|Accurate metering and precise exposure control assure you of beautiful images minus the guesswork. The EOS-1Ds Mark III employs an improved metering algorithm and a newly developed 63-zone metering sensor linked to the 19 cross-type AF points, giving you more consistent ambient and flash exposures less affected by light reflecting off the main subject. Four easily selectable metering modes combine with four shooting modes to deliver the right shooting combination for any assignment.
||For situations in which the proper exposure lies outside the selected range, the camera can automatically shift the ISO speed setting to achieve the proper exposure*.
