So generally, I’ve always understood that the lowest ISO is best to shoot at. Though with newer cameras, they usually have a higher base ISO and in some cases Dual ISO.
I usually work with the R5C, even for photography. It feels odd to take portraits at 800 ISO because I’ve always been told it should be as low as possible.
So does the Base ISO system, negate the need to shoot at lowest ISO for the clearest and least grainy image?
These days, because of modern technology, (more from recent lightroom update than sensor) I don’t even worry until ISO 3200. It’s more important to have right shutter and aperture for the subject than have lower ISO… unless we are talking about ISO25600 unholy noise slush.
