ISO settings, and other ramblings

As an aviation photographer, It's worth saying that for fast jets etc, I and virtually everybody who shoots planes shoots in A Mode.

That's bizarre.  A mode says your priority is on aperture and you don't care what the shutter speed is.

Ideally we want our shutter speeds as fast as achievable so we are watching constantly what the camera is selecting. If it falls below 1/1000 that may be time to up the ISO, or compromise the shutter speed or the aperture.

So you're setting ISO to get the desired shutter speed ?

Shooting props or for panning we change to shutter priority because it becomes the most important parameter

I get the above mentioned problem when photographing stage scenes. Lighting changes often and abruptly, so M is no choice. So I set F2,8 on the 40-150 and ISO 1600 on the camera in A mode and hope for frozen movements.

I switched brands over 5 years ago to get a camera that offered Auto ISO in M for exactly that reason.  Ice hockey, dance recitals, school plays ... sometimes, I want to shoot wide open; other times I need to stop down a little to get a group of people in focus; for ice hockey, it's pretty much 1/500s or faster, while for dance recitals, shutter speed can vary from one piece to the next.  And lighting varies from one shot to the next.  I set what I need (f-stop and shutter speed) and the ISO is whatever it needs to be.  Why "hope" for frozen movements because of some arbitrary ISO setting ?
