I saw someone flying this gadget yesterday and did some photoshooting too while flying. Did anybody have experience with this flying camera below?

Just in case someone fail to browse the link. I forwarded the review to here

It was less than two weeks ago that DJI Innovations released its Phantom 2 Vision quadcopter, the camera-equipped successor to its popular Phantom model. Since then, I've received a review unit from the company, which I've had a few chances to try out – between snowfalls and high winds, that is. My verdict? It's awesome, despite a couple of surprising shortcomings.




What's new
Like the base-model Phantom (which I'll just refer to as the "Phantom" from hereon in), the Vision utilizes an onboard GPS unit that allows it to hold its position in mid-air, and to return to its take-off point if the batteries in the remote control unit should crap out.

Its big new feature, however, is its built-in Wi-Fi HD video camera – while the Phantom is promoted as being designed to carry a GoPro HERO, buyers of that model still have to supply the camera themselves.

Using the free DJI Vision app on their iOS or Android mobile device, users of the Vision can view live output from its camera as the quadcopter is in flight, plus they can start and stop recording, and tilt the camera up and down. Additionally, the app allows them to monitor aircraft parameters such as altitude, location, and remaining battery life.








Speaking of which, the Vision's other touted feature is an improved 5,200-mAh lithium-polymer battery that slides in and out easily, has a built-in on/off switch, and offers at least 25 minutes of flight time. By contrast, the Phantom's battery has to be plugged into wires that then have to be stuffed out of the way; the only way of turning off the power is to remove the battery; and it's good for about 10 to 15 minutes in the air.

Taking it up
As with the previous model, users still have to go through a little compass-calibration ritual before flying the Vision, that involves holding it out in front of themselves, then turning around in a circle – twice. Throughout the pre-flight procedures, the Vision also still uses different patterns of flashing multi-colored lights to relay its status to the user. Thankfully those patterns are now less complex, plus DJI now includes a little paper card with the remote, which lets users quickly reacquaint themselves with the meanings of the patterns. It would have been nice if that card had been laminated or even made of plastic, but at least an effort was made.

Upon actually getting the Vision into the air, I noticed that it was easier to control than its predecessor. While I first wondered if this could just be due to the practice I got with my original Phantom, DJI informed me that the Vision does indeed use a new-and-improved version of the Naza-M control system.




It also really helps to be able to see things from the copter's point of view, using the app. This is particularly true when the Vision is flying towards you, since the left/right orientation of the joysticks on the remote becomes reversed – if you want the oncoming quadcopter to move left relative to you, for example, you have to push the joystick to your right. By simply watching its onboard video, however, you just control it as if you were in it. This video-watching is made much easier thanks to a smartphone-holding clamp, attached to the remote.

The video feed is also handy for those times when the Vision has gotten far enough away that you can't see which way it's facing. Instead of experimentally turning it back and forth and trying to make out which way it's going, you can just check the view from its camera, and turn it around until you see the desired destination on the screen. That said, don't go relying on getting it back that way – a couple of times when the copter was at a distance, I temporarily lost its Wi-Fi video signal (it has a range of up to 300 meters/984 ft).

Fortunately, you can also use a feature on the app that shows how far the Vision is from you, and which way it's facing. Keep in mind, though, that mobile device screen displays can be pretty difficult to see in bright sunlight. I made a cardboard shade for the iPod touch I was using, yet I still often found it hard to make out many details – such as the locator feature I just mentioned.

Of course, flying by first-person-view is already possible with the older model, for people using a Wi-Fi-equipped GoPro. Which brings us to ...

The camera
I'm impressed with the quality of the Vision's video, and would say that it's on par with that of the most recent GoPro models. It has a 140-degree field of view at its maximum resolution of 1080p (30fps or 60i), although lower resolutions can be selected using the app – it can also snap 14-megapixel stills. The wide-angle lens does present a bit of a fisheye effect that shows up most when panning or tilting, probably to a greater extent than is seen with the GoPro.

A frame of video captured by the Vision's camera

The ability to remotely tilt the camera via its integrated motor is definitely a nice feature to have. With the Phantom, users have to lock in the GoPro at one angle before taking off, then just hope that it will be able to take in what they want when it reaches altitude – unless they're using DJI's new Zenmuse motorized gimbal, that is.

Another great feature is the built-in anti-vibration mount. This uses four soft rubber plugs to (mostly) isolate the camera from vibrations caused by the quadcopter's motors and propellers. Although such mounts are available as third-party aftermarket accessories for the Phantom, that model doesn't come with one included ... and it should. Going with the out-of-the-box setup, vibrations from the Phantom frequently cause what's know as the Jell-O effect – distorted video that looks sort of like it's being projected onto a sheet that's rippling in the breeze. While I won't say that there's absolutely no Jell-O with the Vision's camera, it's definitely minimal.

One thing the camera does not have, though, is a microphone. It could certainly be argued that there's no point in including one, as all that it would pick up would be the whine of the motors and the chop of the propellers. Still, those sounds really add to the "it's almost like I'm up there" quality of the video – without them, users will either have to add their own soundtrack, or just go with stony-silent footage.

Additionally, the camera lacks any sort of line-out port. This means that videos and stills can only be retrieved by Wi-Fi (which involves leaving the Vision powered up the whole time), or by popping out the camera's included 4GB microSD card and sticking it in a card reader. Using such a reader is also the only way of deleting files from the card – it can't be done through the app. This is a bit of an oversight, if you ask me. Fortunately, card readers can be purchased for less than five bucks on eBay (if you don't have one already), although users really shouldn't have to do so in the first place.

It's also worth noting that the camera isn't user-removable. Given that it presumably isn't as rough and tough as the GoPro, it would be nice to be able to take it off for those flights where you don't care about video – why risk the camera and add to the Vision's weight if you don't have to?

Summing up

If you're OK with silent video and buying a microSD card reader, then the Vision is certainly a very nice improvement on the original Phantom. That model is still available, by the way, at a new lower list price of US$479. The Vision, by contrast, sells for a suggested $1,199. It's definitely worth it, although should you already be happy with your existing Phantom/GoPro combo, don't go rushing out to upgrade just for the sake of doing so.

Oh yes, and an added bit of advice ... if you get the Vision, make sure to keep on top of the whole battery-charging thing. Along with the quadcopter's own battery, you will also need to regularly juice up the battery in the Wi-Fi range extender, the remote control unit's four AA's, and the battery in your mobile device.

Cool. I would never own one, but the technology is amazing.

Fun toy, but I would need to have specific purpose for this and I don't. I just saw this one National Geographic show where they were trying to survey this island and they used something like this, and they drone went rogue and they lost it!

One of my friends crashed one of these into a ravine. Considering how pricey they are, he was not a very happy guy. He had a GoPro camera attached to it. We never recovered the footage, but oh man it was sure to be hilarious and depressing at the same time.

Edit: To make this story even sadder it wasn't even his. It was a friend who was a contractor for the military. I should follow up with this friend because I'm sure the story gets worse.

Just ordered this gadget from Amazon over weekends. Can't help with my curiousity after watching so much videos on Youtube and on its official website. Looks easy from what they showing in their videos. Well, let see then, still waiting for the delivery to arrive. :beerbang:

How high will these things fly before you have to worry about it going rogue on you?

You can have live view on your iPhone sent wirelessly from this. I wonder how user friendly that is when flying it around.

Well finally the shippment arrived. Initially I really want to post some photos taken by the camera of this Phantom 2 Vision, however I was a bit busy this week and don't have time to find a good scene for photoshooting. So it is a better idea to share the product photos first at this point.








I played around with the gadget right outside my parking lot a few days back. The learning curve is much shorter than I originally thought of and it took me around 20 minutes or so. It is user friendly enough for adult player to be frank. I'm not that kind of guy to study the user manual but I think the learning curve will be much shorter if I do so...HAHA :lol: The iPhone App not just for taking photos and videos, it can act as a first person view and feeling was just like playing video games, not bad!
