OM System

[PhilM]

I used to retrieve the focus distance from my Olympus EM-1 camera with
 -Olympus:FocusDistance

This does not work with the new OM-1 from OM System

How should I modify my request

Thanks

First check all the MakerNotes to see if it's there with a different name
exiftool -G1 -a -s -MakerNotes:all /path/to/files/

If you don't see any tag that looks appropriate, then there are two possibilities. One, it doesn't exist and isn't recorded by the camera.

Two, it hasn't been discovered. Camera companies don't share data on their proprietary MakerNotes, so any data has to be discovered by the community. You can attempt to see if it is in the file by using the -u (-unknown) option.

First take a picture and take note of the setting. Run the above command but add -u. Change the setting and take another picture. Run the command again and see if there is any obvious change. You may have to do this multiple times to narrow things down.

I have a sample ORF file from the OM-1 that I use for testing and it appears to have the FocusDistance tag - here is a sample from the output:

Code Select Expand

[Olympus]       FocusStepCount                  : 1738
[Olympus]       FocusStepInfinity               : 1006
[Olympus]       FocusStepNear                   : 1639
[Olympus]       FocusDistance                   : 0.7 m
[Olympus]       AFPoint                         : 8522

Problem solved by using the latest Exiftool.exe version.

Maker and tag number and label are unchanged with the new brand.

Thanks for the help
