I've got to admit... I'm one of those who got the K-01 at the low, low price and then took a while to figure out what it was all about. Here's one comment from that blog page that struck me:
Quote: I never really understood the purpose of this camera, since it is functionally nothing more than an emasculated DSLR.
That's it. If you look at the K-01 as a stripped-down DSLR, it's not good. If you think of it as a K-30 minus the viewfinder, minus the weather sealing, minus the second command dial... and a bit smaller, but still not really a compact camera... then it doesn't make sense. I'm sure that's why it didn't make sense to a lot of people, if they thought it was a DSLR substitute. When the OM-D E-M5 came out, you could tell at a glance that its intended role was a miniaturized SLR, complete with 1970s retro styling and fake pentaprism hump. When the K-01 came out, it looked like something from Dr. Seuss. (Although, I still think the black K-01 looks bauhaus, like the camera counterpart of a Lamy 2000.)
Then you come at it from another direction, and consider the K-01 as an overgrown Q. It's like a Q with a much bigger sensor, hand-filling grip, bigger display, bigger battery, more powerful flash, more processing power, buttons you can hit with your finger instead of the teeny tip of your fingernail, and access to the whole panoply of K-mount lenses! Think of the K-01 as a sort of digital Lomography camera: something you can pick up and play with, experiment, horse around with your camera. Try the interval shooting! The HDR mode! Try the cross-processing setting with random exposure and color errors! Try stacking the art filters and see what weird results come out! Try putting on that cheap-and-crummy old 19mm Vivitar lens that you picked up at the flea market for nearly nothing!
I think the price was the biggest sticking point. It's not that the K-01 isn't worth the money. It's very solidly built and has a great sensor, etc. It's just that "fun camera" and a high price tag just don't correlate in most people's minds, at least here in the USA. We see a camera that's expensive-ish, and we suddenly become very serious-minded and want to compare long lists of features and specifications with every other camera in that price range. Then the K-01 didn't fare well, until the clearance deals came along. And the funny thing is... If you already had a bunch of K-mount lenses, or could pick up some old ones off fleaBay, you could have come out cheaper with the K-01 (even at the pre-clearance prices) than with a new Q and a set of all-new lenses to go with it.
