K-5 II Body - 16.3 MP, CMOS, ISO 80 - 51200, 3’’ LCD, Full HD
This new model is designed to be the successor to the PENTAX K-5 (launched in October 2010), which has been very well received for its compact but solid, functional body and high-quality image reproduction. As the flagship model of the K series, the K-5 II boasts many advanced functions and user-friendly features, including a newly developed AF sensor assuring a broader AF working EV range, to accommodate many kinds of shooting conditions and photographic requirements.
The K-5 II features a newly developed, highly sensitive SAFOX X AF module. Thanks to the unit’s high-sensitivity AF sensor, which performs brilliantly in low-light conditions, this new module offers a broad AF working EV range (-3 EV to +18 EV). SAFOX X can work with luminous flux based on F2.8 levels in addition to that of F5.6. This increase the AF accuracy drastically when using with very fast lenses Coupled with an upgraded AF algorithm, it delivers exceptional AF performance, including such useful features as a select-area expansion function, which automatically tracks the subject even when it moves away from a pre-assigned select point by assessing distance data collected by neighboring focus sensors.
The K-5 II comes equipped with a 3.0-inch, wide-view, air-gap-free LCD monitor with approximately 921,000 dots. Sandwiched between the front glass panel (which is coated with an anti-glare film) and the LCD screen is a unique resin layer that cuts down the reflection and dispersion of the light to effectively prevent ghost images and greatly reduce brightness loss. The front panel is also made of tempered glass to keep it free of scratches and abrasions.
With its large sensor measuring 23.7mm by 15.7mm in size with approximately 16.28 effective megapixels, the K-5 II’s latest-generation CMOS image sensor assures high-speed image data readout. By coupling this high-performance image sensor with the acclaimed PRIME (PENTAX Real Image Engine) II imaging engine, the K-5 II delivers super-high-resolution, rich-gradation digital images free of digital noise over a wide sensitivity range — from ISO 100 to ISO 12800 in standard setting, or from ISO 80 to ISO 51200 when expanded via a custom function.
The K-5 II features a glass pentaprism finder with a nearly 100% field of view and approximately 0.92-times magnification (with a 50mm F1.4 lens at infinity) to provide a sharp, clear view of the entire image field and improve the accuracy and speed of focusing and image composition. It also comes with the renowned Natural-Bright-Matte III focusing screen to facilitate manual-focus operation.
The K-5 II’s exterior casing is made of sturdy yet lightweight magnesium alloy, while its chassis is made of highly rigid stainless steel. Thanks to the inclusion of 77 special seals in the body, it boasts a dustproof, weather-resistant and cold-resistant construction, assuring reliable operation even under demanding outdoor conditions, and at temperatures as low as -10°C. It also features a dependable shutter unit that provides a top shutter speed of 1/8000 second and the outstanding durability to withstand as many as 100,000 shutter releases.
The K-5 II’s high-speed continuous shooting mode records as many as 30 images (in the JPEG format) in a single sequence at a maximum speed of approximately seven images per second, allowing the photographer to preserve sharp, crisp images of active, fast-moving subjects — such as athletes, stage performers and wildlife — with great ease.
