Hello!
Why spending 6000 Euros more for a 200-400mm?
Why to carry 4 kg more with you?
The question is interesting, when you look on the pictures next;
taken the same day - with a little bit more light.
Not all are perfect, but I will show you also the problem with the autofocus,
even with a D3X, the birds are just too fast:
1/400s - f/5.6 - 640iso (autofocus dynamique 51 points all pictures)
even with 1/640 s too slow ....
1/2500 s - f:/5.3 - iso 640
1/3200s f/5.6 210mm
1/400s - f/5.6 - almost, but can you follow this bird with a 200-400?
1/160 - f/5.6 - 640 iso - 300mm
1/400s - f/5.6 - "il y a du mouvement" - this pictures moves...
1/2000s - f/5.6 - couldn't be better with a 200-400mm
1/2500 - f/5.6: birds need this speed
if they don't move 1/200 s ...
1/4000s - f/5.6...all you need is light !
1/640s - not enough to "froze" the bird...
Thanks for your visit and tell me: need or not need spending 6000 Euros more for a 200-400 f/4?
See you soon for some pictures from Switzerland....and China....
