Dualiso frequently, but not always, fails to trigger when using LiveView on 7d
Created originally on Bitbucket by cwm9 (c m)
On the 7d, if dualiso is turned on and a shot is taken while in live view, the shot is not generally taken with dualiso, even though a shot is taken.
If LiveView is turned off, dualiso works as expected.
Sometimes it works properly for many shots in a row, then will suddenly stop working. I have tried but failed to find anything that correlates with the failure.
