Buy a new camera body or a drone?
I already have a Nikon d3200 which is quite an old camera but I have the money to upgrade to a d5600 or buy a DJI Phantom 3. I can't really decide here help
The drone market is plateauing, and restrictions on random free use are growing every day. You really need to research local laws etc, particularly with regard to National Parks and major tourist locations in cities.
Whilst a 5-year jump in technology advancement will offer a somewhat better camera-user experience, the next level of camera (35mm or even to to Sony A7 series ) is where a lot of people decide to make their upgrade to. 35mm in Nikon opens you up to being able to use the manufacturer's top-spec lenses.
So you don't have an easy choice. Use a drone while the authorities still permit it (memorable life experience that no-one can take away from you), a modern version of the camera which you already have, or a pro-spec camera with no limits to your future in photography
Land-shark made a very good observation (darn, a really good one) on drones and laws. Then, depending on where you live and local laws now and in the near future, will also affect how, when, where you use the drone… Not to mention the weather, yes or YES? Well, you can't very well use it in the rain- or snowfall (unless you live in a year-round warm climate area). And insofar as current laws, aren't photographers being hassled even on public sidewalks for photographing what is legally your right, freedom and liberty to photograph even though it is supported by the 1st Amendment of the US Constitution and backed by many Supreme Court decisions because cops are NOT up-to-date or feign to know otherwise to indulge in their ego-gratification routine to harass photographers, adults and teens, using drones (Youtube.com has hundreds of such videoed reports)?
You have a Nikon D3200 entry-level camera; it's a Really nice camera EVEN TODAY. My question to you is, what is it NOT doing that an upgrade will provide you?
Yes, the Nikon D5600 is the most popular mid-range camera today; it is the model number I most recommend. It does the same thing the entry-level cameras do but it's features, functions and options are tweaked to mimic more expensive, sophisticated camera models. My question, basically, is: do you Really need the upgrade? IF SO, have you done your due diligence and done a side-to-side comparison on the Internet? Have you checked the videos on Youtube.com on the Nikon D5600?
Remember, you can use a camera indoors/outdoors and at night or day, but it's unlikely you'll be using the drone indoors or at night. YOU have to make that decision on your own.
Something else. IF you decide to upgrade, I hope you keep the D3200 as either a spare camera or a second camera with a different lens (it's easier, safer t switch cameras than fumble and juggle lenses in an effort to rush and not miss a critical photo opportunity).
And whether you upgrade or not is also a decision YOU alone must make. Here's a piece of gratuitous advice I offer every person buying photo equipment/gear: Buy only what you NEED and WILL use otherwise you'll just be carrying excessive, useless baggage. I hope I've given you things to consider so you can make a more informed decision.
If sticking with your D3200 means missing shots that you'd likely get with the D5600, then it's probably a good decision to upgrade the body. This is especially true if you don't do a lot of video, which you probably don't since you went with Nikon instead of Canon. If the D3200 is still allowing you to get the shots that you want, and you actually have a need for a drone, then go with a drone.
If you just want a drone because it looks cool as opposed to actually needing it, then you may want to consider not getting a drone and just upgrading your lenses. Upgrading your lenses will show a much greater improvement in image quality than upgrading the camera body. And if you upgraded from non-VR lenses to lenses with VR, then the possibility to get even better shots (because you're shooting at much lower ISOs) is going to be an almost certainty if you go with better lenses.
Upgrade your camera body then work on getting lenses.
I consider drones as a passing fad. It is something you might find really fun for a while, but then you'll put the drone away to gather dust.
Photography, on the other hand, can be a lifelong learning experience that never gets old.
Do compare the two cameras in detail. Determine if the D5600 gives you anything you want that you don't have with the D3200. If there's nothing compelling, invest in lenses. Wide angle, macro, telephoto, etc., all open new vistas in photography.
Get the drone.
You know you want a new body when that is all you are asking for.
