Hi All, I'm using a Nikon d810, and my go-to default setting is to use auto-iso in manual mode. I can quickly change the aperture and shutter speed, which are the most common variables I change when having to quickly pick up my camera and get that moment. Obviously, the camera then sacrifices the ISO to get a decent exposure. For more planned shots, like astro or landscapes, I'll use manual ISO as well, but it's a luxury I don't always have when the kids decide to do something funny there and then. I'm fortunate to use chunky glass f/2.8 stuff (it's good for the biceps at least ) , so it's not often it takes me past iso 3200 which the camera/lightroom can deal with. Finally, the question.... I've read in a number of places I should be using either full manual, aperture/shutter priority and I'm really keen to hear of others experience of auto-iso and if I've overlooked something important. Thanks!
