Right a rather simple question here, ive searched a bit and cannot find an answer to it!

Why does the D700/D3 use iso 200 as default and not iso 100? I know the noise at iso200 is going to be more than minimal but wouldnt it make sense to use iso 100 more often if you have the shutter speed/aperture available?

Maybe a bit of a silly question but i am curious.. Hopefully someone can answer!

Thanks.
 
I think being honest there would be no difference between the two quality wise, the IQ at 200 is excelent, I argree lower ISO's would be usefull, but more for the ability to set very long shutter speeds that to get any quality improvement.

It's a Nikon feature and isn't consigned just to their Full-Frame camera's. You can always set it to Lo1.0 which gives you ISO100 if you really want to.

Ah, i know this but what i do want to know is why you have to select Lo1.0 and its not just set at iso100 in the first place.

Like i say its just a silly question and the difference is going to be minimal. I can understand it possibly making a difference on incredibly long exposures though.
 
It's to do with the ISO organisation. The native setting for those sensors are 200, so that's what they get set to.

The Lo1 is still good quality. I've used the D3x at Lo1 (iso 50) just recently and can't see the difference in IQ.
 
Plus, the D3 is aimed more at news, sports and action photographers, so it's more useful to be able to use faster shutter speeds and higher iso settings...

The D3x starts at 100 and goes down to Lo 1.0 - an effective iso of 50...and isn't as effective at higher iso settings, which don't have the range of the D3...

Arkday, I see you have both D3 and the D3x.

Is there more than 1 stop difference in "useable" ISO between the two?

Yes - at the top-end - on the D3x I'd not go above 400 (since I have the D3, otherwise I'd have to if the situation called for it)...

The D3 allows me to go up to riduculously high ISO settings with very little loss of image quality...so far, I've used up to iso3200, though it will go higher...

One's definition of 'useable' also depends on the application...for action-shots, anything is useable as long as you get the shot - for portraits or fine art-nudes, minimal noise is preferable (to me).

Thanks for that (and apologies to sparkoss for hijacking the thread).

"Noise is in the eye of the beholder" - I agree

I can't afford either camera, but it was something of interest to me.
