I've adopted two 16mpx Fuji bodies as my casual events fun camera system. Without a doubt I'll be adding an X-T2 down the road.
Just last weekend I went to the Seattle Woodland park zoo. I used my Canon 5dmk2 with 16-35 f/4IS and 70-200 and Fuji X-T10 with 18-55 kit, 16mm f/1.4. This combo was absolutely versatile and incredible.
I burned through 1 Fuji OE battery and 3 3rd party batteries. #4 battery still had acceptable charge left at the end of the day when I left the zoo.
Just cant get over how many times I needed to swap out batteries. My Canon I had the same battery in all day.
Are most folks buying OE batteries? I've been using upstart batteries and they seem to be working acceptably well for an inexpensive 3rd party.
