Question Auto ISO

There has been quite a bit of discussion in the photo press and fora regarding the "base" level ISO for the sensor in the E-620. Although not documented by Olympus, it seems generally accepted that although the lowest ISO setting is 100, the "best" base setting, ie the level at which the optimum definition is available, is ISO200.

Now, I've been playing with the Auto ISO setting on my E-620, and have discovered that, whilst you can set the maximum ISO setting to anything you want, the base ISO setting is 200, and not the 100 which is the absolute minimum.

This seems to reinforce the opinion that ISO100 is an artificial low setting, and the true base level of the sensor is indeed 200.

Or have I missed something?
