When you go to a custom's office, one needs to take all items of personalty with them,correct. I know you do for rifles,of course, but does the same apply for cameras,jewelry,optics and the like?
As was mentioned by Muledeer above. Over several hunting trips abroad I have never been asked for verification of ownership on anything other than my firearms.
If you are going to customs to fill out your #4457 for your firearms there is no harm in listing other expensive items such as scopes binoculars etc.
It costs nothing but a little extra time, and if it provides you with peace of mind there's no harm in it.
