Re: Difficult decision...
See if you can hire or borrow a Fuji before you buy.
I had the Fuji X100 ( not the new S ) and it was a real love/hate relationship. It could be wonderful and very very annoying at the same time!
In the end I sold it and now have a NEXF3 which leaves me much calmer after shooting!
