I am still new to the Z5 . but i have noticed some thing that Im not sure is normal. when I compose a photo I sometimes adjust the iso or ev . When i push the button on the top of the camera to make the adjustment the rear screen activates , and it is easy to accidentally change the settings by touching the screen. Is this normal behaviour for the camera . Have you experienced this and is there a way to stop this. Thanks for any advice you can offer ? Thanks for all the past support frorm this forum .
