Damn it! If you takes pictures long enough you're going to crack the glass protecting the LCD screen on your DSLR. I'm pretty careful when I travel with my 5D mark II, I use a pelican case and make sure everything is secure. This crack was caused when I closed the top and one of my gopros put too much pressure on the screen. I didn't know it until I opened the case and you can imagine my horror....
Relieved to know the camera itself was ok, I set off to fix it!
If you take your DSLR to a camera shop it can easily cost upwards of $250 to fix it plus if you live in a smaller city like I do, you have to send it off.
This fix cost about $20 and takes 5 minutes, literally.
