D800 Vs. D810 in regards to ISO

[Trever1t]

With the new 810 the native ISO is 64 in comparison to the 800's 100. The range of the 810 being 64-12,500 and the 800 at 100-6400. Now I'm not really sure what exactly that means. Why the lower native ISO, what are the benefits? Doesn't that top end loss (limit of 12,500) mean that the 800 is actually more usable in lower light circumstance?

Is that right? If so, does that ISO64 make the loss worthwhile at the lower end?

Lower than 100 ISO is great for shooting wide open during the day (1.4, 1.8, etc), or for landscapes shots when I want a longer shutter. Today I used low 1.0 (which is ISO 50) so I could get a longer shutter speed than at ISO 100. A second or two difference can really change a flowing-water shot. So, to me, lower native ISO is a good thing. I rarely go above 6400 anyway, so high-end doesn't matter too much to me.

You confoosed me... the D810 has a range of 64 - 12,800 vice the D800's 100 - 6400. Doesn't that mean that the 810 wins on both ends (Lower low, higher high)? A lower base ISO would be beneficial in terms of dealing with very bright situations as well as lower noise images.

And from what I understand, the D810 has better higher ISO performance, and is MORE useful in low-light.

DOH!!! omg, how do you know when you're tired? Ans: When you can't figure out 6400 is less than 12,800

Going outside of the native ISO ranges comes at a cost in image quality. Going below lowest native ISO will cost you in dynamic range while going above will cause excessive noise. The Nikon D810 will have a wider range of useable ISO.

LOL!! Foshizzle!

Back when I had my little S3IS, it went down to 50 ISO, and I learned that it was useful for very bright conditions.

64 ISO to 100 ISO is 2/3 of a stop of adjustment range.

6,400 ISO to 12,800 ISO is 1 stop of adjustment range.

It's not often that all of the adjustment range is actually usable, particularly at the low light end of the range..

Though the D810 may have a range of adjustment that is 64 ISO - 12,800 ISO, DXO Mark shows the actual tested low light ISO performance is the same as the D800.
