True, it is still a 400, but the angle of view is an 800, right? So the shake would be moving the lens the equivalent of what an 800 would see on a full frame, right? I am so confused with all this. It is like a 400 with a 2x converter that only sees the center portion of the field.

Still, for hand-held, w/o shoulder stock or pistol grip, I think it's OK! Gives me confidence that when I get out with the birdies (another few weeks, it seems, though the first Canadian Jays, Thrushes and Canada Honkers, not to mention a few Red-winged Blackbirds, are here now), once the backroads are mostly clear of snow, and can use the monopod w/shoulder stock, the results should be quite good. :-) What pleased me is that the focus confirmation worked! Rather well, actually.
