most of us have no real use for the weather sealing but, like so many things, many feel that once it is there , not having it is like missing out on something, even if they will most probably never use it.
Perhaps it perceived as a sort of emasculation to not have the best , the top, of anything. I’ve often been rebutted that “ i do it because I can afford it” .
I personally wouldn’t make it, unless you are sure to use it, the criterium to buy a camera. WR costs a lot of money as opposed to a camera without that.
Unfortunately robbery has become all to commonplace on the Inca Trail. Expensive cameras are calling cards for opportunists. Whatever you can leave at home, leave at home. Buy yourself an unobtrusive X70 and embrace its limitations. Spend time creating memories with your new bride. My $0.02. YMMV
