camera will maintain the normal range of ISO settings in ISO
sensitivity auto control, so your images will be their normal
low-noise, sharp masterpieces. However, at times the light
may be so low that the ISO may exceed the normal range of
200–800 and will start getting into the noisier ranges above
ISO 800.
Just be aware that ISO sensitivity auto control can and will
push your camera’s ISO sensitivity into a range that causes
noisier images when light levels drop, if you’ve allowed it.
Use it with this understanding and you’ll do fine. ISO 3200 is
the maximum, unless you have set the maximum to a lower
number. Make sure you understand this or you might get
some noisy images.
ISO sensitivity auto control is yet another feature of our
powerful Nikon cameras. Maybe not everyone needs this
failsafe feature, but for those who do it must be there. I will
use it myself in circumstances where getting the shot is the
most important thing and where light levels may get too low
for normal ISO image-making.
Even if you think you might only use it from time to time, do
learn how to use it for those times. Experiment a bit with ISO
sensitivity auto control. It’s fun and can be useful!
