LAS VEGAS—DJI has added a new Phantom to its line of consumer-friendly drones. The Phantom 3 4K delivers the same quality video as the Phantom 3 Professional
— that is, 30fps 4K footage at a 60Mbps compression rate—and it looks
almost exactly the same. But while the Professional will set you back
around $1,200, the Phantom 4K is priced at a friendlier $999.
So,
what's missing? The answer is simple one that may be a nonissue for
some and make the drone a nonstarter for others: operating range. The
Phantom 3 Professional—as well as the $1,000 Advanced and pricey Inspire 1 and Inspire 1 Pro
models all use DJI's LightBridge system to stream video back to the
screen of a table or phone. In our tests we've found that LightBridge
delivers solid video streaming at distances of up to 4,000 feet under
the right conditions with the Inspire 1, and about 3,150 feet with the
Phantom 3 Advanced.
The Phantom 3 4K relies on Wi-Fi to transmit the
video feed back to the controller. This limits both resolution—the
stream is 480p—and distance. DJI states that Wi-Fi transmission is good
for a 3,937-foot operating range, but my tests of a pre-production Phantom 3 Standard unit
didn't nearly match that. At its best, in a rural area, I was able to
fly about 1,200 feet away before the video feed started to cut out, and I
only managed 400 feet in the suburbs. Of course, that was a
pre-production unit, and may not be indicative of the final product.
When I flew a production model of the older Phantom 2 Vision+,
which also uses Wi-Fi for video transmission, I was able to go 2,000
feet in a rural area with clear line of sight—still, that's only half of
what DJI claims is possible.
The lack of LightBridge also means that you won't be
able to connect an HDMI device to the remote, so don't expect to use it
with FPV goggles. Aside from those differences, the Phantom 3 4K offers
the same flight features as the Advanced and Professional models. It
supports intelligent flight modes, including Point of Interest and
Return to Home, and has the vision positioning system to help prevent
crashes when flying low to the ground.
It's up to you whether the low-resolution video feed
and limitd control range are worth a $200 savings. But DJI certainly
does offer you options. If you want 4K video and don't mind a lower
quality video feed to aid you while flying, this is it. You could spend
the same amount on the Phantom 3 Advanced, which records 40Mbps 2.7K
footage, and can fly much further, or you can spend a bit more for both
4K and LightBridge with the Phantom 3 Professional. And for drone
videographers who are happy with both a fairly short control distance
and 2.7K video, there's the $800 Phantom 3 Standard.
Pricing is set for the Phantom 3 4K at a reasonable
$999, but there's no word on when the aircraft will be delivered. Like
the other members of the Phantom family, the 4K is heavy enough to
require registration in the United States.
