Luke's brief interest in the Pentax K-01 got me thinking about that camera - an interesting experiment and valiant but misguided effort to produce a stylish, mirrorless camera that preserved the K-mount. Alas, the K-01 seems to have generally failed in the marketplace - at least at its original price point. But people scooped it up with the DA 40mm XS lens on closeout. Size didn't help the fate of The Brick, methinks. Nor did the styling, lack of a viewfinder and so-so auto-focus speed. But the K-01 did, in fact, have (and continues to have) a quirky appeal and delivers excellent image quality on par with a K-5 and K-30. And, frankly, the K-01 is fun. Just like the Q. I hope, outside of the Q, that Pentax hasn't given up on mirrorless, interchangeable-lens cameras. Actually, after seeing what some other companies have done in the mirrorless APS-C space (Sony NEX, Fuji XE-1, X-M1 and X-A1), I think Pentax could rework the K-01 concept into something more compact and every bit as appealing as the competition - even while retaining the K-mount. Fuji's X-mount lenses - and Sony's E-mount glass, for that matter - are not what I'd consider tiny. So I don't think the K-mount is a problem: Consider the DA Limited primes. Or the new DA 20-40mm Limited zoom. Even the hoary, old DA 18-55mm and 55-200mm kit zooms. All are small and light enough for such a camera - and give good results. And the best part is, they're already in stock. I'd love to see Pentax's unique take on the Fuji formula. It's something they could easily do with a lot of existing technology that they already have on the shelf. What's more, contrast-detection auto-focus has come quite a way since the K-01 first appeared. I think this concept for Pentax would work in the marketplace, now that the company has had a chance to see what others have done and what people are buying. But I'd want a viewfinder - either built-in or as an add-on option. Any thoughts? Do only Pentaxians who already own Pentax glass want such a camera? Would you be seriously interested in one? How much would you pay for it? Or am I deluding myself?
