Originally posted by Pål Jensen Never heard about dawn or dusk wildlife photography. Where are such images published? Dusk is not popular time to wildlife photography and never heard about any wildlife photographer who do so at any significant extent. It is another of those armchair argument with little bearing on reality. The ones I've seen are shot with manual focus (film) cameras at low ISO with flash. 800ISO is plenty enogh for wildlife photography....
First, my lack of coherence on that point has to do more with my lack of english proficiency. I though that dusk and dawn were the hours prior and after the sun sets or rises.
Second, If you dont see the utility of going beyond 800 ISO for wildlife good for you. I am sure that you have NEVER lost a decent amount of shoots due to low shutter speed in those conditions. I am sure that shooting in shade, a forest or under a cloudy sky never happened to you. Unfortunately, I am affraid that you belong to a select group of photographers that can do marvels with lesser equipment. I barely see how that rate as
most of us
Third, an armchair is a nice place to be. I wish I could be there more frequently.
Fourth, I am counting the seconds to have the arguments of how in the hey days nobody used high ISO obladih-obladah.
EDIT
Note that I am not saying that other APS-Cs perform better. I am just saying that from a reviewer point of view, high ISO might be as a important for a given reader, as using SR, VR, IS instead of a tripod, or 2 wheels to change settings, or to have mirror lockup functions, or multiple exposures, HDR in camera, AF, a sensor, a shutter, hot shoe, pop-up flash, custom settings, etc, etc, etc
