One of the shortcomings of the very good K-5, and indeed all of Pentax's DSLRs, is the adequate if not outstanding autofocus system. The K-5 II (as well as the new "s" version) just might offer a real remedy in the new SAFOX X autofocus sensor. The K-5 II's autofocus is rated down to -3 EV, approaching moonlight levels, and should track moving subjects better than prior iterations. The LCD screen has also been upgraded to have no air gap, which should improve outdoor visibility. These changes are, however the only truly compelling upgrades. This isn't necessarily a bad thing - the 16.3 megapixel sensor, weathersealing, 100% viewfinder and Shake Reduction (SR) are all fantastic - but such incremental changes aren't likely to excite would-be upgraders. Pentax will also be releasing an "s" version of the camera for a $100 premium that lacks an anti-aliasing filter. Such a move should yield sharper photos but invites distracting moire in fine patterns.
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.
