Goldfinch male serenading the ladies

With a little more tweeking of the auto focus settings on my D800 I think I have actually got it as good as it's going to be with the Big Sig.
    Pretty much spot on now I think?
Goldfinches have made it an entertaining afternoon in the garden.With the courtship flights and  aerial acrobatics.
   And the ''Song''! Well they never shut up.They are so excitable!
