native iso is not defined in terms of noise or image quality.
It may or may not be the lowest iso available in a camera.

A true native ISO is only about 4 feet tall when fully grown. The have blue heads when mature and they run around in grass that's about 5 feet tall. If you catch one they sometimes grunt but if squeezed too hard they squeal. Watch out though, if you are bitten you might not live to tell about it.
That's my story and I'm sticking to it. :XD:
The native ISO - bad term - is the ISO level at which the sensor is designed to perform, and is therefore the level at which noise should be at a minimum.
Increasing ISO in a digital camera is done by amplifying the signal which - as with a sound system - adds electronic noise which manifests itself as specks particularly in the darker areas of an image.
Nikon native ISO used to be 200 on older cameras like the D200; today they are set at ISO100.

Hi Linda. It is the best ISO to keep noise lower. Where the sensor does it's best work. Same as when we were shooting film.:) ASA25 rocked ASA400 was for low light. Those were the days!!!!:)

I would say it means that's the ISO you use to get the best possible images, compared with using other ISO settings. Going higher or lower will not improve the quality of the image captured by the sensor.
A sensor's ISO is adjusted by increasing or decreasing the amount of current applied to it.

Jerry: In general, doesn't going to higher ISO (whether native or not) tend to cause more noise...and therefore affect image quality?

Yes, it does. I prefer to shoot at 100 as much as possible. With the newer cameras, you can increase ISO quite a bit and still get excellent results. Better to increase the ISO than get a shaky shot at 1/8 second.
That's more info than I want. :D

I know what you mean about more sometimes being too much, my point was there was no mention of using sensor current as a THIRD method of trimming ISO value.

I have seen somewhere that Canon is supposed to have a native ISO of 160, and that Nikon's native IOS was either 100 or 200 (there seemed to be some dispute as to which was correct). So what is "native ISO", and what significance does it play? Also does anyone know which is the correct native ISO for Nikon cameras, 100 or 200? I did try searching on Google and found some articles that stated Canon native ISO is 100 and that Nikon native ISO is 160, so now I really don't know what is correct. I'd appreciate any help possible.
I have seen the term "native ISO" mentio... (

Never cared what the "native" ISO is on my 7D. I just use the lowest ISO to get the best results that the light will allow.

I think we are beating this ISO to death. ISO being roughly equal to the old ASA rating in film days, the important thing is how high can you go without incurring a little 'noise' that can be easily cloned out, or the maximum ISO above which the noise level is unacceptable and too difficult to fix.
Personally, I set my Canon for a max of 400 but will, when necessary, manually override that up to 1200 and still not get unacceptable noise.

Native ISO, which varies by camera and model, is the lowest ISO setting that is not in the format of "-1". I think of it as the ISO that the camera/sensor was designed to be used at. Anything higher will introduce some level of noise. In the olden days, when using film, one might have a roll of ISO 800 film which was shot with a one-stop "PUSH" to ISO 1600, which was accomplished in the processing. The film, however, had a native ISO of 800. Thats how I think of it. YMMV.
