Turn your camera off before doing anything to it is a wise move!
Before doing anything to your camera, always keep in mind that you should turn it off first. No matter what it is—swapping lenses, changing memory cards or disconnecting or attaching cables; switching your camera off should be an instinct.
Keeping your camera on when it is writing to the memory card increases the chance that you’ll ruin the card if you abruptly remove it. Similarly, if you change your lens with the camera still turned on, you increase the chance that dust winds up on the sensor.
Turning your camera off also helps with battery conservation, this can potentially spare you the cost of the extra battery.
Getting in the habit of turning off your camera before you either add or remove something is no trouble at all, so remember to do it.
Major brand names are major people pleasers
Here’s a nightmare scenario that any camera owner will absolutely hate to happen to him. You’ve just bought a new digital camera, and you’re using a new branded lithium battery. However, due to reasons unknown, the battery all of a sudden starts to leak, causing damage to your camera and camera equipment.
A major brand like Canon will go the extra mile for its customers.
Should you throw the battery away in this case and just buy another brand’s battery hoping that it won’t do the same, destructive thing? No! Instead, get in touch with the brand that manufactured your battery. Tell them about their battery’s problem and send them the damaged battery along with the repair invoice for your camera and equipment. Most major brands have a corporate reputation to protect; as such, they’re willing to pay for your damage once you send them the repair invoice. Simply call up the manufacturer or their representative and request instructions on how to go about this process.
