I’d go for Fuji if you liked the feel of the camera, but personally I use micro 4/3 for wildlife - an Olympus OMD-EM5 Mark 2. Slip a 17mm prime lens on it and it’s pocketable too. I use an adapter to fit a fuck off 400mm manual focus lens on it though, which I original bought for use with my Minolta gear - the resulting 800mm reach really brings stuff close.
