also not sure if you;re aware that this species is VERY difficult to photograph cos they are blakc and white. its very hard indeed to try and expose this right cos the dynamic range in the bird alone is like 12 stops. tough assignment for a brand new lens !
dude i was just so excited i got the lens that i was barely dressed for the occasion LOL!
i was shivering my ass off at that 6 degrees windy cold park!
too bad there is nothing colourful to take pics of yet.
