Hi Peter,
congratulations for your find. I have an A6000 and I enjoy it more and more now that I am beginning to be familiar with it. Regarding lenses, I did not manage any good results with legacy glass and adapters (Zuiko, Pentax, M42 Industar...), but your experience may be different. I find the Sigma DN series (native APS-C Sony mount) to be quite good and cheap. The Sony pancake 16mm f/2.8 is very soft outside the center, not recommended. Lately, I have been using a Zeiss Touit 12mm, and it is in a diferent league, with price to match.
Attached is a picture taken with the Sigma DN 30mm.
