Since no one mentioned it - Tamron and Sigma both have a 150-600mm lens for either Canon or Nikon that is cheaper (<$1000) and has been getting excellent reviews. They are hand holdable but of course they are a lot more to carry around than a 300 + 1.4.
I can see these are both probably great lenses with a better price / performance balance than the PF, but portability is a key criteria for me - not necessarily really lightweight kit, but compact so I am not carrying round a long lens as well as my binoculars, scope and tripod.
