M240 metadata

Just got my M240 and have a couple of questions which I haven't found answers for.

1. There is no metadata in the jpeg files. The M8 and M9 had metadata in the jpegs and I use it to search for images with specific data.

2. The ImageUniqueID makes no sense. Previously it was a hex number but in the M240, it's not. It's possible it's octal but even if it is, the images aren't numbered sequentially and the values are way too large.

 

Anybody have any info on either issue?

What metadata are you missing? As far as I can see, everything’s there.

 

2. The ImageUniqueID makes no sense.

The ImageUniqueID is just that, a unique ID.

There is no EXIF, only the file name, file size, dimensions and file date.

 

Are you saying that ImageUniqueID is no longer is a sequential numbering system? If that's the case, why would Leica change this?

The EXIF data is there and all the software I am aware of displays it.

Leica did change a lot. The electronics and firmware of the new M have little in common with the M9 and M8. To quote from the EXIF specification about ImageUniqueID: “This tag indicates an identifier assigned uniquely to an image.” There is no requirement of ImageUniqueID being (or containing) an easily decodeable sequential number.

Exif and ImageUniqueID are still there but the latter does not express the number of shutter actuations any more because it does not make much sense in video and live view modes i've been told. Not a reason to hide it though IMHO.

Then apparently I have a problem because I've checked it in more than one application and it isn't there in the jpegs. Looks fine in the dng's.

If the purpose of the ImageUniqueID is to be worldwide unique, then it must ensure that it is unique next to images generated by any brand of camera. Not sure how this could be achieved with sequential numbers. They probably use GUID to achieve that.

I thought the whole purpose was to have a unique image ID for every image taken by the camera not every image ever taken by any camera.
