K-5 IIs 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.
