Summary: One such useful function is the ability to delete JPEG and RAW versions of an image independently from each other. You can shoot video in full HD mode, as well as at 30 and 25 fps, and VGA footage at the same frame rate. Pentax has released a sibling model DSLR, the K-5 IIs, which is identical except for the removal of the anti-aliasing filter in front of the sensor.
Pros: Improved autofocus system, HD and VGA video, Top-notch picture quality, Long battery life
Excerpt: In late 2012, Pentax announced its 2012 flagship DSLR siblings, the K-5 II and K-5 IIs. Both camera models feature a 16.28-megapixel CMOS image sensor, a 3.0-inch LCD display, Pentax's PRIME II imagine engine, a newly designed Autofocus sensor for more accurate performance with faster lenses, a 1/8000 per second top shutter speed, 7 frames-per-second high-speed burst shooting, 9 image modes and 18 built-in digital filters.
Summary: Bearing all that the K-5 II does, minus an optical low-pass filter, the K-5 IIS is a specialized camera made for those who want a little more detail and know how to handle the resulting artifacts. Its weatherproof design and small, tight build make it ideal for landscape photographers, as well as anyone who spends a lot of time outdoors.
Pros: Good detail and dynamic range (even better in Raw), Very 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, In-camera Raw processing, Built-in sensor-shift shake reduction effectively stabilizes all mountable lenses, Useful electr...
Cons: No dedicated movie shooting button (important only if you plan to use the movie mode often), No AF during movie shooting, Poorly implemented live histogram in live view/manual exposure mode (doesn't indicate final exposure), No 'live' aperture control during movie shooting, Shadow Correction mode doesn't take full advantage of K-5's sensor, Jaggies and color error can be a problem along very fine diagonal lines (more so with the K-5 IIS), Noise processing in Raw at IS...
Conclusion: For the last couple of generations of Pentax's K-series flagships, as soon as I've returned the review camera, I've gone out and bought one for myself. For a change, I won't be doing that with the K-5 II -- the changes Pentax has made since the K-5 just aren't significant enough to justify an immediate upgrade for the typical K-5 owner. (If low-light shooting is your bread and butter, though, the K-5 II might be worth your consideration.
Pros: Very sharp, detailed images, Wide ISO sensitivity range, excellent high ISO performance, Very good dynamic range, especially from RAW, 6.7 fps burst mode with generous buffer depth, Compact, comfortable mag-alloy body packed with features, Weather, dust, and cold (14°F) resistant, and so is optional portrait / battery grip, Accurate viewfinder with minimal blackout, Noticeably improved LCD, In-body Shake Reduction, Dual-axis level with horizon correction and compositi...

Pentax perfects the K-5, but faces stiff competition from the Nikon D7100.
21 February 2013
Conclusion: When it was announced at Photokina 2012, the K-5 II was an immediate disappointment for some die-hard Pentaxians, who had been primed by the photo rumor mill for a true follow-up to the K-5. They had hoped for a full-frame K-3, or at least a 24-megapixel APS-C body. What they got instead was a warmed-over K-5, with only a new LCD and improved autofocus. Others, however, were quick to recognize the K-5 II as a smart tactical move.
Summary: That the Pentax K-5 II is a minor upgrade on the Pentax K-5 is not necessarily a bad thing, as the Pentax K-5 was an impressive model in itself. Its headline improvement of a more sensitive AF system is minor although combined with the changes to the LCD screen and the lower launch price (£250 less) it's unquestionably a better proposition than the Pentax K-5 .
Summary: The Pentax K-5 II follows its predecessor by two years with an almost identical specification which hides the most sensitive autofocus system yet. The new SAFOX X AF system is sensitive down to -3 EV which is beyond any available digital camera. The simultaneously-launched K-5 IIs Pentax K-5 IIs which lacks an anti-alias filter is the only DSLR to top the image quality of the original K-5 Pentax K-5 . The K-5 II lands right between them.
Pros: Excellent control over image noise, Very good image sharpness, Superb dynamic-range, Natural image colors, Generally fast and responsive, Good focusing accuracy, Effective stabilization for all lenses, Unique, Unique, Innovative exposure control, Extremely flexible image parameters, Digital white balance preview, Post-shot RAW recovery, In-camera RAW conversion, Top-of-class weather resistance, Great LCD visibility
Cons: Noticeable image review delay, Slow in-camera corrections, Pitch not shown in OVF, Poor, OVF and, LCD too left, Status screen does not turn off automatically, Camera strap gets in way of mode-dial
