Ok so I was out testing my newly aquired 2x teleconverter added to my 300mm F4 lens and I duffed this shot by only getting about a quarter of the bird in the frame.
Got me thinking, do we really have to have the entire bird in the frame or does a close up like this work?
Anyways, using the equivalent of a 600mm F8 lens requires a bit of practice to get sharp shots handheld
