Aha, he who searches shall find ... at least if he uses the shell:

So an analysis of which focal lengths are used how often is quite easy:


$ exiv2 -g Exif.Photo.FocalLength *CR2 | cut -b 82- | uniq | sort -n | uniq -c


4 24.0 mm


1 27.0 mm


1 28.0 mm


1 34.0 mm


3 35.0 mm


1 45.0 mm


1 48.0 mm


6 50.0 mm


8 70.0 mm


1 85.0 mm


1 97.0 mm


1 127.0 mm


1 135.0 mm


1 173.0 mm


7 200.0 mm
<div></div>

Perhaps this is more useful:


&gt; exiv2 -g Exif.Photo.FocalLength -g Exif.Canon.LensModel *CR2 | cut -b 83- | streplace -x " mm\\n= mm " - | uniq | sort -n | uniq -c


4 24.0 mm EF24-70mm f/2.8L USM


1 27.0 mm EF24-70mm f/2.8L USM


1 28.0 mm EF24-70mm f/2.8L USM


1 34.0 mm EF24-70mm f/2.8L USM


3 35.0 mm EF24-70mm f/2.8L USM


1 45.0 mm EF24-70mm f/2.8L USM


1 48.0 mm EF24-70mm f/2.8L USM


4 50.0 mm EF24-70mm f/2.8L USM


2 50.0 mm EF50mm f/1.8 II


5 70.0 mm EF24-70mm f/2.8L USM


3 70.0 mm EF70-200mm f/4L IS USM


1 85.0 mm EF85mm f/1.8 USM


1 97.0 mm EF70-200mm f/4L IS USM


1 127.0 mm EF70-200mm f/4L IS USM


1 135.0 mm EF70-200mm f/4L IS USM


1 173.0 mm EF70-200mm f/4L IS USM


7 200.0 mm EF70-200mm f/4L IS USM

Oops, the first invocation to "uniq" is of course one to many, only the finaly uniq -c must stay.

Since I use Lightroom 3 anyways, I use Lightroom to read out the EXIF. It looks like this:





And you can adjust it by your own wanted specifications.


Good luck,
