When using the VersaTrigger in camera trigger mode to shoot fast dynamic images it is important that the shutter lag (delay) is optimised to be as short as possible. Looking at some web sites it would appear that each make/model of camera has a definitive shutter lag, some of which are ridiculously short.
Here in the real world we know that some of these figures are not quite true and that shutter lag does not just vary between makes and models of camera but may also vary between models of the same camera.
Nowadays, most (if not all) DSLRs are processor controlled. This processor control provides many useful electronic functions, most are manually selectable but some are automatic dependant upon other settings and it may not be apparent that they are in use. The problem is that some of these functions impact on shutter lag, each one may add just a few milliseconds to the lag but very soon a few milliseconds becomes tens of milliseconds.
So, let’s assume that for a VersaTrigger shoot; we are using a camera mounted tripod, we know the lighting (xenon/LED/tungsten) and there probaby is not a person/cat/dog in the image.
We can switch off:
We can also try a half-
