Is it possible to disble auto focus

Hello Zane et al.

Is it possible to set a DJI Mavic 2 Pro autofocus to manual in DJI Go 4 app and then go to Map Pilot keeping that setting?

In other words, is it possible to lock the Mavic 2 Pro in manual focus to ensure that Map Pilot doesn't make changes to the preset focus setting?

I would like to avoid Map Pilot to focus at the beginning of every flight.

Thanks and best regards

No , but by default, the whole flight uses an autofocus solution that is achieved at the top of the climb from the home point to the cruising altitude. This is using the same autofocus that DJI Go uses but to be honest it is prone to failure if a good solution cannot be found. If the focus target is bad (low contrast, different altitude than the eventual target), the solution will be bad. 

At any point during the flight you can stop by hitting the 'Stop' button and then do a double tap on the area of the camera feed where you want the autofocus to be done. Choose an area of high contrast for best results.

Im using this method (Manual focus in DJI GO4 and no focus:infinity touching in MapPilot in Phantom 4 pro) now, but why you cant use this method for M2Pro?!

I wouldn't think that would work at all anyway but if it works for the P4P it should work for the M2P. There isn't any difference it how it is focused depending on the aircraft.

I am using a PPK system in Phantom 4 pro!

I need a fixed manual focus in 150m flight height for 100 missions!

but map pilot will make autofocus at the beginning of all flights!

The autofocus will change elevation accuracy in each mission(flight) and this is not good for a PPK drone like Phantom 4 Pro or Mavic 2 pro!

I have a solution for disabling autofocus in beginning of the mission but I don't try this solution yet!

I think If I turn off RC, MapPilot can't send autofocus command to the drone and the drone will use DJI GO manual focus setting in that mission. You can turne on RC after when the drone moved away from you 100 meters.

Is that right Zane?

If you're mission (s) is at 150m ag, then that is the altitude that the focus will happen.  It climbs to mission altitude and then pulls focus. Why do you say that it will be the incorrect focus height for the mission?

While I have not tried it, I don't think the MP mission will continue unless in connectionless mode if you turn of the TX (RC).

You can also quickly pause the mission over a high contrasting area of ground, tap to focus and then continue.

The only way to get a repeatable focus value would be to set it to infinity which basically just puts it at the end of the range for that aircraft.

The answer was provided 15 days ago:

"The only way to get a repeatable focus value would be to set it to infinity which basically just puts it at the end of the range for that aircraft."

Flying while using multiple apps is a great way to make your aircraft fly far far away...

Sometimes Focus:Infinity botton in MapPilot is confused and has bad results or even reverse direction to near focus! I tested in some drones. Sometimes good sometimes very bad.

We need a fixed focus in all of missions!

If I touch Focus:Infinity in first flight,Map Pilot will set focus toAF automatically in second flight and I must touch again it to infinity in MapPilot camera setting and Must touch for all of flights in a big project!

If tapping to focus once per battery is too much work for you, flying drones is probably not for you.

My insistence on removing or selectable AF feature was not that I should not do repetitive work for touching on infinity botton!
I mean, I decide for myself where to focus, and because good focus is not always up to the end of the infinity icon, and sometimes it has to be adjusted to the last line near of infinty icon.

Anyway, I love this app. Especially in the mountains and in places where we need to fly at variable altitudes(3D fly).
But if MF be better and use DJI go focus setting, which in previous versions sometimes used DJI GO focus but in this version 4.1.13 always autofocuses at the beginning of the flight, I and many of my colleagues here who have Phantom 4 pro PPK or Mavic 2 pro PPK do not like it.

Automatically switching to AF is not good for DJI PPK drones but it is good for original DJI drones without PPK.

DJI released a camera called P1 for M300 with fixed focus! why? for preventing height error in drone mapping.

So please add a item for using a best manual focus in next version. Because my projects has big error in Z axis and this is bad for Map Pilot and me and other surveyours with a PPK drone.

1- Please add an item in the setting to use DJI GO focus setting

2- Remember last flight focus AF or MF and dont set AF automatically in the beginning of flight and show a graphical tool like DJI GO for changing manual focus value( like this image)

If we make any changes it will be in our Map Pilot Pro app that is coming out soon.

Long ago, I suggested the same.  That is, an option for "use DJI GO settings".  When set, Map Pilot would simply read the settings from the aircraft and use them.  That option has never been added.

So, we work around.  In my first reply, I told you how you can reliably set the focus every time in Map Pilot.  Start the mission, let it take off and climb to mission height.  Pause the mission when the drone is over a sufficiently contrasting subject, tap to focus, un-pause and continue. I usually use a P4P and get consistently good focus with this method.  Letting MP set the focus is hit and miss as you have found.

It would be nice if MP had the setting to pass-through settings, but right now and perhaps forever, that is not the case.  The method I suggested does not take much effort to ensure good results IMHO.

Ok. Thanks. I will wait for it.

I hope add at leat a new feature for manual focus.

We have no plans of supporting a setting to allow for setting the camera up in another app. We may add a focus ring slider to allow for repeatable setting of the focus value. Maybe. We don't want people switching back and forth between apps in flight. You should see some of the emails we get...

There is no doubt lots of folks do stupid things with dji drones because they are so easy to get in the air,  Why learn, right?

"We don't want people switching back and forth between apps in flight."

Zane, I know you are aware that the camera, as well as most craft settings are saved on the craft.  When you start the craft using Map Pilot, all of the users defined settings persist....until Map Pilot overwrites them.  If you were to simply NOT overwrite the camera settings, for example, then there would be no need for a user to open GO first.  Map Pilot would simply be using the camera settings last set in GO.  I'm not sure why DME insists on catering to the users with the lowest knowledge of the tool they are using.  I think Litchi is probably the most prolific sdk app and has no issue reading the settings from the craft.  Perhaps after the "pro" version, you could release an "ultra super user" or whatever you want to call it, version for folks that actually know how to use the craft.   You could require an online quiz ! :D

After all these years and countless flights that people will have had ruined by the insistent use of an autofocus system, the thought that the option to toggle focus like the dji go app is still being debated is unreal, if you're going to stick with the 2 finger tap to focus at least have a little pop up confirming focus was reset, got majorly burnt with this on a job and every time i need to use MP compared to say dji gs pro I'm anxious the entire flight in case I need to refly it due to poor focus.

Cameron: The infinity focus option has been there for a few years. And when you do an autofocus manually there is a popup that tells you if it was successful or not. This popup only tells you if the DJI SDK function that was called says it was successful though. It does not tell you that the autofocus is actually any good. This is why we added the capability to redo it in a contrasty location that has a higher likelihood of being a quality focal fix. We have added a manual focus capability to our upcoming Map Pilot Pro app.

Whilst infinity focus is there, infinity focus isn't always the sharpest, especially flying low or with a wider open aperture, hence the desire to refocus and lock it off. I can't say I've ever seen a pop up after the 2 finger tap to refocus or heard it make a noise to indicate it. I look forward to the pro app, are there any details on costs, functionality and release date?
