Word of Caution About Handling Nikkor G Lens

I know our Nikon D90 is not exactly light and fluffy, not to mention it with an attached lens.

But I kinda realized that all Nikkor G Lens are built with plastic mount (true with our 18-105mm kit lens), not metal ones! So what, you might say.

Err...this will and should change the way we hold our camera with immediate effect. I am sure we are, at times, quite comfortable holding our camera on the lens barrel section. Now, the weight exertion of the body on that plastic lens mount may well be the cause of the infamous F-- error? Could this be it?

Its a logical deduction as I do occasionally hold it in the above manner due to the longer barrel length of the kit lens.

Your guess is as good as mine...
