optimum ISO setting best for low noise, maximum dynamic range and colour saturation

[GrashamR53]

Many professional photographers state "use the lowest ISO possible" for optimum  low noise, maximum dynamic range and colour saturation  when taking photograph still images,  but that is not always possible in low light conditions.  What range provides the optimun performance on my A77II DSLR which has a 24.3MP APS-C CMOS sensor?

Hi there,

Welcome to the Sony Community.

I'm looking into this for you and will come back with an answer soon.  In the meantime perhaps another user in the community may be able to help.

Best wishes,
