Cameras do not bounce

I forgot to mention a discovery I made while observing the sandhill cranes: Sony cameras do not bounce. And, even more startling, they still work after not bouncing on the sidewalk!! Yes, while futzing around getting my hood up to block the chill wind, I caught the strap of my camera sending it tumbling to the sidewalk. Heart in mouth I picked it up, not daring to breathe and certainly not expecting it to still work but, lo! it did! A big WHEW!!
