For the past couple of weeks I've been playing with Nikon's D850. It's an incredible piece of equipment! For me, the most impressive take away is how little post processing is needed. Incredible ISO. Acceptable even at 25000...when you have to have the shot. I shoot a lot with Tamron 150-600 G2, and mostly handheld. The image of the pelicans below was
shot at 1/500 at full 600 mm and an ISO 0f 180mm. The image below has been cropped.
