I thought ISO was where the military got free coffee and donuts, and enjoyed flirting with the pretty volunteers.

It's back to the books for me...

At ISO 200 noise is almost non-existent for all of the latest Canon or Nikon DSLRs. Using a non-native ISO 100 (Lo-1) in order to shoot at f/1.4 in bright sunshine causes negligible IQ degradation.

Having an auto FP high speed sync speed of up to 1/320s also helps for shooting wide open with flash.

I guess that I had it backwards -- this means that the camera film/speed/sensor gain setting must be USO. ;)

When I was in the Army and got my first SLR, film speed was ASA. There was also a European standard known as DIN. It took a while for me to shift gears to using the abbreviation for the international standard, but at least the numbers were the same as ASA. I think that the fastest film speed for color was ASA 64.

I never did see the pretty girls. :(

I always thought that Nikon just has better ISO performance in their cameras, but they lack video and color accuracy mostly. Maybe that is why they start at ISO 200 for their high end bodies. I think they are used a lot by people who shoot indoors for weddings and portraits and need to have that great ISO performance with low or no noise to get those faster shutters and better AF in low light low contrast situations. Maybe I am totally off here.

I have used a D3x for >2 years and it starts with ISO 100. All other today Nikons start with ISO 200 which made them hard to use in studios or with fast primes wide open. I am not really a friend of that high ISO and feel much more comfortable with my 5DMKII which I use now.

Cheers,
Martin

This is what I heard about ISO for 5D2. :rolleyes:

Best ISO performance - ISO 160 320 400 640 800 1250
Worst ISO performance - ISO 125、500、1000 -
ISO 125 is worse than ISO 640

It is because 200 is the native ISO for the chip. Moving to 100 would be actually make a grainer image as there would have to be modification to the signal. The same as if you raised the ISO. Evidently they decided a better picture was worth more than not having to use a ND filter.

Nikon colors are just different out of the box to Canon. You could argue that neither system produces colors that are "accurate", just different. :D

Folks saying it doesn't matter probably don't shoot with studio strobes in ambient environment. NF filters is fine but can be pain if you need to stick 6 stops or so. I anomaly use 3 stop filter and use ISO 100 or 50 on my 5d. If I had to use ISO200 I will hate it.

Agree that the 5D MKII bests the D700 with regards to having a non-native ISO 50 versus the D700 non-native ISO 100. The D700's faster sync speed of 1/250s isn't a big help, while it's auto FP high speed sync of 1/320s is great as long as the reduced capacity due to HSS isn't an issue.

For shooting wide open with strobes in bright sunlight the D3X (native ISO 100 with non-native ISO 50 and a max sync of 1/250s) is a better, but much more expensive alternative to the D700.

And perhaps their 200 is the same as Canon's 100? I've owned the D3. ISO 200 on it is as clean and sharp as any Canon at ISO 100.

Honestly I can't see any difference coming out of any APS-C, APS-H, or FF body made in the last couple of years at 400 or lower. As has been posted here several times if 200 is a problem get a quality ND filter.

I honestly do not understand why people worry about this.
i understand the studio shooters grinding their teeth at having to use ISO 200
but if you do stop down, would you see a difference on PRINT in terms of IQ degrading? probably not.
Fine, use a ND filter, which MAY cause IQ degradation... but would you see it on the print? Probably not.
Even if you print it on a... say 80x120, you'll see the degradation if you see it in your face/pixelpeep, but if you print it on a paper that big, you should be seeing the image far away...

the point is, we can't tell a single difference whether we use native ISO 100 or not...
our eyes aren't that sharp like an eagle's eye. I'd rather worry more about the composition.
