Here, we see a model of the Canon EOS 5D Mark III camera. The model on top had a bit of an LCD light leaking problem. In very dark environments, the LCD display panel on the back of the camera was so bright that it actually would cause the auto-exposure to refocus the camera based on the new amount of light that was available. The solution? Why, a piece of black tape over the LCD display panel, of course! Not even fancy schmancy cameras are above the power of kludging!
