With 77 special seals applied to the body, it also features a dustproof, weather and cold-resistant construction, ensuring reliable operation even under harsh conditions and at temperatures as low as -10°C. It also features a newly designed shutter unit providing a top shutter speed of 1/8000 second and the outstanding capability to withstand 100,000 shutter releases.
2. Optical viewfinder featuring approx. 100% field of view
The K-7’s glass prism finder offers approximately 100% field of view along with approximately 92% magnification to facilitate focusing and framing operations. It also features a new Natural-Bright-Matte III focusing screen to improve focusing accuracy during manual-focus operation.
3. High-speed continuous shooting at approx. 5.2 images per second
The K-7’s high-speed continuous shooting mode captures as many as 40 images (in JPEG recording format) at a maximum speed of approximately 5.2 images per second, allowing the photographer to follow the movement of an active subject or preserve a sequence of the subject’s expressions.
4. New DR II mechanism to minimise dust spots
The K-7 comes equipped with the newly developed DR (Dust Removal) II mechanism, designed to effectively minimise annoying dust spots on recorded images, even after changing lenses in dust-prone outdoor settings. The K-7’s unique dust-alert system also lets the user check for dust on the filter prior to actual shooting.
5. High-quality image reproduction
(1) Approximately 14.6 effective megapixels for true-to-life image reproduction
The K-7 incorporates a newly developed CMOS image sensor measuring 23.4mm by 15.6mm featuring a high-speed, four-channel image data read-out. With approximately 14.6 effective megapixels, this image sensor can faithfully and accurately reproduce fine-detailed, gradation-rich images. With the adverse effects of digital noise greatly reduced, the sensitivity can be increased from ISO 100 up to the highest level of ISO 6400 (via a custom function).
(2) High-performance, high-speed PRIME II imaging engine
The K-7 features the newly developed PRIME (PENTAX Real Image Engine) II as its imaging engine, an upgrade of the original PRIME,. This new imaging engine offers greater data-processing speed and produces improved quality images with richer gradation and more accurate colour rendition. It also offers high-speed movie data transmission.
6. New 77-segment multi-pattern metering
Newly developed for the K-7, a sophisticated 77-segment multi-pattern metering system greatly improves light-metering accuracy. By accurately analysing various types of data (such as the image’s composition and format between upright and horizontal, and the subject’s distance and magnification) transmitted from the sensors in the camera body, this system greatly improves the accuracy of exposure control.
7. New-generation SR mechanism for improved shake-reduction effect
The K-7 features the PENTAX-developed SR (Shake Reduction) feature, which effectively minimises the adverse effect of camera shake by approximately 2.5 to 4 shutter steps, assuring sharp, blur-free images even under demanding shooting conditions. This innovative feature is compatible with all PENTAX interchangeable lenses — including a selection of the lenses designed for film-format cameras.*
* Lenses compatible with this mechanism are the PENTAX K-, KA-, KAF-, KAF2- and KAF3-mount lenses; screw-mounted lenses (with an adapter); and 645-and 67system lenses (with an adapter). Some functions may not be available with certain lenses.
8. Live View real-time, on-display image confirmation with Face Recognition AF and high-speed continuous shooting modes
The K-7 features the Live View function, which allows the user to view the image on the LCD monitor during shooting. You can take advantage of this convenient function not only in the Contrast AF mode, which optimizes the focus based on the subject’s contrast, but also in the Face Recognition AF mode, which automatically and accurately focuses on the subject’s face.
9. High-quality still image recording at 1280 x 720 pixels; 30-frames-per-second movie recording at HD-television proportions
The K-7 adds a new movie recording function, extending the benefits of SLR photography to the world of movie shooting. Beautiful movie clips can be recorded at various sizes — 640 x 416 pixels, 1536 x 1024 pixels, or 1280 x 720 pixels (16:9 high-definition TV proportions) — at a frame rate of 30 frames per second. The K-7 is also equipped with an HVMI terminal and an external microphone input terminal.
10. New 11-point wide-frame AF sensor
The K-7’s new SAFOX VIII+ wide-frame autofocus system features 11 sensor points (with 9 cross-type sensors positioned in the middle). This AF system ensures reliable, responsive autofocus operation superior in speed and accuracy to the previous system. The K-7 also incorporates an AF-assisted spotbeam projector in its built-in flash unit to improve autofocusing accuracy in the dark.
11. Custom Image function to easily create desired visual effects
The K-7’s Custom Image function allows the user to provide a finishing touch to an image by highlighting the ambience of the scene. The user can select one of seven modes, including the new “Muted” mode designed to recreate an image with delicate, subdued colours. In addition to saturation, tone, contrast and sharpness — the functions previously available — it is now possible to adjust “key” and “contrast highlight/shadow” to the desired levels. The effects of these factors can be effortlessly confirmed on a preview image using the Digital Preview or Live View function before finalising the settings.
12. Versatile exposure system for faithful reproduction of creative intentions
(1) Hyper Programme function
The K-7’s Hyper Programme function allows the user to instantly switch from the Programmed AE mode, to the Shutter or Aperture-Priority AE mode with a simple turn of the electronic dials on the grip.
(2) Hyper Manual function
When shooting in Manual mode, a single push of the green button allows the user to instantly set the proper exposure for the subject.
(3) Sensitivity-Priority mode
The K-7 features a unique Sensitivity-Priority (Sv) mode, designed to automatically select the optimum combination of aperture and shutter speed for a user-selected sensitivity. The sensitivity can be shifted instantly in 1/2 or 1/3 steps by turning the electronic dial on the back panel.
(4) Shutter/Aperture-Priority mode
The Shutter/Aperture-Priority (TAv) mode automatically selects the most appropriate sensitivity for a user-selected shutter-speed/aperture combination. It allows the user to experiment with a greater range of photographic expressions simply and effectively.
13. Large, easy-to-see 3.0-inch wide-view LCD monitor with approximately 920,000 dots
The K-7 features a large 3.0-inch colour LCD monitor with approximately 920,000 dots on its back panel. Its wide-view design allows the photographer to check the monitor image from approximately 170 degrees both vertically and horizontally, facilitating low- and high-angle shooting using the Live View function.

Paris, France – 15th May 2009 – DxO Labs announces the immediate availability of 83 new DxO optical correction modules, adding to the 100 modules recently published. These additions now extend DxO Optic Pro’s range to include over 1,200 modules covering all types of lenses on the market: fisheyes, wide-angles, zooms, and super telephotos, and most major brands (Canon, Konica-Minolta, Nikkor, Pentax, Samsung, Sigma, Sony, Tamron, Tokina, Carl Zeiss). Over the last 5 years, DxO Labs has been analyzing camera/lens combinations so as to provide corrections that are specific to each lens. For example, DxO Optics Pro corrects the geometric distortion and compensates for the vignetting of wide-angle lenses; it increases the sharpness and corrects the chromatic aberration for telephoto shots. To achieve such results, DxO Labs’ engineers and expert photographers have interpreted hundreds of thousands of images representing all possible configurations of the cameras in use (focal length, aperture, sensitivity, etc.).
