So I did more research and maybe I can just continue to use the EPL1 and buy something like a Panasonic 20mm 1.7 lens. I more into street photography and bokehs so would that lens be good? If yes, know of a place where I could buy one and how much?
I have the impression that the EPL1 has pretty slow AF (from what I can really handling it about 2yrs ago; and I consider myself having not too high a standard wrt AF speed).
But since its 'free', its fine
If you want shallow DOF shots, look at the 45/1.8.
The 20/1.7 is more versatile though imo, and its my lens of choice most of the time.
Whether DOF is shallow enough for your requirement, I think you need to see more samples online.
Look at how the lens renders the bkgnd for head/shoulders shots, half body shots, full body shots, to have a rough idea of what it can do.
Other factors like bkgnd distance plays a part too, but often enough the samples will give you a rough idea.
Note that if you stick w/ m4/3, your working distance will be different from that of aps-c or ff.
IMO, 45mm or 75mm is about as long as I'd get a good working distance with.
Any longer and there is a need to stand pretty far from the subject to get a half body shot or full body shot.
Not impossible with a longer lens, just need to stand further away ( with its associated issues)
