For an airshow event I took my M9-P and a 135mm f/4 Elmar from the 60's. That was the only equipment option I had so I had to make do! . Weather was constantly changing between very heavy downpours and bright blue sky.
I decided to set my camera only once in advance for the complete display. My settings were:
Shutter: A
ISO : Auto
Auto ISO Setup: Lens dependent (For the first time ever!)
Lens Aperture:f/5.6
Lens: Uncoded
Lens detection: Auto.
I was pleasantly surprised to discover later that every shot was successful and the histogram was consistently bell-shaped and centrally placed. The ISO had always auto selected a setting within the range I set and the images of jet displays are pretty good for a short lens in what would usually have demanded 300-400mm
I don't know if the "lens dependent" Auto ISO setup made the difference, but I seem to have got it just right.
Note: This was a sky oriented event. No ground events. Safety requirements dictated that no planes were flying over spectators and were over the water and at least 300m from us.
Any comments about these settings are welcomed.
