Our friends in China need to get busy making aftermarket battery holder grips for the entire Fuji line. Don't even care about the extra controls! Ok, a release would be nice. How about $30 for a battery holder/grip for the lowest Nikons or Canon Rebels....yes, they exist.
I shot the PA Ren Faire Saturday and I had to swap batteries 3 times in my X-E2... lost a shot or two because the battery level indictor sucks. I've been shooting my Nikons since then just to get over it....
The worst part is there is almost no warning - one notch down from "full" - a few shots later, dead. It's like Nikon DSLRs were 10 years ago. Batteries are important to serious shooters, Fuji! Get it together!
(To be fair, I should point out that the heavy usage was on me a bit as I had "high-performance" mode engaged, 5 min auto off, I was using some fill-flash, some video, and it was super hot that day. Sort of a worst-case scenario. I got about 100 shots per battery. OUCH.)
