Summary: The Pentax K-5 is an excellent reflex destined for those who want an advanced model able to guarantee maximum flexibility and quality images. The strength in the body allows you to take it virtually anywhere. Particularly interesting is the fact that it is equipped with a large number of seals that allow it to also be used in dusty environments, with sand or under a light rain.
Pros: Quality of results, Creative features.
Cons: In the second video does not work autofocus.
Excerpt: Pentax has a long history of innovation as well as a rabid fan base that loves the company’s tradition of optical excellence and originality. In fact, this fan base is the reason I’m writing this review. If you’re not already a Pentaxian you probably didn’t know that Pentax (derived from PENTAprism refleX) built the first camera to incorporate a penta-prism viewfinder and reflex mirror system in 1957 and went on to introduce the first TTL metering system in 1964.
Summary: The Pentax K-5's compact, solid body, generally well thought-out ergonomics, comprehensive feature set, and excellent image quality, in both still and movie modes make it one of the best APS-C DSLRs currently on the market.
Pros: Good detail and dynamic range (even better in RAW), Exceptionally low shadow noise in RAW files at low ISOs, One of the best APS-C DSLRs in terms of high ISO image quality, Very good build quality and handling, Maximum ISO of 51,200 at full resolution, Excellent burst depth in RAW mode (with firmware 1.0.1), 1080p HD video mode with basic editing built-in, Useful electronic level and composition adjustment functions, Comprehensive customization options including adjus...
Cons: AF system not as versatile as Nikon D7000 (which is a cheaper camera), Lockable exposure mode dial can be annoying, No dedicated movie shooting button, No AF during movie shooting, Poorly implemented live histogram in live view/manual exposure mode (doesn't show final exposure), No 'live' aperture control during movie shooting, Shadow Correction mode doesn't take full advantage of K-5's sensor, Jaggies can be a problem along very fine diagonal lines
The K-5 is the best Pentax we've tested thanks to a capable new sensor and sharp kit lens.

Conclusion: Much of the K-5’s pre-release hype focused on the brand new 16.2 effective megapixel sensor. In our tests, we found the excitement to be justified. This Pentax matches or exceeds comparable models from Nikon and Canon, especially in the areas of sharpness and color accuracy. Even though there are plenty of hardware, design, and feature similarities to the K-x, the K-r, and especially the K-7; current owners may still want to give the K-5 a look as the upgrade is...
Conclusion: With the launch of the K-7 two years ago, Pentax played to its strengths by creating a digital SLR that was not only feature-rich, but also surprisingly compact for a weather-sealed, magnesium alloy-bodied camera. The K-7 was an important product for the company, providing some truly unique features, and its rugged, coldproof body reinforced Pentax's reputation for catering to the needs of sporty, outdoors types.
Pros: Extremely wide ISO range, excellent high ISO performance, one of the best APS-C sensors yet, Very detailed images and very good dynamic range, especially from RAW, 6.5 fps burst mode has very good buffer depths regardless of file type(s), Unusually compact magnesium-alloy body, but still packed with features, Weather, dust, and cold (14°F) resistant, and so is optional portrait / battery grip, Good control placement, surprisingly comfortable grip even for large hands,...

Conclusion: The weather-sealed Pentax K-5 is a fast-shooting digital SLR with in-body stabilization and fast burst shooting, but it's hampered by an underperforming kit lens, poor high ISO performance, and some other issues.
Summary: The K-5 has set many firsts for Pentax, and has already gotten the Pentax brand mentioned alongside the industry-leaders, Nikon and Canon, all over the web. It is a fantastic DSLR with exceptional image quality, fast autofocus, high sensitivity, a compact and lightweight design, weather-sealing, and shake reduction backwards-compatible with old lenses even from the screw-mount era.
Pros: Superb image quality, Excellent for low-light photography (ISO 80-51,200), Weather sealed, Easy-to-use interface with many buttons, Good overall performance, Compatible with thousands of lenses, Very reasonably priced, AF system improved over the K-7
Cons: Records video in .AVI format, Poor selection of video framerates, AF is not as good as that of the competition, Too small for some hands without battery grip
Summary: If you’re a Pentax owner looking to step up, the K-5 is a worthy upgrade from the K-7 or any other Pentax DSLR. You’ll get a noticeable amount of added resolving power, at least an extra stop of usable ISO, and if you don’t mind noise, sensitivity up to ISO 51,200. Plus, the burst rate has been ratcheted up, to 7 fps over the K-7’s 5.2 fps.
Excerpt: FROM OUR EDITORS AT PHOTOKINA: Housed in the same the exact water-resistant, cold-sealed body, the all-new Pentax K-5 is more of an upgrade to Pentax’s flagship prosumer camera, the K-7, than a new camera all together—but despite the lack of noticeable changes on the outside, it is what's on the inside of the K-5 that counts.
