)
I have just taken a couple of snapshots for you, so excuse the quality. Hopefully they will give you some sort of idea.
I'm not sure what a normal lens is, but I guess you mean not massive ones. If so then 3 bodies and 10 relatively small ones would be okay.

Standing next to a 1550 Peli case.
Note that the Peli cases are heavy before you even put anything in them BUT once in they are well protected

& Peli's have lifetime guarantees.
