Just read a piece saying that with the D750 on auto ISO you can set it to take into consideration the focal length you are using say with a zoom,so decide the min shutter speed you want to use at a given focal length,can any one confirm this.
As far as I know based on my experience with my current equipment, the auto ISO works and adjust the settings in order to create a well exposed image based on the metering, Aperture, and shutter speed. The focal length factor is news to me but then again, I have not been current with all of the latest technology.
This was one of the features that convinced me I needed a d7100. So yes, your d7100 has it.Yes,i use auto ISO on my D7100 but have not seen anywhere that will automatically adjust the shutter speed for a zoom,but this guy had said the D750 will do that.
I'm pretty sure the d7000 does not have an auto setting for minimum shutter speed under auto iso. Just throwing it out there in case somebody deciding between a d7000 and d7100 reads this.Auto ISO will always consider focal length on every Nikon I've used it on provided that the lens actually communicates with the camera. That includes the D7000, D7100, D600, D610, D750 and D800.
Under the Auto-ISO function there is an option to adjust the minimum shutter speed; I have a feeling this is what the article is referring to. You can set it to use a specific minimum shutter speed (say, 1/125 or 1/60 or 1/1000 or what have you) or you can set minimum shutter speed to "Auto". Under the "Auto" selection this a slider that has five settings from "Slower" to "Faster". Typically, I shoot in manual mode with Auto ISO enabled and the Minimum Shutter Speed option set to "Auto" with the slider moved one click towards "Faster".
This is how the D750 is set up and I'm 99% sure the D7100 is set up the same way. I'll go get my 7100 and check, though...
Yup, the D7100 has the same menu options for Auto ISO as the D750.

I set it to the +2 side of faster and almost never use VR any more. The only time it will not adapt is if it cannot produce a proper exposure with your camera settings and the max ISO you've directed it to use.

I don't really understand the focal length part.
If I set auto-ISO I can define the minimum shutter speed I desire and the maximum ISO to be used. That's it.
I had never ran the full list of minimum shutter speeds on my D7100 but if you do you will see "AUTO" at one end. This sets the shutter speed based on the focal length supposedly. I have been trying to find the parameters of what it sets based on the focal length but have not had any luck finding it yet.
Horoscope Fish is correct in saying: "Under the "Auto" selection there's a slider that has five settings from "Slower" to "Faster".
If you select the center mark (default), then the minimum speed is reciprocal of the focal length (for example: 1/100s for 100mm lens), each mark in either direction from the center is roughly one f-stop faster or slower.
I played with it this afternoon and that is roughly what I found.
Enlighten me if you want since I might have to shoot the D810 using ISO.
I assume this shutter option has some advantage when shooting auto-ISO in A mode?
