Understanding max iso

Max ISO is a numeric spec measured in raw units. On this metric, higher values are generally better, but returns diminish past category-typical thresholds — going from a low value to a mid value usually matters far more than going from a mid value to a high one. When comparing two products, focus on the percentage gap rather than the raw delta: a 200-unit lead means something very different at the low end of the range than at the high end. Pay attention to the unit, too — manufacturers sometimes quote peak or burst figures that are not sustained in real-world use. Cross-check the published number against independent measurements where possible, especially for performance and battery claims. Finally, remember that a single spec rarely tells the whole story; the Mars Score weighs max iso together with the rest of the spec sheet so one outlier doesn't distort the verdict.

This matchupIn this spec, EOS R6 Mark II and α1 II are effectively tied at 102400 — buyers can treat them as equivalent on max iso alone.
