Thanks everyone. I just checked my Lightroom catalog and for the last 6 trips shooting landscape in Italy during 2011 the statistics are the following:
Total shots 7535
Focal length range between 14mm and 35mm (using Samyang 14mm f/2.8, Canon TS-E 17 f/4L or Canon 16-35 f/2.8L II) 9,7%
Focal length range between 24mm and 70mm (using Canon 24-70 f/2.8L II) 34,6%
Focal length range between 70mm and 280mm (using Canon 70-200 f/2.8L IS II with or without Canon 1.4x TC III) 54,8%
The locations were Tuscany, the Dolomites and Abruzzo.
So you can clearly see my preferences
