Has anyone else experienced this?  To get the most out of the camera, I usually shoot raw, and use AEB for 5 different exposures.  I am getting 2 strange things.  Even though the 5 images are clearly at different exposures, when I upload them to Lightroom and then export to Photomatix to combine, I notice that the exposure data is all same for all 5 images.  Again, this is not correct, because there is clearly a change of exposures in them (I estimate 2/3 of a stop).  
Then, if I use batch process in Photomatix, I get really bad barell distortion created in the merge.  However, if I do it one at a time, there is no problem.  ( When I do this, I do have to hand enter .67 exposure change, because it says the exposure data says they are all the same, again, incorrectly)
Weird.  I called DJI and told them about the metadata issue, and they recorded what I said, they had not heard of this issue.
Other than that, mostly happy with the images.  If you want, I can send images.

You are quite correct, this has been reported before by other users. But DJI do not publicly acknowledge bugs, it loses face.

Sorry to wait so long to reply, I had not checked this forum and missed your reply.  Here is a link to dropbox folder for the raw files, and the result with a batched hdr merge from photomatix.  https://www.dropbox.com/sh/8j5x6 ... yZttvvTTpbsb2a?dl=0

Seems to be an issue with AEB 5 but when I shoot AEB 3 the exif data is correct.

I'm having another unique metadata issue.  The date on my photos is correct but my video files say they were shot in 1950?  Any info on that?

DJI Mindy, I think there more than just wrong metadata, take a look at this post and see more on this issue:

Are they in B&W?

Ditto for 1950's meta in videos.  Exif data for 3 or 5 AEB images is the same except for exposure bias. Very strange way of doing it, and really keen for resolution of this problem.

It's a glitch in the way the exif data is written with raw files.
Shoot an AEB bracket in jpg and everything is correct.

Incorrect dates/time is another glitch that only shows up with some large SD cards.
It doesn't occur with the SD card supplied.

it really needs to be sorted. Relying on jpegs and or the supplied sd card is not viable for 'Pro' use

DJI will fix it some time in the future.
btw the jpg files from the P4pro are very good - much better than most would imagine.
It's not just the supplied SD card that works fine - that's just an example.
