Hi Forum Readers,
I am trying to understand the practical advantages of using the extra micro delay functionality on a H6D. The options are None, 25ms, 50ms, 100ms and 200ms.
Can anyone advise on the practical uses of this feature? There is also an option not to return the mirror in conjunction with the above.

I gave you the technical aspects of the function earlier, here's a practical application of it. If you're doing a landscape capture, you've finalized composition, optimized focus and locked up the mirror. The camera is also steadied and weighted down on a tripod; nonetheless, the wind from time-to-time picks up and the force moves the assembly slightly and all resettles in a matter of seconds. Setting the delay (milliseconds) allow you to continued capturing, as it compensates for the difference in time between the winds force (vibration) and the resettling. Therefore, you would set the delay duration based your judgement of how often or how hard the wind is blowing. You can also do a focus check by zooming into the image on the display, to see if the setting compensated for the vibration/movement and if not, increase it by a factor.
A second application would be if your during rapid captures or sequences. If the mirror is not locked up, every time it flips up it creates some level of vibration (movement) that adversely effects focus. So you can set a comparable delay, to compensate for the vibration generated when it flaps up between each capture, this assuring you that all has settled before capture and focus can be optimized.
