I guess that I'm pretty rough on my lenses. Being a hiking and a climber, it seems like every once in a while I drop one of my lenses.
Last night when inside my home I dropped a Nikkor 35mm f/1.8 G lens. It fell about 4 feet onto a hard wooden floor.
I cringed and thought, oh no, I just damaged that new lens!
Immediately I tested it out on my D7100. No damage at all.
I've got mostly older manual focus Nikkors. We all know how tough they are. This was my first experience with dropping one of my three newer "G" lenses. I was surprised to find that it would appear that these modern Nikkors seem to be as rugged as are the older Nikkors.
Have you also found that the newer Nikkors are tough and rugged?
P.S. I have not had such good luck with other lenses. A few years back I dropped an expensive Sigma tele zoom about 2 feet onto a carpeted floor. That little drop totally destroyed the lens.
