Can anyone advise on issues I am having with some photos that I've taken on my A71. I take the photo, the thumbnail looks OK then sometime later the photo is un-viewable. It doesn't seem to make a difference whether I save the the internal memory or an external SD card. I've tried re-setting the camera to default settings. That's not made a difference and it can happen on some photos on a particular day and not others. I've viewed the file properties via a PC and when I go to the details tab both the image properties and the camera properties have been wiped (or never recorded) from the broken images.
