[QUOTE="WayneF, post: 536631, member: 12496"] Thanks very much John. The D7000 is one I was very much interested in (near group division lines), and your data obviously shows (now) group C is correct, so it shows my assumption about it was wrong. The D800 is the one that caused so much commotion about this change (for the better), so I assumed it was first, but your data shows the D7000 (18 months earlier) had it first. I'm surprised it did not cause attention then? Your screen shot suggests your subject distance was fairly close, maybe 3 or 4 feet? That could cause different results. Could I please ask that you repeat this, same thing, but at more like 10 feet, just to be certain? I would very much appreciate knowing for sure for the D7000. The 1/100 second is your Auto ISO menu setting of Minimum Shutter Speed. It is the threshold where (in falling light), falling shutter speed stops and holds there, and instead, Auto ISO starts increasing. Your Auto ISO without flash was 1/60, which implies that 1/100 second was not sufficient even at ISO 6400 (without flash), so shutter speed had to continue its fall then. In that way, the 1/100 is not an absolute limit, but it is the shutter speed that will be used with Auto ISO, that is, when between minimum and maximum ISO. But if "AT" minimum or maximum ISO, those are limits, and shutter speed may have other values. [/QUOTE]
