Yes, this is probably a more authentic description of “native ISO”, but I think most of us consider the ‘base’ ISO as “native” for sensor.

Hello Anybody

“Native” ISO is the lowest selectable value for the camera (usually 100)”

In that location is no specific technical definition of “native ISO”, AFAIK. Information technology’s just a fabricated, oversimplified concept. A camera is actually a list of ISO settings with the associated analog gains, digital gains, and clipping points in the RAW data. Things similar HTP on Canons make the list longer, and cameras tin can practice actress digital pushes for very low f-numbers if the microlens tin’t directly all of the extra oblique calorie-free into the photosites, usually on FSI sensors. This is why noise measurement of a camera should non be done with wide-open up fast lenses attached. f/1.4 lenses will often outcome in exaggerated noise (and reduced DR) that does not apply at f/iv.

ISO 100 clips lower than 200, 400, etc on some cameras, and so should information technology be “native”? Maybe 125 should exist “native”, so, but 125 may be digitally pushed compared to 100, making 125 less “native”.

I don’t know what most people here recall, but that definition Is that of “Base of operations ISO”, but Is Not the definition of “Native ISO”, which usually means the Operating ISO that gives the Best Results for that particular Sensor in that detail Torso, with its associated electronics. This is at least what we employ iwith professional video product cameras.

Mayhap y’all’re looking for more headroom there. Then, it isn’t really “native”, just a good fit to get the headroom.

At present I’ve seen promotional maerial proverb that the 7D MK II’s Native ISO was”100-16,000″ which would exist the ISO range without it beingness extended.

That’s the range that Catechism will associate their name with, implying that whatsoever problems had by going beyond 16K are the users fault for going there.

I’m sure that there is an ISO or ISO Range that delivers the all-time results from a technical standpoint from every unlike Sensor/Photographic camera combination out there. In pro video cameras they just plain onetime tell you what that is and I don’t know why it’s such a chore to find that out for DSLRs??

Information technology is a hollow value fifty-fifty if yous define it. Using the lowest ISO setting and exposing it to the correct will always give the all-time SNR for a low- or medium-DR scene. That does not answer the question of what the all-time ISO setting is for a given sensor exposure, when y’all need shutter speed.

On most Canons, even though ISO 160 has a piddling more dissonance in the brighter tones and mid-tones than ISO 100 (both exposed for the setting), it actually has 1/3 stop less in the very deep shadows, especially with cameras with significant banding dissonance in low-ISO shadows.

I haven’t found what the “Native ISO” for my Canon 7D MK 2 is, so if anyone knows, please chime in

The “native ISO” on my 7D2 is “A”, considering that is where it sits for well-nigh of what I use the 7D2 for.

When light is more than than ample, I switch to base ISO and Av-priority way, commonly.
