Top-of-the-line model PENTAX Q series
Developed as the top-of-the-line model of the PENTAX Q series, this new model is equipped with an image sensor much larger than those of its sister Q-series models for upgraded image quality, while retaining the super-compact, ultra-lightweight body that comfortably fits in the photographer’s palm.
Launched as the flagship model of the popular PENTAX Q series , the PENTAX Q7 offers casual, carefree digital-SLR-quality photography to everyone. Thanks to a new 1/1.7-inch, back-illuminated CMOS image sensor — the largest in the Q series — the Q7 delivers image quality that exceeds its sister models. It also offers a host of the advanced features expected in a top-of-the-series model, including high-sensitivity shooting at a top sensitivity of ISO 12800 (compared to ISO 6400 for the Q10); improved shake-reduction performance; reduced operation time lag at start-up and between exposures; and effortless, user-friendly operation. In addition, it features an array of creative tools such as Bokeh Control and Smart Effect, which assist the photographer in easily creating more personalized images.
Extra-large 1/1.7-inch image sensor — the largest in the Q series
Thanks to the incorporation of a new 1/1.7-inch, back-illuminated CMOS image sensor, the PENTAX Q7 boasts the finest image quality in the Q series.
By coupling this image sensor with the state-of-the-art Q ENGINE high-speed imaging engine, the Q7 not only offers high-sensitivity shooting at an ISO 12800 and delivers beautiful images with faithful reproduction of gradation and texture, it also minimizes annoying noise effectively at all ISO sensitivity levels. Its autofocus accuracy during low-illumination shooting has also been improved, assuring pinpoint focus on the subject even at the faintest light level of EV 0. Because of its larger sensor, the angle of view for the Q7 is wider than that of its sister models, even when the same lens is mounted.** When the 02 Standard Zoom lens is mounted, for instance, the angle of view is 23mm to 69mm in the 35mm format (compared to 27.5mm to 83mm for the Q10). Likewise, when the Adapter Q for K-mount Lenses is used with the Q7, the focal length of the mounted lens is extended by approximately 4.6 times (compared to approximately 5.5 times for the Q10).
* With Q-mounted lenses, the shift in angle of view may vary depending on the lens type.
Thanks to the incorporation of a new Q ENGINE which provides a 10% improvement in clock frequency compared to existing engines, and optimized algorithm, the Q7 provides a shortened start-up time lag of approximately one second. It also means much-improved response during shooting, such as a shortened time lag between exposures, making camera operation more comfortable and flawless in all types of shooting. The Quick Dial, to which the photographer can assign as many as four favourite functions, is more versatile and functional than ever, with the addition of AF/MF switching, focus assist ON/OFF and ND filter ON/OFF to the list of assignable functions.
Dependable SR mechanism
Featuring a latest gyro sensor, the Q7’s upgraded SR (Shake Reduction) mechanism compensates camera shake by as much as three shutter steps. As a result, the Q7 produces sharp, blur-free images even under conditions prone to camera shake, such as when using a telephoto lens, shooting in the dark without flash illumination, or capturing landscapes in the twilight.
High-quality, Full HD movie recording
Thanks to the improvements in the image-processing algorithm, the Q7 captures beautiful Full HD movie clips (1920 x 1080 pixels, at 30 frames per second, in the H.264 recording format) with minimal noise, even during high-sensitivity recording at ISO 12800. A new interval HD movie recording function adds more creativity to visual expression. The user can also take advantage of advanced image-processing tools including the Smart Effect modes,** an array of in-body movie editing tools, and autofocus operation during movie shooting.
* The frame rate may vary when a selected Smart Effect mode requires nonstandard image processing.
