I just picked up an X-E1 used for $275 locally. It was meant to be a 2nd body to my X-T1, but then as I was finalizing the meeting plan with the seller via email, I found out my T1 had light leak so now it's going back to Amazon. I'm seriously considering "downgrading" to X-E2, or even just getting another X-E1 rather than getting replacement T1. X-E body, IMHO, has the best balance of size, usability (for someone likes physical control) and weight after handling E, T, and Pro bodies over time.
56mm, which I just received, is fantastic. Super sharp even wide open. That lens really made me decide to get a second body to basically have that lens glued to it for location shootings.
I don't know if I can really narrow it down to just two lenses, but I think I'll be very happy with 56, 35 and 23. 56mm always on one body, and another one choosing wither 23 or 35 depending on the assignment. If you are a 35mm equivalent guy to begin with, I can totally see just sticking with 23 and 56mm. That's very likely what I'll take for my regular work shoots. Since I'm a 50mm fov guy personally, I'll probably keep 35mm for my personal shoots.
