Description Sander van der Heijden 2015-11-05 09:31:08 UTC 
When converting a CR2 image from my Canon EOS 60D to DNG in some cases the ISO speed ratings are missing in the EXIF data. The cases I have found so far are images with ISO speed ratings of 250, 320, 1000, 2000, 2500, 4000. At the URL example images can be found (CR2 with ISO 250 and DNG).

The problem does not occur for images with ISO values 100, 200, 400, 800, 1600, and 3200. For these images the ISO speed rating is present after conversion.

Reproducible: Always

Steps to Reproduce:
1. Select a CR2 image with iso 250
2. Convert the image to DNG
3. Look at the EXIF data of the DNG image

Actual Results:  
Iso Speed Rating is missing in the EXIF data

Expected Results:  
Iso Speed Rating with value 250 should be visible in the EXIF data
