Hobbyist photographer here and I mainly shoot wildlife. Birds in particular, because we have a lot of birds in Florida. I have the Nikon D500 with the 200-500 mm lens. I have been shooting in Shutter Priority with Auto ISO. It is my understanding that in Shutter Priority, I set the shutter where I want (ie: 1/2000 sec for a fast bird) and the camera will adjust the ISO and aperture. The thing I am finding and find very frustrating is my aperture on the 2-500mm is always at 5.6. Even on bright sunny days. There are times when 5.6 works out great, but other times it doesn't. They say the "sweet spot" for this lens is somewhere around F8 and that would have worked to my advantage recently when I was shooting two Great Blue Herons during their mating ritual, but the camera chose 5.6 so the heron behind the one in front is not sharp. Do I need to take off Auto ISO so the aperture will change? I have tried Manual Mode and in situations where I have more time it works out good, but I'm not experienced enough for the changing conditions that you encounter when shooting wildlife. Any suggestions are appreciated. TIA
