    Jason ... you can shoot high ISO and definitely reduce the noise by having a decent light source. This allows you to shoot much faster images, too. Everything is a careful balance and that is where you can make or break your shot. Predictability at some level is not always possible. Trial and error take over ... a "manual" deconstruction if you will. Having an arbitrary variable in the situation is not always a good thing.

    theres nothing magical about it, as jason just pointed out to you but you still dont understand. i'm not sure how the auto-iso feature works on an a700 so i'll explain how it SHOULD work.

    shoting in aperture priority:
    step 1: select the minimum shutter speed.
    step 2: select the maximum iso
    step 3: you select the aperture manually

    shooting in manual mode:
    step 1: select the maximum iso
    step 2: you select the aperture and shutter speed manually.

    auto iso always uses iso 200 as its base, so even if you have iso 800 selected as your iso value by mistake, it will drop down to base iso if possible. the iso will only go up to the max you set and will only select a higher iso value IF the exposure requires it.

    its absoultely no different to shooting in aperture priority and the shutter speed auto-magically going up to obtain correct exposure.

    I certainly wouldn't want auto ISO to be the only choice, but I just don't understand why it would be considered a negative thing to have it as an option, in addition to manually setting the ISO.

    i totally agree. we should never be FORCED into something by leaving out the option to turn it off. the issue here is choice. my auto iso is on anytime i dont use flash. i havent selected iso manually for 2 years. that should give you some indication of how much value i put in it.

    Small correction, the base ISO is the ISO value you set yourself. So if you set 400, and your Auto ISO max is 1600, it will not go lower than 400, or higher than 1600.

    in manual mode, auto iso will always drop to 200 regardless of the iso value you set if the exposure allows it.
