that helps with precision movement in low-light environments. Obstacle avoidance sensors only work when the drone is flown in ‘N’ or Normal mode. This mode is suitable for beginners and highly recommended for those flying an FPV drone for the first time.

An auxiliary light helps with precision in low-light conditions.

You’ll also be limited to flying to 50 km/h (31 mph) in normal mode. The drone is stabilized the entire time and will slow down if it approaches a forward or downward-facing obstacle. ‘S’ or sport mode disables obstacle avoidance sensors and ups the excitement factor. The drone can travel up to 97 km/h (60 mph) and can perform pitches and rolls at limited angles, all while maintaining altitude and stabilization for the entire flight.

In normal mode, you can’t fly quite as aggressively, but obstacle avoidance sensors are active. This is a good setting for first-time FPV fliers.

‘M’ or manual mode is reserved for the experts. One may believe, at first, that manual mode can be triggered through the remote with the press of a button. It’s a bit more complicated. Operating a drone in Acro mode is challenging, to say the least. While flipping and rolling a drone looks fun, in reality, it’s easy to get disoriented. DJI anticipated the potential hazard of a first-time user accidentally activating manual mode from the remote controller.

You can crank the speed up to 97 km/h (60 mph) in Sport mode, though that still falls short of the 140 km/hr (87 mph) you can achieve in Manual mode.

As a result, users can only activate manual mode with a series of steps from the menu options through the goggles. Add in the fact that you can fly up to 140 km/hr (87 mph) in this mode, and it’s easy enough to lose control, even when Emergency Brake and Hover can still be activated.

DJI’s Virtual Flight app simulator was created so pilots could practice FPV maneuvers without a crash risk. Nevertheless, without a lot of flight experience, an accident is still a strong possibility. Practicing in an open space such as a field or park cannot be recommended enough.

Odds and Ends

Looking at DJI’s FPV drone, the battery is noticeably massive in scale and helps balance out the aircraft. At 2000 mAh, DJI’s Intelligent Flight batteries offer up to 20 minutes of flight time – a huge improvement over typical FPV drones. As a bonus, they’re not the typical LiPos that can catch fire if overcharged or not stored properly.

DJI’s Intelligent Flight batteries offer up to 20 minutes of flight time – a huge improvement over typical FPV drones.

A flap under the camera houses ports for a MicroSD card and USB cable should you want to make updates to your drone through your computer. There is also a MicroSD slot located on the goggles. If you lose your FPV drone, you’ll still retain a memory card. This is an incredible new feature for those concerned about losing their imagery in the event of an accident. I hope DJI implements this concept in some way on future models.

What’s it like to fly?

In both ‘N’ and ‘S’ modes, DJI’s FPV drone is a great deal of fun to fly. It’s also an incredibly reassuring experience. Besides the Return to Home button, there is a bright white ‘H’ that pops up in the goggle’s viewfinder. It marks where you are relative to your launch point at all times. The system is also equipped with ADS-B technology. During a recent flight, I was immediately notified when a helicopter was nearby and was given ample time to adjust my flight path and altitude.

One downside is that even though this FPV drone is relatively compact, it is quite noisy. It emits a high-pitched squeal that can be heard from several hundred feet away. Flying discreetly is out of the question. During one of my first flights, my daughter joked if it was the drone or ‘the ice fishers on the frozen lake screaming.’ DJI has worked tirelessly on improving ESCs and designing more aerodynamic propellers. Curiously, these updates weren’t applied to the FPV drone.


Conclusion

Anyone hesitating to enter into the world of FPV because they didn’t have the time or patience to learn about all the factors that go into building a capable system will naturally want to try out DJI’s latest release. As mentioned at the beginning of this review, it’s an out-of-the-box product that can be activated almost immediately. When you add in fail-safe features, including GPS, Return to Home, Emergency Brake and Hover, it makes it that much more enticing to dive in.

That being said, there are a few concerns that come to mind. Traditional FPV drones are known for being resilient. Lightweight and constructed out of flexible materials made of carbon fiber, for example, they can crash into objects and require a motor replacement or a bit of soldering. DJI’s FPV drone consists of a tough plastic shell that will break with a high enough impact.

DJI’s ‘Fly More’ combo for the FPV drone includes two extra batteries and a 3-battery charging hub for $299.

The ability to truly freestyle, fly close to objects, and through narrow spaces is part of what makes FPV flight exhilarating. If you feel like you’re going to significantly damage your drone and ship it off for repair every time it collides with an object, the true joy of flying FPV will be stifled to a degree.

I had the unfortunate experience of crashing my DJI FPV loaner in manual mode, and it needed to be sent back to DJI for repairs. Even if I possessed the skills required to build and repair FPV units, it wouldn’t have been possible for me to do it myself. People who like to customize their builds and tinker likely won’t want to be at the mercy of one manufacturer when it comes to repairs or parts replacement.

Another issue that will bug some purists is the inability to replace or use more than the camera built into DJI’s FPV drone. It isn’t designed to carry an additional payload. Pilots won’t be able to attach a GoPro or OSMO Action camera, for example. The lack of flexibility in the camera is limiting and will be a turn-off for some FPV filmmakers.

I had the unfortunate experience of crashing my DJI FPV loaner in manual mode and it needed to be sent back to DJI for repairs.

Geofencing is another longstanding feature of DJI’s that rubs some people the wrong way. While all pilots need to be safe and compliant, some have switched to other drone brands to avoid and restrictions it brings up altogether. Even if you remain low to the ground, the drone will not take off if the airspace is considered restricted.

What will appeal to almost anyone is the long-range flight this drone offers. FPV is traditionally associated with close range and choppy analog feeds. If you stray too far from your home base, you run the risk of losing connection completely – which is a potential hazard. With DJI’s FPV drone, you can fly much longer distances so long as you remain within visual line of sight.

DJI’s FPV drone is certainly going to appeal to those who want to get into this style of flying. Purists who’ve already built advanced FPV drones that are resilient and carry their preferred camera will likely pass on this one. My main concern is that most remote pilots new to FPV won’t truly be prepared to operate in manual mode. While flips and rolls look exciting, it takes a lot of practice and perseverance to get the right feel for it. DJI Care Refresh is available in any event.

What we like

  • GPS, Emergency Brake feature, Return to Home, Hover
  • OcuSync 3.0 for clear transmission and long-range
  • 4K/60p video
  • Modes to suit beginner and advanced pilots
  • Activates and is ready to fly right out of the box

What we don’t

  • Lack of ability to switch out cameras
  • Extremely loud
  • Will likely need to be sent to DJI for repair if crashed

Pentax K-1 and K-1 II firmware updates include astrophotography features (depending on where you live)


When you use DPReview links to buy products, the site may earn a commission.

Yesterday, Ricoh quietly released firmware 2.50 for its Pentax K-1 and K-1 II DSLRs. However, the features you can expect to gain from this update may depend on your geography.

Ricoh’s English-language firmware pages for the K-1 and K-1 II state that firmware 2.50 delivers “Improved stability for general performance.”

However, astute Pentax users noted that Ricoh’s Japanese-language firmware pages (translation) indicate that the update also includes a limited feature called “Astronomical Photo Assist,” a collection of three new features designed for astrophotography: Star AF, remote control focus fine adjustment, and astronomical image processing.

Star AF is intended to automate focusing on stars when using autofocus lenses. Rather than manually focusing on a bright star and changing your composition, it promises to let you compose your shot and let the camera focus.

Remote control fine adjustment allows users to adjust focus without touching the lens and requires Pentax’s optional O-RC1 remote. Astronomical image processing will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

Astronomical image processing on the K-1 and K-1 II will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

According to Ricoh, Astronomical Photo Assist is a premium feature that must be purchased and costs ¥11,000 for an activation key (about $70 at current exchange rates).

Although these astrophotography features appear to be Japan-only for now, a Ricoh representative tells us, “Ricoh Imaging Americas confirmed that the premium firmware features for the PENTAX K-1 and PENTAX K-1 Mark II will eventually be available to US customers.”

Firmware update 2.50 for both the K-1 and K-1 II is available for download from Ricoh’s website.

On this day 2017: Nikon launches D850


When you use DPReview links to buy products, the site may earn a commission.

As part of our twenty fifth anniversary, we’re looking back at some of the most significant cameras launched and reviewed during that period. Today’s pick was launched seven years ago today* and yet we’re only quite recently stepping out of its shadow.

The Nikon D850 is likely to be remembered as the high watermark of DSLR technology. We may yet still see impressive developments from Ricoh in the future (we’d love to see a significantly upgraded Pentax K-1 III), but the D850 was perhaps the green flash as the sun set on the DSLR as the dominant technology in the market.

Why do we think it was such a big deal? Because it got just about everything right. Its 45MP sensor brought dual conversion gain to high pixel count sensors, meaning excellent dynamic range at base ISO and lower noise at high ISOs. Its autofocus system was one of the best we’ve ever seen on a DSLR: easy to use and highly dependable, with a good level of coverage. And then there was a body and user interface honed by years of iterative refinement, that made it easy to get the most out of the camera.

None of this is meant as a slight towards the other late-period DSLRs but the likes of Canon’s EOS 5DS and 5DSR didn’t present quite such a complete package of AF tracking, daylight DR and low-light quality as the Nikon did. With its ability to shoot at up to 9fps (if you used the optional battery grip), the D850 started to chip away at the idea that high megapixel cameras were specialized landscape and studio tools that would struggle with movement or less-than-perfect lighting. And that’s without even considering its 4K video capabilities.

In the seven years since the D850 was launched, mirrorless cameras have eclipsed most areas in which DSLRs once held the advantage. For example, the Z8 can shoot faster, autofocus more with more accuracy and precision, across a wider area of the frame and do so while shooting at much faster rates.

But, even though it outshines the D850 in most regards, the Z8 is still based around what we believe is a (significant) evolution of the same sensor, and its reputation still looms large enough for Nikon to explicitly market the Z8 as its “true successor.”

Nikon Z6III added to studio scene, making image quality clear

We’ve just received a production Nikon Z6III and took it into our studio immediately to get a sense for how the sensor really performs.

Dynamic range tests have already been conducted, but these only give a limited insight into the image quality as a whole. As expected, our Exposure Latitude test – which mimics the effect of reducing exposure to capture a bright sunrise or sunset, then making use of the deep shadows – shows a difference if you use the very deepest shadows, just as the numerical DR tests imply.

Likewise, our ISO Invariance test shows there’s more of a benefit to be had from applying more amplification by raising the ISO setting to overcome the read noise, than there was in the Z6 II. This means there’s a bigger improvement when you move up to the higher gain step of the dual conversion gain sensor but, as with the Z6 II, little more to be gained beyond that.

These are pushing at the extreme of the sensor’s performance though. For most everyday photography, you don’t use the deepest shadows of the Raw files, so differences in read noise between sensors don’t play much of a role. In most of the tones of an image, sensor size plays a huge role, along with any (pretty rare) differences in light capturing efficiency.

Image Comparison

As expected, the standard exposures look identical to those of the Z6 II. There are similar (or better) levels of detail at low ISO, in both JPEG and Raw. At higher ISO, the Z6III still looks essentially the same as the Z6II. Its fractionally higher level of read noise finally comes back to have an impact at very, very high ISO settings.

Overall, then, there is a read noise price to be paid for the camera’s faster sensor, in a way that slightly blunts the ultimate flexibility of the Raw files at low ISO and that results in fractionally more noise at ultra-high ISOs. But we suspect most people will more than happily pay this small price in return for a big boost in performance.
