Resting D7100 w/18-70 on Tamron 70-300
I recently bought a Lowepro Passport Sling II, to use as an every day bag in which I can safely store my D7100 with 18-70. On occassion I'd like to bring my Tamron 70-300 VC along as well, I've noticed this fits only when I put my 70-300 lying flat on the bottom of the camera compartment and then my body with 18-70 on top of it. There is of course a dividing cusion between the two, but the 70-300 would take all or most of the weight.
Does anyone know whether this (kind of) lens can take that kind of weight? Any input would be much appreciated.
