I'm currently considering an upgrade from my 645Z to a Phase One XF 100 MP. It's really great to have a camera that allows to set the shutter speeds for long exposures in camera instead of fiddling around with an external remote. However, from a demo video I've seen it seems that even for long exposures there are only shutter speeds available for every 1/3rd stop or 1/2 stops depending on the user settings. This is totally fine at exposure times shorter than a couple of seconds. But for long exposures when capturing events that take a distinct amount of time I'd prefer to be able to set the shutter speed down to the exact number of seconds.
Is there any way to set the long exposure shutter speeds more precisely with the XF?
