Previously A77 user then went to Nex 5R for light and smaller package.
Recently sold all my Alpha gear and dive into the XE2, what I can say is WOW and I do regret not getting it EARLIER!!!
Had been holding on to the change as XPRO1 was damn expensive and XE1 had medicore AF speed. Since XE2 has the improved AF and new sensor, the decision for me was easy.
In terms of image quality, I would say Fuji is the best in APSC sensors. Impressive colours and noiseless even up to ISO3200, and this is the first cam i owned that i do not hesitate to use ISO6400 frequently.
I managed to shoot my son's concert 2 weeks ago with very low lighting. I only used the kit lens and ISO6400 and managed to keep my shutter speed at 1/125s to capture all the movements and dancing on stage. I have never been able to do that with my previous gears without flash.
Even with the built in flash, i am able to get really nice fill flash while maintaining the background still nicely exposed. Somehow Fuji is very good in balancing the both, even shooting with flash, ISO still maintains quite high at ISO3200 or so and yet still its noiseless.
I am sold to XE2, its the best cam ever for me. Unless you have the $ to go for A7, this is the best cam money can buy.
One more thing, the kit lens 18-55 f2.8-4 is fantastic. Its very sharp wide open and corner sharpness is good, in terms of kit lens, it is the best and its 1 stop faster than most. Coupled with the fantastic high ISO of XE2, this combination is the low light beast.
