There are various factors you should take note of when shopping for these particular machines. First, you need to check the control operating system to ensure that it’s easy and manageable to use. Basically, there are 3 main control functions you can choose from which include OPTI, ATTI, and GPS, though they all help in flight-stabilization and assistance they tend to do it in slightly different ways.
Please note that if these drones are flown out of range so that the communication with the drone is lost, the drone can be easily lost as well. A common error is to fly the drone to its height limit and lose communication. If there is any wind, the drone may then do what is called a “fly away.” This is a sad thing for an operator because the drone will fly off to who-knows-where and unless you quickly go chase it; it can disappear forever. 
It's clear from the shorter battery charge time, short flying time, and flying distance of forty meters or less, that the X11 is a drone built for smaller purposes. The forty-minute charge time is perhaps the X11's most convenient feature, as it makes it one of the drones with the shortest charge times, while also able to live up to a comparable battery life of models like the X5C and UDI 818A.

The other primary consideration is how the photos and video are stored after you take them. Drones with WiFi capabilities will work with your mobile device, letting you see and store media real-time on your phone. For those that don’t, you’ll store the media on the drone, usually on a microSD card. If this is the case, know how much storage the drone comes with and whether (and by how much) it can be upgraded.

For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position.  ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.

Most still cameras are 5 megapixels or higher. Therefore, do not be fooled by the claims of HD for a camera when the manufacturer is relying on the resolution for still photos. It is true what they are saying but not the complete story. Having HD resolution for still images does not explain the possibility of also having a lower quality for video-image capture. 
This category is better for those who need drones for commercial reasons, possibly for recording clips for an advertisement or a picture for their business’ profile, for example, or for residential fliers who want the best camera drone on the market. These camera drones for sale are professional in all aspects, with both the camera and the drone being high tech in accordance with the design.

This drone is based on a design that is a few years old, so it does not have an altitude hold function. However, it does feature a headless mode and a one-key return to pilot function. It can also perform flips at a push of a button, which is fun to watch and perform. To help with orientation with night flying, this drone has blue LEDs at the front, and red LEDs at the back.
As it is for every gadget out there, a buyer must set realistic expectations when buying a cheap drone (or other devices).  If you set expectations that are too high, chances of being disappointed ultimately are high, and this may ruin your drone flying experience.  Instead of the high standards, expect far less from the device and let it surprise you instead while providing you with so much excitement in the process.  You may consider buying a spare drone also.
The Altair Aerial Outlaw Drone is one of the best GPS drones around and the absolute best that you can find for under $300. Thanks to the stabilization features in GPS flight mode, this drone will keep itself hovering in midair at whatever place you choose for it to go, making it easy to line up the perfect shot for your photo or video camera. It also has a 1000 meter flight range and a flight time of nearly 20 minutes, which is great for aerial photographers who need time for a longer shoot. If you want high definition, pro-quality photography at a price that won’t break the bank, the Outlaw is the choice for you!
I spoke to these guys when I wrote my complete review of the Altair Aerial AA108 which you can read here. They picked up their customer service phone line on the 2nd ring, which in itself is amazing when you’re talking about drone companies. I’m so used to trying to reach a company only to find out they operate out of China!They have a great product, with specs at least as good as any other drone in this category.
The Holy Stone U818A Quadcopter Drone is our third best drone under $100 for kids with Headless Mode, a return button and low voltage alarm, easy and safe to fly, includes bonus Battery. Remote On the remote control you will find an inversion button that allows you to flip, but you will only want to perform this trick when you are in the air. The control allows the beginner pilot to start flying without much experience, the control, as indicated above, is direct and easy to use. The 4-channel flight allows the engines to adjust and stabilize the helicopter after a gust of wind. The battery of 500 mAh. After the flight, you should be careful, since the battery tends to get very hot; instead, you will have to wait 10 to 15 minutes before removing the battery to charge it. Loading It takes about 2 hours to charge the battery. The 2MP video camera is composed of 720P HD with 2.4 GHz. Reach 30 meters, travel 5-10 miles per hour without worrying about the wind.
There is an altitude hold function that allows you to take aerial shots by releasing the throttle.  Once the throttle is released, the drone hovers in place and take the shot. As a beginner, the headless mode will help you to understand the capabilities of the drone better. Once you’ve gotten conversant with the features, you can do aerial tricks and flips with the drone.
Generally speaking, drones that cost less than $100 bucks aren’t worth your time. They’re flimsy, they lack advanced features, and they’re almost always squirrely as hell in the air. But Tello is different. Despite the fact that it retails for only $99, it boasts a boatload of high-end features and functionality. Under the hood you’ll find a 14-core Intel vision processing chip, flight stabilization tech from DJI, a 5 megapixel camera capable of shooting 720p HD video, and a battery that gets you 13 minutes of flight time.

Even if you have no good reason to justify buying one, you have to admit that drones are cool. Some are glorified tech toys, but most models we highlight here are fit for use in imaging and cinematic applications small and large. If you think you can use a flying camera in your next project, there's some good news—the tech has come a long way in a very short time. There are models on the market now that put earlier copters to shame in terms of video quality and stabilization.
It also can’t handle itself outdoors, with the slightest breeze gusting it away (not only that, but because of how small it is, it’s easy to lose line of sight). Charging takes somewhere around 20 minutes with the usb charger, however you’ll need your own usb to wall adapter or a computer handy to plug it in. Unfortunately, unlike some other quacopters on this list, due to the size and engineering of this drone, repairs are extremely difficult, requiring a very tiny screwdriver to open it up, the solder pads for the motors are also tiny. Repairs aren’t impossible, but it is more difficult.

Want to keep your budget below $300, we suggest you choose one of the Altair drones we recommend. Altair is a great company (learn about Altair) out of Nebraska and provides top notch customer service! Shop the Altair Outlaw which goes 1000+ meters and costs $279. Altair also offers the AA108 as a budget option at $129 and the 818 Hornet is a great mid range for ages 10-14 and $169.

The Holy Stone HS200 is the perfect drone to get started with flying with FPV functionality. This drone comes with many advanced features such as headless mode, and a life wifi camera feed. Headless mode is a good feature for those starting out flying drones. There is also a realtime FPV transmission that allows the camera view to be viewed on your smartphone. The drone creates its own wifi link, so you do not need a separate communications channel.
And now the bad news. You get what you pay for, and if you want an aerial video platform that can capture stunning footage, you need to be ready to spend some cash. Because drones are such pricey propositions, it pays to do your research before buying one. We've tested many of the ready-to-fly models on the market to determine what's important to look for, and the best models available.
To gauge flight performance, we put the drone through a number of tests to see how the manufacturer’s claims hold up. First we take it to a local football field and see how fast it can clear 100 yards, then do some calculations to get an objective reading on speed in miles per hour. After that, we do a similar test to assess ascent and descent speeds, and all the while, we’re also taking notes on how responsive the controls are, how stable the craft is, how far it can go before it’s out of range, and what the overall piloting experience is like compared to other drones.

If a drone in this category has first-person-view (FPV) capability, you can see what the drone sees. All except one of these drones require a smartphone (not included) to be able to view and record the video. The smartphone is held in a bracket and then it is connected to the controller. Some of these drones can be flown by only using the smartphone with a downloadable app installed that controls the drone. 
With an altitude hold mode, which keeps the drone at a specified altitude, the Yanni Syma can hover, ascend, and descend at the push of a button, making this one of the easier drones to manipulate in the air once you get the hang of it. At the same time, the Yanni does have similar downsides in terms of charging time, flight distance, and flight time. It takes over two hours to charge, can travel to fifty meters away, and its battery can last for up to ten minutes of flying time. Even with all of these faults in mind, it would be hard to do worse, considering all that you get with it. Best recommended for the more serious beginner interested in FPV drone racing. 
The other primary consideration is how the photos and video are stored after you take them. Drones with WiFi capabilities will work with your mobile device, letting you see and store media real-time on your phone. For those that don’t, you’ll store the media on the drone, usually on a microSD card. If this is the case, know how much storage the drone comes with and whether (and by how much) it can be upgraded.
Unfortunately, this one doesn’t come with a controller, which means you’re forced to pilot Tello via virtual joysticks on a smartphone app: a control method that’s notoriously mushy and imprecise. The good news, though, is that Ryze built the drone with third-party peripherals in mind, so if you prefer to fly with physical sticks under your thumbs, you can pick up a GameSir T1d controller and link it to your bird. We think it’s well worth the extra $30 bucks!
Many manufacturers mount cameras inside the body of the drone. This is acceptable for casual photography, but if you want more professional results, consider adding an external camera mount, or gimbal. Gimbals allow you to place your video or still camera in front of the drone body, away from the vibrating motor and rotors. Gimbals can swivel and pivot, providing you with additional control over your imagery.
