Nice job!

Fwiw, the Olympus 12mm may still be on sale for $100-$150 off list.  I bought mine a month ago at full price and just learned about the sale -- ugh1

I've also found the Laowa 7.5mm a bit fickle at times.  I've seen the exposure to drift quite a bit when changing modes.  One time it took about 20 seconds for the drift to settle down in the histogram before it was reliable.

Too bad DJI doesn't have the means to set non-chipped lenses and add them to the data bank as with the other m4/3 cameras do.  My Pen-F allows me to manually enter the 7.5mm, f/stop, and lens name in memory so the EXIF data is available to the post software for corrections.  DJI should do the same.

Yeah, it is fickle lol, but once it starts working its great!!

Cool, thanks for sharing!
