- An attempt to change Av usually (but not always) locks up both cams (neither has adjustable iris), probably depends on lighting conditions
On my non-adjustable iris cameras, and the original script,  adjusting Av would engage the ND filter (or disengage).  The actual code 'scrolls' though the Av range looking for a "lock". That might have to be changed.
Applied philmoz's patch and tested on A1200.  Adjusting Av now hangs the camera as srsa_4c reported.

Original script on patched build still works when adjusting Av ( ND filter goes in and out).

All my cameras have a real aperture so I can't test this - anything in the ROMLOG of interest?

What happens if you leave the calls to FA.Create and InitialiseAdjustmentSystem in the 3.5 script version?
I'm wondering if it is setting some status that causes some errors to be ignored (I think FA means Factory Adjust).

It might be better to replace the Av control with an ND control for cameras without an iris.

The equivalent-looking part of the ixus30 firmware suggests a failed check on "!fMoving".

The current script results is abrupt jumps in exposure when making adjustments.

I wonder if it would be possible to adjust the values gradually over time, in smaller increments, until the target value is reached.

This should be possible for Tv, may be possible for Sv; but probably not for Av.

Just throwing out an idea in case anyone has some time to tinker with it.

My test on SX130IS.Trunk-3347 patched with philmoz's videxp.patch and videxp3.5.lua script.Adjusting Av not hangs the camera, adjusting Tv and Sv also not hangs the camera.I do not reached the reasonable up/down limits in daylight conditions.Great job!
