I apologize if the following information is are ready well known and posted elsewhere in this form. However a month ago I remember reading someone posting this question and there was no response so wanted to contribute. I own a gx7 and have been able to determine the shutter actuation as well as other data by using the following steps that is cut and pasted from a dpreview forum. According to that thread the steps are identical for the GX one. I have also attached photos of the data that is displayed on the GX7 so that you can see what to expect when you follow the steps below With your camera's battery well charged, perform the following steps in sequence: Insert a memory card into the card slot; Turn the camera ON and take a picture; Turn the camera OFF; Select single shot mode; Press and hold simultaneously the DISPLAY, AF/AE LOCK, and RIGHT ARROW buttons, while turning the camera ON; Now, press and hold the AF/AE LOCK button together with the MENU/SET and LEFT ARROW buttons; Repeat the last step, that is press and hold the AF/AE LOCK button while pressing the MENU/SET and LEFT ARROW buttons. A two-page operation history display will appear; Press DISPLAY to toggle between the two information menus; Write down the number next to PWRCNT. This is how many times the camera has been powered up; Write down the number next to SHTCNT. This is the shutter activation count; Write down the number next to STBCNT. This is the number of times the flash has fired; Switch the camera off to revert back to normal operating mode. Congratulations, you have successfully retrieved the shutter actuations information!
