In reply to Andrew W:
I had a Sony A6000 for a while. It was OK, but just didn't like the 'Sony' look of the images and the RAWs just couldn't cope with much editing. (bought and sold it 2nd hand, lost nothing)
Now a Fuji owner and love it.
I'd recommend looking at Oly-Fuji and see what you can get new or 2nd hand for £500.
e.g you should easily pick up a 2nd hand X-T10 & kit lens for less than that or even an X-T1.
