Description

Hello,
My
AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED [II]
is not recognized by exiv2.
exiv2 think it is a:
Nikon AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED

Therefore it is not well recognized by darktable.
I have to manually select the lens from the database (is listed).
I do not know whether lens correction data works.

I guess I should play with the below code lines, but I not so good and would like to avoid doing mistake...

{0x8B,0x40,0x2D,0x80,0x2C,0x3C,0x8D,0x0E,0x01,0x00,0x00, "Nikon", "JAA794DA", "AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED"}, {0x8B,0x40,0x2D,0x80,0x2C,0x3C,0xFD,0x0E,0x01,0x01,0x00, "Nikon", "JAA794DA", "AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED"}, {0x8B,0x40,0x2D,0x80,0x2C,0x3C,0xFD,0x0E,0x01,0x02,0x00, "Nikon", "JAA813DA", "AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED II"},

It could be that the code should be like this:

{0x8B,0x40,0x2D,0x80,0x2C,0x3C,0x8D,0x0E,0x01,0x00,0x00, "Nikon", "JAA794DA", "AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED"}, {0x8B,0x40,0x2D,0x80,0x2C,0x3C,0xFD,0x0E,0x01,0x01,0x00, "Nikon", "JAA813DA", "AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED II"},

But I am not sure! Do you need me to do some tests?

Please find enclosed the output from exiv2 and also Exiftool.

Regards,
Bastien

Hi,
If it can help, and if one of you is not so far away from me, I can bring the hardware so that we are sure to do no mistake.
I live in the North of France, I can go to Brussel, Paris.
Or I can make a photo of my lens also send you JPEG photos shooted with my camera again.
Feel free to ask.

Hi Bastien.

Thanks for your offer, but I live in Denmark, so it is too far away I think. A photo of your lens showing the text on it will be fine. You can attach it to this bug report.

Best regards,
Niels Kristian Bech Jensen

Ok I just made three photos of the lens.
Enclosed are those photos.

I shuld buy an new bleeding edge camera to my parents.
The PENTAX I just used to made those photos is so old and generates so ugly photos. :-/

Hi Bastien.

Thank you for the photos. Robert Rottmerhusen would like to know the serial number of your lens to check against lists of known 'mk I' and 'mk II' lenses. Could you add that number?

Best regards,
Niels Kristian Bech Jensen

Hi,
Thanks for asking. I appreciate that you are sensitive about "privacy" and such matters regarding the photos.
You can use as you want, without any restriction.

I am really happy because I have help to fix a problem.
Thanks a lot also to you two for your fast and effective support!
