Do you store the camera body and lens apart when not in use?

what makes you think that nikon is too fragile?

That was my guess... or maybe a bad joke... sorry Nikon...

Seriously, I never heard of lens mount tear and wear before. Maybe our fellow pro photographers, who often change lenses dozens of time per day every day, can share their experience.

If you have more lenses, can also consider more bodies ;p .

For bags, consider Tamrac also.
