All
I have a sony Alpha 100 and was wondering what would be the best ISO rate for taking landing photos? dos this all depend on the amount of light at the time of the photo or what would be the best default. I usually leave it a t default levels and the same for the appature.
Any guidance appreciated.

Good advice above . if the light is poor and you have to use a slow shutter speed under 1/300th . than use the in camera image steady shot that this camera model as built in.

It depends on the actual lightlevels and the lens you’re using. To prevent camerashake, a rule of thumb is to use a shutterspeed which at least is 1/focal length; e.g with a 300 mm lens you should use a shutterspeed of at least 1/300 or better even 1/500. With good panning technique it is possible to get sharp shots at lower shutterspeeds, but the above rule is a good starting point.
With fast lenses you can use a larger aperture than with slower lenses. Also most lenses deliver the best optical quality when the aperture is closed one or two stops. So, with a 2.8 lens, you should normally aim for 4-5.6 or better. With slower lenses you’ll normally tend up to use f8. If that’s not possible you should bump up the ISO setting.
For ISO settings go with the rule “as low as possible and as high as necessary”. With your camera I would avoid ISO settings above 400 ISO as much as possible.
