I've read several times now that some of you work with ISO 1250. What's up with that? I either have 800 or 1600 to choose from. Can somebody please fill my knowledge gap - I'm sure I'm missing something important here, thanks.
Set your camera to Manual 'still' mode. Mode "M". Press menu, select the top icon on the left side (its looks like a still camera body). Page down to page four on the right hand side of the options. Change the "ISO INCREMENTS" from "1 EV" to "1/3 EV".
Done.
