What would I need for nocturnal photography?
I start my hikes before sunrise. Right now I am using a D500 with a tamron f5-6.3 150-600MM lens. Holding this setup with a flashlight would seemingly be very difficult and the couple of test shots I did seemed to produce very long exposures. I would like to keep the shutter speeds on the faster side, so I am interested in flash with some kind of extender and I wanted to see if someone could make a recommendation. I am not a photography buff so a lot of the details of what would be needed are a mystery to me. For example would I literally fix the flash onto the hotshoe or would I attach it somewhere else? Additionally, should I still fix some kind of spotlight on as well to add with autofocus and tracking between flashes? Finally, how far out can flash throw light? Ideally I’d have a solution effective to 300-400mm if that is possible.
