It seems that the Exif.OlympusEq.0x0403 tag shows the converter lenses that can be attached to some of Olympus' compact cameras, e.g. the TG-1.
I was able to see three different values:
(but there are likely some others).
The setting is called "Conversion Lens" in the camera menu, so perhaps 0x0403 should be called "ConversionLens".

I'd like to fix this for you - however I'm not sure I've understood what you'd like done. Is it possible for you to provide a patch with the change. You create a patch file with the commands:
$ cd <exiv2dir> $ svn diff > chris.patch

Uhm what I meant was... the tag Exif.OlympusEq.0x0403 seems to be still unknown/unanmed in exiv2.
But I "found" out it's meaning; it specifies the used Conversion Lens, so one should name the tag like: Exif.OlympusEq.ConversionLens.
That's also the name AFAIK, that Phil used in Exiftool, when I told him about this tag.
Clear now? If not I try to write a patch.

I don't pretent to be stupid, it's just that I have a rather small brain. I can see a couple of ways to fix this:
1) If you have an sample image, can you provide me with:
a) your command-line you use to produce it
b) the current output
c) and what you'd like
I think you might have done that above, but without a sample image, I'm not sure.
2) If you succeed in making the patch, you'll get exactly what you want.
#4 Updated by Christoph Anton Mitterer almost 6 years ago
- File images.tar.bz2 added
For now just the description,... I've had a look at the source but it would need me longer time see how to introduce new tags and I'm on a trip for my institute.
Attached are some sample images.
If you do a:
$ exiv2 pr -p a P* | grep CON
you get nothing.
If you do though a:
$ exiv2 pr -p a -u P* | grep CON
P1160115.JPG Exif.OlympusEq.0x0403 Ascii 32 WCON
P1160116.JPG Exif.OlympusEq.0x0403 Ascii 32 FCON
P1160117.JPG Exif.OlympusEq.0x0403 Ascii 32 TCON
you get these yet unknown tags (with the values WCON, FCON, TCON).
What I meant was,... the meaning of these values are conversion lenses that can be plugged on the camera.
So for the benefit of all, Exif.OlympusEq.0x0403 should no longer be a unknown tag but rather be "named" Exif.OlympusEq.ConversionLens.
And the output without -u should give
$ exiv2 pr -p a -b -u P* | grep Exif.OlympusEq.0x0403
If you do though a:
$ exiv2 pr -p a P* | grep CON
P1160115.JPG Exif.OlympusEq.ConversionLens Ascii 32 WCON
P1160116.JPG Exif.OlympusEq.ConversionLens Ascii 32 FCON
P1160117.JPG Exif.OlympusEq.ConversionLens Ascii 32 TCON
Hope that helps,

I'll update the bug report to "Feedback". When you agree that it's been dealt with, please change it to "Resolved". It will get closed when we finish the 0.24 version of exiv2.

Thanks for pointing that out Niels. I've updated the code. r2979 I didn't notice that - thanks for keeping me honest.

#8 Updated by Christoph Anton Mitterer almost 6 years ago
Hey guys :)
Just one thing with respect to the case:
I think it's always good if the tag names are identical to those used by exiftool, which is currently the case right?
I had proposed ConversionLens to Phil Harvey, so he might have used the capital "L"... can you sort this out with him?
#10 Updated by Robin Mills almost 6 years ago
- Status changed from Feedback to Resolved
I'm a little confused (well, I'm often a little confused!).
Chris: I think you're saying that the name "Conversion Lens" is a proposal for ExifTool - and Phil may use a different name when he adds it. I agree that we should be consistent. If ExifTool uses a different name, please update this issue, and change the status to "Assigned" and I'll change exiv2 appropriately.
For now, I've marked this as "Resolved" and it'll be closed during the 0.24 release.
(After it's closed, you have to open a new issue to reconsider the matter.).
#11 Updated by Christoph Anton Mitterer over 5 years ago
I just said he might, in the sense I've had no written contract that he'd use my proposed name ;)
Looking at http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Olympus.html
0x0403 ConversionLens string
So I guess the bug can remain closed.
