Smaller is better. With 19 millimeters of thickness, The Pentax Optio S6 is a barely there ultracompact, though you won't be able to tell that from the sharp photos taken by its 6 megapixel sensor. The camera's Tracking Autofocus keeps the most fidgety subjects from showing up as a blur, but we figure that most people will be too transfixed by the elegant, stylish design of the camera to wander very far. For the most recent model, check out the Pentax Optio S12.
Pentax, who just recently merged with Ricoh, has long been a sort of underdog—but not necessarily in performance or quality. Pentax/Ricoh offers some quirky cameras, but for the most part, we've found that to be a good thing.
The Pentax/Ricoh DSLR’s are mostly weather-sealed, giving them a unique advantage over competing manufacturers that don't offer anything similar. When we tried out models like the K-50, we were quite impressed with the image quality. The autofocus was a bit noisier than a Nikon, but the weather-sealing and often better price is hard to resist when the image quality is so good. Pentax continued to add in innovations by adding an anti-aliasing filter that can be turned on and off to the 2013 K-3.
Pentax hasn't jumped into the mirrorless battle too much, but they do offer the tiny and colorful Q7. With a smaller sensor and a smaller price point, the Q7 and similar models are more of a consumer mirrorless than one for the enthusiasts, but it's an extremely small camera with a whole lot of color options.
Pentax has a few solid compact models out too. The Pentax MX-1 earned our Best Budget Advanced Compact for 2013 for its advanced features yet small price tag. They offer a waterproof line that includes macro ring lights built in, something unique to the WG cameras.
Pentax/Ricoh may be a bit quirky, but many of their cameras are well worth a look and offer excellent image quality for the price.
