Armando, the D3S just spoiled me. I could basically shoot at the speeds I wanted knowing that, with that sensor, the images would clean up. Going from D200 to D300, to D700 was a good progression but the D3S was in a different league. I went out again yesterday late afternoon and was paying more attention to the shutter speeds trying to keep the ISO down but 1/1250 is just too slow for many shots. The D500 is very good but I need to be more careful and work on PP for the camera. I did better using the D750. Not much around . The last images shows part of the problem... development in the habitat. Almost all trees, even bushes , have been chopped for cooking fuel.
