I'm using a Konica Minolta Maxxum 7D camera. When I run exiftool on my jpeg or raw image files there are a number of tag data items that do not have values. For example:

DriveMode
FocusArea
FlashFired
FlashExposureComp
FlashMode
FlashMetering


There are probably others, but these are the ones I quickly ran across. These are listed in the list of Minolta tags and specifically for the 7D. All are basic information, so I would be surprised if Konica Minolta excluded them intentionally.

Does anyone have an explanation of why I am not seeing these? Is the data really not provided?

Thanks.

Hi Jeffery,

There is certainly a lot of Minolta maker note information that is still unknown. Anything you could help decode would be useful. You can use the -U option to display the unknown information. All of the Minolta tags currently decoded by ExifTool have been discovered by other Minolta owners.

The tags you mentioned (DriveMode, FocusArea, etc) are used by some Minolta cameras, but haven't yet been decoded specifically for the 7D (See Minolta CameraSettings7D tags for a list of tags specificallyl decoded for the 7D).

LightSource is a standard EXIF tag (use the -G option to see where the information is extracted from), and a value of 0 is defined as "Unknown", so this is what is reported by ExifTool. If the Minolta software reports something else, then they must be getting this information from some of the unknown information in the maker notes.
