Thanks guys
Anthony - I couldnt really do much birds before - so of course this lens is wonderful for me.
It is still a learning curve for me - I listened to Bob as much as I could
Shutterspeed preferably 1/2000 if light allows
F5.6 doesnt leave me much scope - and if the light is not too great, I have to push ISO which I personally dont like much on the smaller birds.
Both my D800's are underexposing - never bothered me in studio - but this actually is huge when you need light
Malachite sunbird - the green one (not shot with the 200-500)
I am sure my set up is not perfect - these birds are small and you really usually need a 600 +TC at least I would think. I have been lucky that I got close.
