Just thinking this over, i've a D750 which by all accounts is a quite capable camera, but all i ever do is stick it in Aperture priority, single focus point that I move around if need be and manually adjust the ISO to something if i think i need more speed. And that's it. I think im missing out on about 70% of the camera's capability. I know there are some cool focus modes which would help when trying to shoot my sisters kids when they're tearing around the park but i haven't read up about them yet and the auto ISO think sounds good. There is bound to be some other options in there which would be useful but i've never really sat down and read the manual. I think its mainly down to being predominantly a film shooter with some quite aged gear and i use my Nikon in the same way i use them. Anyone else feel like they're not really using the gear to the best of its ability?
