The Pentax K7 features a 14.6MP CMOS sensor, measuring in at 23.4mm by 15.6mm, and featuring a high-speed, four-channel image data read out. Said sensor boasts an ISO range of 100 to 6400, with the highest setting offered through a custom function. The K-7 is also the latest DSLR to offer HD video capture. Video is captured at 1280 x 720 pixels and at 30fps, while also boasting an HVMI terminal and external microphone input. The K-7 also features a 3in LCD screen, offering a 920k dot resolution. Another highlight for the K-7 is the speed of its continuous shooting. The model is capable of capturing at approximately 5.2 fps for up to 40 shots.
1. Durable and functional body, smaller than any other in its class
The K-7 is built exceptional solid and durable, as its chassis is made of high-rigidity stainless-steel alloy and its housing is made of durable but lightweight magnesium-steel alloy. Thanks to 77 special seals applied to the body, it also features a dustproof, weather- and cold-resistant construction, assuring reliable operation even under harsh conditions and at a temperature 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 durability to withstand 100,000 shutter releases. Despite all these features, the K-7 is one of the most compact and functional mid-class models in the market, because PENTAX applied all the experience and expertise in camera downsizing the company has developed from the earliest days of film-format SLR cameras.
2. Optical viewfinder showing nearly 100% field of view
The K-7's glass prism finder offers an approximately 100% field of view and an 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 minimize dust spots
The K-7 comes equipped with the newly developed DR (Dust Removal) II mechanism, designed to effectively minimize annoying dust spots on recorded images, even after changing lenses in dust-prone outdoor settings. By shifting the low-pass filter located in front of the CMOS image sensor at supersonic speed using a piezoelectric element, it shakes the dust off the low-pass filter as effectively and efficiently as any other dust removal device. The K-7's unique dust-alert system also lets the user check for dust adhering to the low-pass filter prior to actual shooting.
5. High-quality image reproduction
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 analyzing 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) mechanism, which effectively compensates the adverse effect of camera shake by approximately 2.5 to four shutter steps, assuring sharp, blur-free images even under demanding shooting conditions. This innovative mechanism is compatible with all PENTAX interchangeable lenses - even most of the lenses designed for film-format cameras. Since this new-generation version can freely shift the image-sensor unit to keep it level regardless of the camera's inclination, it also provides such user-friendly new functions as automatic level adjustment and minute angle adjustment (in the direction of up/down, right/left and clockwise/counterclockwise), helping to compose the image exactly the way the photographer wants.
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. Thanks to the newly developed diaphragm-control mechanism, the Live View function can also be used in the continuous shooting mode with the mirror at lock-up position.
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: For instance, reduce the depth of field to make the subject stand out, or use different lenses to create distinctive visual effects. Beautiful movie clips can recorded at different 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 nine cross-type sensors positioned in the middle). By adding a light source type to its data range, and driven by a greatly improved algorithm, this AF system assures reliable, responsive autofocus operation superior in speed and accuracy to the previous system. The K-7 also incorporates an AF-assisting 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 lets the user control the image's finishing touch to capture their photographic intention, or reproduce the ambience of the scene. With the K-7, the user can select one of seven modes, including the new ''Muted'' mode designed to recreate an image with delicate, subdued colors. In addition to saturation, tone, contrast and sharpness - the factors 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 finalizing the settings.
12. Versatile exposure system for faithful reproduction of creative intentions
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 color 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.
14. Powerful rechargeable battery
The K-7 is powered by a large-capacity, rechargeable lithium-ion battery, which can capture approximately 980 images when fully charged.

Comments about Pentax K-7 Digital SLR Camera Body:
Just getting to grips with this camera, got it before Christmas but early signs are good. It's light, the controls are easy to use and the screen is bright and clear. I especially like the changes from the K20, better ISO accessability, the HDR finction and the HD video is excellent.White balance and contrast seem better and having compared to a friends Nikon in some conditions I think the pictures are better.I would recommend this to anyone who wants to be a little less mainstream, wants a compact Pro DSLR and wants the extras such as HDR and HD Vid.
Bottom Line Yes, I would recommend this to a friend
