Originally posted by Ian Stuart Forsyth Most modern cameras can survive a great deal of abuse, while all it takes is a single small impact that can cause damage to the camera, this damage may not even show up in day to day usage for sometime until it does.
One of my K5 I had broke the strap lug I found I damaged in the camera bag that was stored in a hard box
Our K-5 is now 12 years old and has been hauled all over Algonquin Park, carried on miles of portages, sometimes as much as 50 miles on one trip in Pelican cases and waterproof bags. It's still in perfect functional condition )maybe little aesthetically scarred) despite almost 100,000 clicks. My K-3 has been dropped enough to damage the lenses on it 3 times, one of those sling shotted into the ground by it's strap breaking my DA 55-300 in half, and yet still functions perfectly after 160,000 clicks. So you can also have a lot of really hard knocks, with no damage at all. Based on my experience, that's a lot more common than what you describe.
