Hi Kayakjunkie
about your question : 4) Batteries. Fuji or generic? Has anyone seen any difference in performance, charge duration, charging time, longevity, etc.?
I use Patona batteries. You've got the yellow ones and the new green ones, which are more powerfull.
I noticed a difference in the charge indicator you can display in the EVF, which indicates the remaining power of your battery : with my Patonas, the level jumps from 2 remaining bars to nothing abruptly.
But knowing this, they are great.
