Conclusion: For years now, we've heard readers asking the camera manufacturers to offer a camera without an optical low-pass filter in the quest for the maximum possible resolution. Some have seen OLPF-free digicams as something of a holy grail, but the truth of the matter is that removing the low-pass filter is not a magic bullet -- the improvement in per-pixel sharpness is real -- if your lens resolves sufficient detail, anyway -- but so too is the occurrence of moiré and other...
Pros: Sharper, more detailed images than from the K-5 II, Relatively modest price increase compared to the standard model, Widely available online and at Pentax retailers, ...and everything else we praised about the K-5 II
Cons: Prone to moiré, aliasing, and false color, Moiré can be challenging to correct manually if it occurs, Unless you review your images very carefully in the field, you may not notice issues until it's too late to reshoot, Demands pricey, high-quality lenses to make the most of its top-billed feature; consumer-grade glass is unlikely to show much difference even without low-pass filter, ...and everything else we bemoaned in our, K-5 II review
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...
Summary: The Pentax K-5 IIs follows its predecessor by two years with an almost identical specification which hides two critical changes: The removal of the anti-alias filter and the most sensitive autofocus system yet. Yet, until the K-5 IIs arrived, the K-5 was still the image quality champion among APS-C DSLRs. This review of the Pentax K-5 IIs shows that Pentax to deliver a new flagship DSLR which exceeds the K-5.
Pros: Excellent control over image noise, Class-leading retention of details, 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
Excerpt: The Pentax K-5 IIs is outwardly identical to its predecessor, the original K-5, and to its sister model, the K-5 II (the only difference being that the K-5 II has an anti-aliasing filter fitted), so a lot of comments that we made about those cameras apply equally to the new K-5 IIs. The Pentax K-5 IIs is the same size - 97(H) x 131(W) x 73(D) - and the same weight - 660g without the battery or memory card fitted.

Excerpt: Fazit: Pentax bietet die Neuauflage der DSLR K-5 in zwei Versionen an. Das teure Sondermodell K-5 IIs kommt ohne Tiefpassfilter beim Bildsensor aus. Das rechnet sich jedoch nur für echte Schärfe-Enthusiasten, denn die S-Klasse bringt ein Quäntchen mehr Schärfe als das Standard-Modell. Die Ausstattung bietet identisches, sehr gutes Niveau und spricht den erfahrenen Fotografen auf der Suche nach einer robusten DSLR an.
Pros: Hervorragende Ausstattung, Feine Konfigurierbarkeit, Robustes, wertiges Gehäuse, Lange Akku-Laufzeit
Cons: Autofokus im Live-View und bei Video, Video-Funktionen bleibt funktional hinter der preislich ähnlichen Konkurrenz
Excerpt: Kameraproducenterne finder hele tiden på nye måder at tiltrække kunder på. Et bredt udvalg af kunstfærdige filtereffekter kan være rart af og til, GPS-logging kan være nyttigt, og trådløs Wi-Fi-overførsel af billeder er i ved at blive standardudstyr. Men til syvende og sidst koger det ned til, hvor god billedkvalitet du får ud af udstyret. Og som vi alle ved, har billedkvaliteten ikke noget med GPS eller Wi-Fi at gøre, men med samspillet mellem fotografen og værktøjet.
