So I've been playing with Image Transmitter 2 (V2.0.0 (18)) and all in all seems good.
It installs pretty painlessly, and you're up in running in a few minutes.
The camera needs to have in the menu, your USB connection set to PTP.
Starting at the top, set your destination folder. Below that is camera connection, then battery level, shooting mode, AF, shooting parameter profile and then SD slots and file types; all of those are only controlled through the camera and there is no option for the software to adjust them.
Then comes exposure settings, shutter speed, aperture, ISO and EV; these are adjustable on both the camera and the software.
Next there is a little green dot button, it acts as your instant meter reading and sets the exposure accordingly.
Then there are three buttons below that, for LiveView (LV), Auto Focus (AF), and shutter release.
Next there is a check box for "AF when released", forcing the camera to do an auto focus before the shutter is released.
Below that are your option to save to card 1/2 and the file types you wish to save.
I worked it over quite a bit this afternoon and managed to not get the camera to be recognised a few times. This was always cleared up by turning off/on the software and camera, easy.
I have it set up so that Lightroom is watching the folder and auto importing the files into the open catalog. Transfer using a 3 foot USB3 cable is about 7 seconds for DNG only.
I'll be doing a more in depth test maybe tomorrow in the studio.
