D610 ISO 50 Full SNR curve and DR
« on: November 04, 2013, 05:21:44 pm »
This a comment for this page on the website
I noticed that you measured a Full SNR curve at ISO50 for the D610, which would result in a DR of 14.0 stops at native resolution, equivalent to a heretofore unseen 14.8 'Print' stops of DR.

Any reason why this reading remained unmentioned and was not included in the charts?  It's rather jaw-dropping.

Hello,

Thanks for your comment.

In fact the ISO 50 measurement was not the right one and it is not taken into account for score computing because of its real sensitivity: ISO 50 is not a real ISO as measurement show that the sensor provides the same sensitivity at ISO 100.
We updated the measurement for ISO 50 which is exactly the same than ISO 100.
