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:
even with 1/640 s too slow ....
1/2500 s - f:/5.3 - iso 640
1/160 - f/5.6 - 640 iso - 300mm
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....
