Came across this interesting short video, persumably by Canon personnel.
It compares some common canon primes, L and non-L, with the subject staying still and the video appears not to have received too many hits, so I wanted to share for those who may have missed it.
It is charming if you are a jaded, cynical old hand and highly informative for the newbies who don't have a feel for what it looks like through the view finder with various lenses in one go. Ah..hem, I found it charming
In passing, I notice he stays at ~near minimum focusing distance for 85 f/1.8, 85L, and 135L generating interesting FOV comparison: http://m.youtube.com/watch?v=vC0yvuXnRN4
