We had a little get together for my boss who is leaving our branch to take another position within the site (different building). I had my camera with me to capture these last moments. It was mentioned that another coworker is also big into photography. I had my Sigma 18-35 on my K-5 IIs with grip and he said, "Yeah, but my camera isn't nearly as fancy as yours. I've just got a Nikon, one step above the entry model." That seems like a victory for Pentax.
Although I think the win needs to be shared with Sigma. That lens is a beast that draws attention. It makes me think that the only reason Canonities get so much attention is that all Canon lenses are constructed from hollowed-out bricks. It's seemingly the lens that gets the oohs and ahs, not the brand or camera body.
