Let this be a warning if you are anywhere around lasers. They can easily destroy the sensor on your super expensive camera. That’s what happened to a Canon 5D Mark III in this video:
The damage happens at around the 0:03 second mark, just when a laser rips through it. In fact, any CCD or CMOS sensor is at risk. Such lasers are often used at concerts or events. I’ve even seen some shops use them, so be very careful anywhere you see them.
