I'm on a roll here and let's talk about auto ISO . Frankly no one has this right yet from my experience. Every manufacture try's to protect you the shooter as in most cases it pushes the ISO higher to save you from low shutter speeds. It's why I never use it. In this case I have no doubts it would push me to ISO 3200. No doubt in my mind here. Now some cams you can control the limits of the high and low ISO but it will still no doubt about it push you to your limit in poorer light. Which many times is not what you want. Its a nice tool but again you need to know what it will do and I see complaints about this often. Even in good light it might push you to ISO 200 or above and your trying to shoot at 100. So care needs to be taken here. All OEMs are trying to protect you here as rule of thumb for them is not everybody is a expert shooter or should be.
