I installed Helicon Remote on my android phone to give it a try. One of the features that I am more interested in, is the automated focus stacking. It does work, and I enjoyed the first couple of days with it. But for some reason I can´t set my shutter speed bellow 1/30s. I wrote to Helicon on their Youtube channel and they responded that it is some specific in-camera setting that I have, but they couldn´t help me with which. They did suggest that I saved all my settings to an SD card and reset my camera to default, but I was hoping that someone here knew which specific setting is preventing longer exposure by the software.

Query:  Just for clarification, when you say "below 1/30s", do you mean 1/20 or 1/50?  I hate reciprocals.

I´m sorry for that! I realize now that was confusing. I mean I can´t set a SLOWER shutter speed/longer exposure
