I've posted this before, but...
Allow me to submit this as evidence for the toughness of the K-7. Watch all the way to the end. Three months, and many frames later, body and lens both work just fine. That same body has also spent plenty of time in the Joshua Tree desert, been in many rain storms, been clamped to the outside of a VW bus for 45 minutes of driving in a thunderstorm, been left on the roof of my car in a lowepro toploader which then flew off the roof as I drove away, and has been generally abused it's entire life. Besides being fairly scratched, it is still in perfect working order.
