To save weight, I could delete 4 of them at your request and take an offer.

In fact, I will list them high and expect you to make an offer, and you must give me something like the city or state so I can figure shipping.  (  Shipping is likely going to be 30-48 dollars  unless you ask for a subset ).   The exact box size is unknown,  Most cameras weigh 1.3 pounds.

Here is the detail I can give you:
