Ah, once again it's that time of year when manufacturers announce the replacements for cameras I never got a chance to review. At the top of that list is the Pentax Q10, the company's update to the Q, an odd, tiny interchangeable-lens camera based around a point-and-shoot sensor. On the upside, at about $600, the Q10 kit's a little more reasonably priced than the Q and has a slightly improved battery life (though still woefully short). In exchange, Pentax has has improved its metering sensitivity a bit and claims to have improved autofocus performance. Plus, the camera design looks like it's plumped up a bit, and forgone the white and solid black for a snazzy red and retro black and silver.
While sensor size isn't the be-all and end-all of image quality, it's kind of important in this category, especially if you don't have really good, fast lenses to compensate. The Pentax 02 kit lens offers an aperture range of f2.8 - 4.5; for an APS-C sized sensor that's great, for a 1/2.3-inch sensor it's the bare minimum to even attempt produce equivalent images. And it's why Pentax makes a big deal of the bokeh defocus control, along with the fact that the kit lens has only a 5-bladed iris so you can't optically get soft defocus effects.
Along with the Q10 the company announced the $299.95 Pentax 06 lens a 15-45mm (83-249mm) f2.8 model with extra-low dispersion elements and better-than-average coatings, which sounds a bit nicer (I don't know the aperture geometry). But most of the Q-mount lenses at this point are still toy lenses.
To compensate for the dearth of lenses, Pentax has also announced a $249.95 K-mount adapter for the Q series, which will allow you to use older lenses with manual focus only. The adapter has a built-in mechanical shutter.

My take: I still don't think it'll be worth it. If you have a collection of K-mount lenses and want to stick them on a mirrorless body, you're better off with the K-01, which has great photo quality and won't be overwhelmed by the bigger lenses. It's slow, but I'm guessing the Q10 probably won't be so fast either. If you're just looking for small, a few inches here or there don't make that much of a difference, and you can always get a Micro Four Thirds-based camera with a small (but not as small) sensor. Still, the Q10 has dashing looks that might make it attractive compared to a fixed-lens point-and-shoot. Hopefully, I'll get a chance to test this one.
