It seems like really bad practice to follow this table. I keep my ISO as low as possible (native or base ISO if possible) and only adjust it upwards if I need depth of field or to stop action that I can't get at a lower ISO. There are many times when I am shooting indoor sports that I need to go above 1600 to get a high enough shutter speed but there are many times you can shoot indoors with low ISO as long as you can either open the aperture up or use a slower shutter speed. This table just seems like you would be losing a lot of DR and introducing noise in a lot of situations where you don't need to.

Thanks my friend for the good reference list! It should come in handy, if I need an idea of what iso might work if needed! :D

I agree.

If you're shooting a static subject, and you've got a tripod, then there's really no good reason not to take as long an exposure as you need to get a good picture with the lowest ISO, and the aperture stopped down enough to get you as much depth-of-field as you need.

All three corners of the exposure triangle involve sacrifice. If you need a faster shutter speed, and a smaller aperture, then you can go with a higher ISO to get that, but my experience,so far, has been that I really don't like the increased noise that results.

Steve & Bob, I agree with both of you. However, it plainly states on the bottom of that chart, that it's only a starting point. Of course, circumstances change all the time, and so do settings, whether they be ISO, aperture or shutter speed. The chart merely gives a beginner a starting point to adjust to as needed. It's not meant to be regarded as being cast in stone.

on top it has M A S P I shoot in A yes auto from 100 to 16oo not max 25600


If you want your minimum ISO to be 100 and the Maximim ISO to be 1600, the go into your Shooting menu.
Scroll down to "ISO sensitivity settings". push "OK".
Set your "ISO sensitivity" to 100.
Set your Auto ISO sensitivity control to "ON"
Set Maximum sensitivity to 1600.

Set minimum shutter speed to what ever you need to have auto ISO kick in.

I can change the min from 100 up but the max is 25600 or higher don't like that

You are either missing a setting somewhere or you have a faulty camera. I would investigate this further.
You might want to do a reset just in case you changed a setting that you forgot about, but I just can't think of what else would cause it not to be able to change the Maximum ISO to lower than 25,600.

Very interesting about faulty camera this is my second D7200. The first one was suppoed to be new but it was used it did the same thing it had close to 400 clicks on it when i bought new from a storel. I think thats just the way the D7200 is made Ive looked all over and cant find any more about in.

thanks for the reply but that's the problem on D7200 I cant get the max of 25600 to change
Are you trying to change the Auto-ISO setting with the large Mode Dial set to either P, S, A, or M? Because Auto-ISO sensitivity options can only be changed in those modes.

See pages 102 -104 of the D7200 User Manual for information on setting and adjusting Auto-ISO options.
