I have a Sony a6400 camera and I have done several tests with the "Sony DSLR" driver, in general it works acceptable but there is one detail that I don't know if there is any configuration that can help me. The problem is that it does not use the Delay to wait after taking the photo, it only waits approximately 20 seconds and checks how things are and if it is not there, try to take the photo again, if the time is less than those 20 seconds It works acceptably, at 20 it fails completely and after 20 it makes 2 attempts to photograph. I would appreciate your support if there is something that can be done, thank you very much in advance.

I already found the solution, sony cameras usually have a noise removal process activated in long exposure photographs, which will cause that process to take practically the same time. That does not mean that it does not take into account the delay that is configured, but it allows me to take photos with more agility.
