Photographing puppies........ that are really far away.......(Sorry, couldn't resist)

Actually, the longest there is a 400mm, I really don't do much with sports or nature to justify serious glass.

Hmmmm... the image really looks darker here on this monitor.... I'm not seeing much detail in the still cameras..
