Re: Lens storage question
Congrats on your new kit. I wouldn't worry about stacking the lenses.
Re: Lens storage question
are they stacked with absolutely nothing separating them? if so i would get a piece of bubble wrap and cut a piece that can fit between the lenses (maybe double it up). i think something as simple as that would be worth it, just in case.
Re: Lens storage question
The weight will not be a problem at all, if that is what you are concerned about. But having something like a piece of bubble wrap, as herg suggested, would be a good idea. It would prevent the lenses from bouncing around against each other when you are carrying the bag.
Re: Lens storage question
I wouldn't fret. But I would wrap them in cloth just to prevent scratching the lens body.
