Yes, I double checked and quotes are needed, at least on the command line. According to Phil Harvey, double quotes are required for windows, double or single will work with Mac.
Regarding the GUI, I would absolutely love to be able to use it, unfortunately it's for Windows only
Thanks again, you've made this lens a lot more enjoyable to me.

Great thread !
My 8-16 is in the post
Are LR and PS the only programs that correct at 8mm ?

all a moot point as the 8-16 is still in the post...I think they are making it especially

This post inspired me to make a batch file which, since I have found it to be quite useful, I thought I'd share here.
Assuming you already have created/edited your .ExifTool_config file as described by the OP, you can put the following into a file called something like "Process_8mm.bat"

O:\Photography\Utils\EXIF\exiftool -progress -overwrite_original -k -ext dng -ext pef -r "-exif:FocalLength<copy2:FocalLength" "-exif:FocalLengthIn35mmFormat<Calc35mm" -if "not $FocalLength ge 10" "%1"

Now you can drag and drop either an individual file or a folder full of files onto this batch file. All the parameters are documented in Phil Harvey's Exiftool onboard help listing, but here's a rundown.
Only PEF and DNG files whose focal length value is not greater than or equal to 10 (meaning <10 or missing) will be affected, no backup will be created, and the output will be displayed for your confirmation.

Hope this helps someone.

Hello,
I'm very interested in your batch file, but I'm not able to let it work...Since I'm computer illiterate, could you please help me?

I followed these steps:
- put exiftool.exe into d:\Program Files\Utility
- created in the same directory .ExifTool_config file
- pasted into .ExifTool_config the following lines:

%Image::ExifTool::UserDefined = (
'Image::ExifTool::Composite' => {
Calc35mm => {
Require => 'copy2:FocalLength',
ValueConv => '$val * 1.5'},
},
);

- created sigma8.bat in d:\Program Files\Utility
- pasted in sigma8.bat your line:

d:\Program Files\Utility\exiftool -progress -overwrite_original -k -ext dng -ext pef -r "-exif:FocalLength<copy2:FocalLength" "-exif:FocalLengthIn35mmFormat<Calc35mm" -if "not $FocalLength ge 10" "%1"

- dropped a folder containing 22 DNG files (1 taken at 8mm.) over sigma8.bat
... nothing happens. the DNG taken at 8mm. has an empty field for focal length
What did I wrong?

Assuming you already have created/edited your .ExifTool_config file as described by the OP,

Who/What is the OP?

Can I use your bat file in ExiftoolGui (much more user friendly)?

Thank you.

I haven't tried ExiftooleGui so can't advise you on that one.
I think the problem you are having with the batch file is because your path to the exiftool program has a space in it so you will need to put quotes around it like so:
"d:\Program Files\Utility\exiftool" -progress etc...

You're correct! Now it works.
Many thanks.

Hello!

One question: Does this workaround also work after an update of Lightroom or Camera Raw or must I repeat the steps after each update?
Thanks.

Thank you for this information!
Unfortunately my workaround don´t work: Changing metadata with exiftool and the .bat works. After I have reimported the pictures into Lightroom I actualize the metadata an the right focal length is displayed.
But when I want to start the lens correction it doesn´t anything happen (with pictures <10mm). With pictures >10mm the lens correction is working fine...
Does anyone know what I have to change?

[cali92rs]

Has anyone used this lens with the DxO module...apparently it is supported now? Do yoh still have to modify the exif data?

you don't seriously expect Pentax to help out a competitor do you

hehe that sounds like something Tom or Greg would come out with...
