"Auto ISO confusion"

Please forgive me but I got confused reading the 7100 user manual about auto ISO. I thought I saw a chart in the manual that precluded the use of auto iso in the P mode. But it does work in the P mode on my camera. Is my camera working okay or did I misread the manual? Thanks Stephen

nope works with PAS and auto. refer to page 81 in the manual.

you can also limit fuctionality on how high it will go. color me stubborn but i keep manual control and adjust as needed. I am going to run some experiments when i have time shooting different ISOs

Thanks. I reread the manual this morning and see the error of my ways. Ten more readings and I may be ready to take some pix!! I limited the ISO somewhat to stay away from poorer quality images. I love that I can pretty much stay away from flash photography: took some great pix at Roosevelt,s boyhood home last week.

I think you will find that if you limit the ISO to 800 maximum, you will be hard-pressed to notice a significant image quality degradation in outdoor shooting even for large prints. I hate to give up too much control to the camera, but I'm coming around to a "corralled" AUTO ISO, as it allows me to keep fast shutter speeds to get the sharpest image without so much manual fiddling. For informal snapshots destined for 4x6" prints or web display only, I have no qualms with up to ISO 6400.

I think if you are using slower non-VR glass using AUTO ISO can make a difference in getting sharp grab shots.

Cheers.

"color me stubborn but i keep manual control and adjust as needed."

Auto ISO also works in manual exposure mode. You get to pick both aperture and shutter speed, the camera adjusts the ISO for proper exposure.

I use this technique for sports. I set the aperture to give the DOF I want (usually wide open for shallow DOF) and the shutter speed to freeze motion. The changing ISO gives proper exposure as a player moves from sunlight to shadow and when a game progresses from daylight to artificial light.
