According to Cine4Home the Sony 1000
contrast ratio is reported:
"The native contrast ratio amounts, as with the previous series, depending on the zoom and iris settings (it can also be operated static), (on iris, zoom, max) between 8,000:1 and 18,000:1 (iris, zoom min) . "
From the above video the similar 50ES calibrated, measured contrast is 6800:1 (at 11:53 minutes) @1400 lumens.
Their 30ES measure 3200 to 5000.
The native contrast appears to have improved over the 30ES.Edited by HiFiFun - 9/29/12 at 7:37am
