Images flashing black on LCD

I have a AF-S micro Nikkor 40mm lens and when i take a shot with it and view the shot on the lcd i get black flashes, i also have a D3000 so i tried the lens on that and its fine, i then changed the 40mm to a 18-55mm lens and attached it to my D5100 and that is also fine.

Heres a video of the problem

you have the Highlight Alert feature on.

Thanks Don,

That has worked, i got a touch worried, i thought something was damaged.

As soon as I saw the video I could tell that the white area was very overexposed. That is why it was flashing. Not really a bad feature to leave turned on. That gives you the option to reshoot and get the levels down now. Better than not getting the shot and not knowing it till you get home.

I agree Don,

I have now turned it back on, as you have stated its telling me its over exposed so i can then reshoot the subject.
I was a bit worried something was at fault.

I remember the first time I saw it I was freaked out too. I knew something was terribly wrong. I think though when it is active that you can click the down arrow on the multi select and toggle it off and on without having to go through the menu.

Yup. When viewing the shots on the lcd you can use up and down arrow to scroll through the views (histogram, highlights, overview and picture if I remember correctly).

Thanks very much for the tips.

​Much appreciated

It made me go back and check the menu options on my D5100 and because of that I changed the way I had mine set up. Trying to solve problems for others always helps me learn things. So Win/Win
