In the viewfinder, you can see the split-image in the center and LED at the bottom right.
That LED turns on when you half-press the shutter button. When it is green, the shutter speed is fast enoght to photograph. But if it is yellow, you may as well prepare tripod or something, for the shutter speed is too slow.
In addition, the LED doesn't turn on in case the batterys run out.

Finally, we are set to shoot.
We suggest you to press the shutter button gently when taking pictures, for the camera is small and light.
