I was using my Q7 today with the LCD magnifier in bright sunlight, It works well when using a baseball cap. I must have held the camera at just the right angle to let the sun focus through the magnifier on to the LCD with the camera switched on and burned out the LCD right in the center. See images
See yellow lines and spots in center of the LCD when camera is turned on with lens cap in place
Also shows up when using the camera focusing on subject
This image with camera off you can see the damage,
So everyone be mindful when using this type of device and keep it shaded. I have used it many times on both my Q and Q7 and never had a problem. I assume the same thing can happen when using a hood with a magnifying lens that I have also used many times without problems.
The camera still works fine and no problems with the images but it just pi**es me off every time I look at the LCD
