Goldfinch comparison

Nothing scientific but I had a cooperative bird stay in one spot while I switched lenses. So I did quick comparison with this Goldfinch between the 400mm with the 2x and 600mm with the 1.4x handheld in the 800mm range. The 600mm wins but not by much. I have both pictures posted alone so you can view them larger.
