Hello,

I think the current 'latest' digital Ricoh GR (2013) is not correctly listed in 'compact-ricoh.xml'. I would provide all the information you need, just let me know.

A 12MB DNG from the can be found here:
https://drive.google.com/folderview?id=0B_T1hFpr9CPffkpGOHhUaHdiaFN5b3NNcXUwTUhESGhmWGpqZk5wbE84bGl5Rk15RWtsNGM&usp=sharing

The output of exiv2 -pt *.DNG | grep -i -E 'lens|model|make' looks like:

0023025.DNG Exif.Photo.MakerNote Undefined 63428 (Binary value suppressed)
R0023025.DNG Exif.Image.UniqueCameraModel Ascii 28 GR
R0023025.DNG Exif.Image.LensInfo Rational 4 1830/100 1830/100 28/10 28/10

R0023026.DNG Exif.Image.Make Ascii 30 RICOH IMAGING COMPANY, LTD.
R0023026.DNG Exif.Image.Model Ascii 64 GR

A Ricoh GR Digital != Ricoh GR (2013).

    Looking at the other bug reports (pmjde*) I think a possible change could look like this, but I'm unsure about the 'mount' and the correct cropfactor (APS-C 23,6 x 15,8 mm). Please fix or let me know what information I need to look up/report. Thanks!

    I fixed it in 023e068.

    Adding the camera prevents some programs from incorrectly taking the GR Digital entry, because Lensfun's name matching algorithm finds the superfluous "Digital" not too disturbing. However, there is still no correction data for this camera of course.

    Hey, I hope it's okay to keep adding info to the closed bug. If not please move/remove. I uploaded a few pictures to:
    http://wilson.bronger.org/calibration
    1fae2a76c558f748ae83bfe9046cea54 RicohGR2013-LensCal.tar.gz

    Please keep in mind that this is my first attempt. I hope that some of the pictures are useful. The weather is bad right now, but I can make more. Just let me know what needs to be changed. I tried to follow:
    http://wilson.bronger.org/calibration/target_tips

    Thanks!

    Update: Something went wrong (I'm not used to using tar anymore, so I guess I overwrote a picture with the tar'ed output). New upload and good error catching!:

    (BTW: calibrate.py needs an update for http://goo.gl/BSARX ;) )
