Keep the Oly 17mm 1.8 or the Panasonic 20mm 1.7?

I know the feeling. If you got the excellent 45mm for say $328 via Korea like I did, them you might wonder if you got screwed paying $499 when the sharp as tacks P25mm is only $49 more.

Well, there's enough margin in this lens that after the early adopters buy it, its street price may drop to a point where people like you and I feel good about owning one. Return it, and I'll buy it as a refurb for $379.
