Why is the camera turned black after the camera is turned on?
After the camera turns on the lens, the display is black and has the following situations:
The old SLR camera does not have a reflector function, that is, you can not use the display to take the mirror, so when shooting only with eyepiece, the display is only used to view the photos.
Lens failure will cause the display does not show the front three cases are excluded, that is, the lens failure, and need to send after-sales testing.
The new SLR basically have a screen to take the mirror function, but to manually open the brand SLR switch settings need to refer to the instructions.
Lens cover forget to take, but also made the boot after the display is black.
