I actually like mine.I've orderred a black 17/2.8 for the white E-P5 that lives in my belt pouch. Together, they should look stunning.
I know that this lens gets bashed a lot as not sharp enough, but the many reviewers on Amazon and B&H Photo disagree. Photodo rated its resolving power as almost as good as the 17/1.8. Mostly I'll use it between f/4 and f/8, its sweet band.
Abive all, I'm smitten by the subdued rendering and natural colors I've seen in this showcase.
To my pleasant surprise, the 17mm f/2.8 lens can accept the Olympus LC-37C automatic lens cap; there's a short video showing this combination in operation on YouTube. I can't help but wonder whether more people would choose this lens if they knew.
