An RPL is not a commercial license.

Getting your RPL is not going to magically allow you to fly legally. You're still bound by all hobbiest drone laws. You'll need a commercial license on top of your RPL if you wan't to fly commercially or apply for legal permits.

cool thanks a lot!

Why would you want a 2x zoom on a drone?

If it was something decent like 5x or bigger then maybe worth it but 2x seems a bit pointless.

This is a good question and sure someone more qualified will give a better answer. From a laymans point of view, maybe it's the same thing if you were to hold up a magnifying glass in front of your eyes and run to the nearest store ?

The same reason you would want zoom on any camera, to get a closer field of view without physically being closer to the subject.

With a drone that's very important, as it means you don't have to fly as close to your subject to get the shot you want.

Thanks for stating the obvious but a 2x zoom is a pretty pathetic zoom circa 2018, especially on a drone which is typically a significant distance from the subject.

Hey can you see those ants over there, I mean the humans over there, wait let me activate the 2x zoom - nope still only seeing ants

You can't get much more zoom range on a small drone. The more the image is zoomed in, the more the micro vibrations are amplified and picked up on camera. Any lengthy zoom lens would require a gyroscope for stabilization, which you'll never find on a drone the size of a Mavic. Gyroscopes are also hellishly expensive.

Professional drone pilots know how to get the shots they want, and the zoom is an added tool in their arsenal.

Well thanks for stating the obvious again, who knows what the parameters are that Dji needs to work with, the fact remains a 2x zoom is rather ineffective.

I explained the physical reasons why you can't get much more zoom on a small drone, but you seem completely incapable of comprehending what I said.

2x is like slapping on a 50mm lens. If you know how to fly properly, that's a decent gain.

Unfortunately you haven't mention anything other than your esteemed speculation, no problem with that just don't confuse it with actual facts.

My personal opinion is an optical zoom greater than 2x would be quite feasible on a Mavic sized drone considering how far small form factor optical zooms and image stabilization have come these days. I don't think there would be much image stabilization issues at 5x zoom on a drone, the bigger issue would probably be cramming the 5x zoom inside a weatherproof housing or the battery requirements of the more aggressive image stabilization.

So my esteemed opinion has no bearing? P*ss off.

I work with drones professionally (including working directly with DJI), as part of my job in the broadcast / production industry - but you clearly know better.

You can't get much more zoom than 2-3x optical on a drone the size of a Mavic. It's not a physical size limitation of the compound lens element, but purely stabilisation. They could actually cram a 10x zoom lens in easily if they wanted to.

A motorised gimbal does not smooth out micro vibrations, and these get amplified on zoom lenses, especially with high shutter speeds on CMOS sensors, which the Mavic uses. The Mavic would require a gyroscope in order to support a large zoom range, which is just simply not feasible. Trust me on this.

Always trust an internet expert, they know best.

Maybe back your claims up with links to info that agree with your opinions, that's generally how it's done, lots of shouting on its own doesn't achieve much.

DJI makes a drone with a 30x optical zoom and it uses a high performance gimbal for stabilization. But you clearly know better than Dji and recommend that if they use a camera with 5x optical zoom the camera needs it's own dedicated gyroscope :crylaugh:

The way you are ranting about gyros perhaps you don't realise that all drones incl the Mavic Pro have integrated gyroscopes and a drone with an integrated camera doesn't need an additional gyro just for the camera.

If you want to use an aftermarket camera from a different manufacturer on an industrial or commercial/professional drone then often the camera needs its own dedicated gyro because it can't communicate with the drones existing gyro.

Have you seen the size and price of the Zenmuse Z30 camera? It's an $8000 camera that you need to pair a $5000 drone to get your 30x zoom image.

Also, have you seen the size of the M100 or 600 Matrice drone for the Zenmuse Z30? You can throw an Arri or RED onto that drone.



Get your facts straight, open your eyes and read before arguing.

You are confusing the IMU's gyroscope with a real gyroscope.

I'll say it again;

On a drone the size of the Mavic, you'll need a proper gyroscope to get any worthwhile telescopic functionality, which is simply not feasible.

Bigger drones? No worries mate.

Carry on digging, lol.

All IMU's have a gyroscope, a "real" "proper" gyroscope, nevermind that no drone no matter how small can fly without a gyroscope, beggars belief that you could believe otherwise.

Genetic our bona fide internet professional thinks an IMU doesn't have a "real" gyroscope and believes a drone can fly without a gyroscope, legit totally clueless :crylaugh:

The Zenmuse Z30 is a beast of a camera with a 30x optical zoom and doesn't need a dedicated gyro, you can safely assume a 5x zoom on a tiny Mavic Pro will likewise not need a dedicated gyro to facilitate the zoom.

Nevermind there's no need for 2 gyros on one drone if one gyro can be accessed by both the drone and camera, as I've already explained but don't let logic stand in your way of a good handbag session.

No, an IMU has an electronic gyroscope. A proper gyroscope is mechanical.

I'd love to know where you work, must be an interesting place.

An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes also magnetometers. IMUs are typically used to manoeuvre aircraft, including unmanned aerial vehicles (UAVs), among many others, and spacecraft, including satellites and landers.

If it's good enough for a R500million spaceship it's good enough for my Mavic drone and it's 5x optical zoom.

Just for interest sake you do know that both the M100 and 600 Matrice drones have IMU's?

It's always refreshing when you catch an internet professional out and all they can do is refer back to their own faulty reasoning.

Carry on Genetic, looks like you enjoy pie/making a fool of yourself.
