SIZE ... Does it really matter?

I liked this shot as it did not reveal who the photographer (person) was, and, as I set up for this, he abruptly pulled back the 400mm lens over his shoulder and used the 70-200mm lens instead. Hence the question: Does size really matter? This can be interpreted in many ways.

From afar (across the field), I thought this photographer was using a

Canon 600mm lens. Just the same, he was using a nice 400mm f/2.8

with a 2x TeleConverter. Nonetheless, this is submitted for those

that work hard, carry those large-heavy lenses and capture those

amazing images. Critiques and comments welcome.

A really beautiful shot, well seen, Stephan!

size does matter. however i'm not sure of the journalistic appeal in a guy with a 70-200mm with a 2x and a 400mm with a 2x?
