Hello,

I just relaized that I have an issue with DT detecting the above mentioned 
Canon lens.  

Photos taken until December 2014 show the correct exif and the proper lens in 
the correction modul.

Starting in Jan 2015 (sorry, I do not use that lens very often and do not pay 
attention a lot to the exif and lens correction), the lens name in the exif is 
"(507)".

Whats wrong here? 

The only odd thing I found is that with the old pictures the lens name is not 
left aligned to all the other exif fields. It looks like a preceding white 
space:

Hersteller: Canon
Objectiv:    Canon EF 16-35mm f/4L IS USM
Blende:     F/4.0

Thats all. 

When I compare the exif data of 2 RAw files with exiv2 on the commandline I do 
not see a difference between old and new RAW files. Both show:

Exif.CanonCs.LensType                        Short       1  (507)
Exif.CanonCs.Lens                            Short       3  16.0 - 35.0 mm
Exif.Canon.LensModel                         Ascii      74  EF16-35mm f/4L IS 
USM
Exif.Photo.LensSpecification                 Rational    4  16/1 35/1 0/1 0/1
Exif.Photo.LensModel                         Ascii      22  EF16-35mm f/4L IS 
USM
Exif.Photo.LensSerialNumber                  Ascii      11  2200005331

Any help is appreciated.

Happy new year
Matthias
