Is the Mini your only DJI drone?  If so, you should really consider a Mavic Air 2.  Seriously, if you enjoy the Mini, you will absolutely love the MA2.  Takes things to an entirely different level.  Hard to believe what you get for only $988.

What? If you check my details, you should find that I have had the MA2 for months now and have posted many, many times in the MA2 section including videos.

Maybe you should re-read my post...for comprehension this time.

I’m pretty good at comprehension according to my daughter! You said “ I am biding my time before expressing any disappointment with either of mine.” which, to me at least, implied that you may express your disappointment at some stage but just not yet. I’m very happy with my Mini - it does all I expected it to do (and more, with the latest 3rd-party apps). I had no expectations of it doing anything other than what DJI said it would. I might outgrow it but I can’t see me becoming disappointed with it.

How about, RAW has far more data to be handled, requiring additional processing power / time.  The RAW data has to be buffered out through hardware for microSD card.  The additional buffering would take processing time away from flight critical processing time.

The RAW data is already being handled in the creation of the JPEG.  If recording the sensor data for a photo is too taxing, then recording a video stream would not be possible.

I have no real disappointments AT THIS TIME. I do notice that it takes the Mini far longer to acquire sats than the MA2. I would have assumed the same GPS engine is used in both. But maybe not, or the antenna is just bigger.. As implied, only time will tell what drawbacks are significant and lasting. There are revisions almost every week to the app or the drone, so it makes little sense to pass judgement now.

As for this remark: " If you hadn't previously had a drone you would have had no expectations about what it could do.", I pretty much said the same thing in my post, hence the re-read suggestion. " But with the Mini, a whole new group of novices has emerged (like me) who have no field of reference regarding drones at all"

Sorry haven't frequented the MA2 until recently.

Recently huh? Does that mean you are planning to buy one? I can definitely recommend it.

What you are missing is additional processing load and processing time of writing RAW data out to controller for microSD card.  Which would be in addition to JPEG data which has to be buffered and transferred to drone's transmitter to be sent to SmartDevice.

As another poster pointed out, the processor is already being pushed hard without normal heatsink and cooling fan, present in other Mavic models.   A trade off to keep weight down.

You keep ignoring the fact that the volume of data written to the card during the recording of video is orders of magnitude greater than that of a single photo.

Since you want to factor in processing overhead, consider what it takes to stabilize and encode video, vs. reading RGB values directly from the camera sensor.  There is no additional processing in the pipeline that writes RAW image data to media storage.

No disrespect, but I think I'm done discussing this.

I think what he is saying is that it takes longer to write the larger file and that takes up "processing" time. Computational time is small compared with storage time, especially to a serial interface memory device like an SD card.

Thank you for your more precise answer, I now understand better there are material limitations and not software.

You are correct, my thinking about Raw and this drone is dji decide that Raw was something it would not offer in what is essentially a drone for first time users. Less complications and other drones cater for this. Many camera brands particularly cameras for first time users don’t offer raw as a feature, so I believe there is nothing unusual about this, but as photographers want to expand they upgrade their cameras and thus this is how marketing gets a hold of people.

I don’t have another drone to compare it to, but my Mini has so far always had a GPS lock before I’ve wanted to take off without me having to wait for it.

As for my comment about expectations, this thread was about supposedly missing features in the Fly app and the Mini/MA2. A beginner with no previous drone experience wouldn’t assume that there was anything missing after reading through the relevant pages on the DJI web site. Both drones do all that DJI claimed they would. It’s only those with more sophisticated drones who would complain that certain features were “missing” from the Mini and the MA2. If those features were never specified or promised, how could they be missing?

even if I will say nonsense, but if with a disclaimer, to be selected in the app, a user takes the risks, relieving DJI of any responsibility, it may be possible to provide the active track , follow me and waypoint. 499 euros is not very cheap for a drone, even if of DJI quality. I hope we can soon have a more productive drone and not relegate MINI to the role of Fly Cam. I will also buy a Mavic Air 2, because I think it's great, but I'll wait until I learn how to fly well with the MINI

I agree.  The feature isn't absent due to any hardware limitations.

I purchased the mini because it is small enough that I can keep it in my pack and have it with me at all times.  As a photographer, not having RAW is a real bummer.  I'm hoping that DJI will someday reconsider their decision to exclude it.

I understand what he is saying, and I agree that it takes longer to write the RAW file than it does a JPEG.  But the amount of time it takes to write a single RAW photo is negligible when compared to writing a 2.7K video stream @ 30fps.  That's all I'm try to say.  I do appreciate you trying to help.  Thanks.

"reading RGB values directly from the camera sensor"

RAW image data is not  RGB values directly from the camera sensor.  There still is processing done, albiet minimal, prior to data being written in RAW format to a file.

Yes.

Have also seen issues where write speeds to one type of device is significantly impacted when another different type of device is written to at same time.  Double issue.  Contention for buffer space, and one device needing to be fed byte by byte (burning CPU cycles), whereas other device was fed 4096 bytes (or more) at a time.  

Regardless, of whether or not Mavic-Mini has capability to handle RAW without negatively impacting MM, is expecting to much from DJI to add RAW capability as firmware update.  Had DJI advertised or marketed MM as having RAW capability or promised RAW capability in X months after initial release, it would be totally different matter.

It's absolutely doable with a firmware update.  Hopefully we will see it someday.

It must be .. I read it somewhere on a forum.
