Good points:
Easy to use, Simple design, plenty of features, Great quality photos. Its been pretty easy to learn to use, although i'm still finding out how to do things! It also has a really satisfying clunk when you take a photo - not great if you want to be quiet but it makes it feel very different to a point and shoot digital.
The lenses are great too. The 55-200mm is a brilliant zoom lens, pictures are great (ive been using this for sports photography and it takes some great shots. really crisp.)
Bad points:
Changing the settings (ie changing the shutter priority when on that particular setting) is not particularly logical and whilst the manual is very comprehensive, its an intimidating read!
The delete button is combined with the flash release button. Whilst this doesn't conflict most of the time, its not the greatest design feature.
I cant really find too many faults with the camera, im a beginner and dont have anything to compare it too! but ive been really happy with it so far.

John , Bishopsteignton, Devon Keen amateur

Score 9.0/10
Good points:
I compared this to the K-R and simply couldn't justify the additonal cost of K-R for the features offered.
I previously owned a manual SLR and it is pretty easy to use the K-X in the same way which I rather like but may not be to everyones taste.
The range of features is exetensive but I haven't explored them all yet
Bad points:
Some of the features I wanted were rather buried in the menu system and hard to find but so far I haven't found anything that I can't do.

Kevin, Bristol Keen amateur

Score 9.0/10
Good points:
This is my first dSLR so I am still getting used to the jump up from a bridge camera. I am noticing an immediate improvement in image quality.

A paper manual is supplied which gives extensive instructions on the different functions of which there are many. As a reasonably experienced amateur I am finding all of the features I had hoped for, and some unexpected ones.
Bad points:
Not necessarily a downside, more a point of note. In moving from a camera with an EVF to a "real" viewfinder I find that the functionality in the display is much reduced from that available with my old EVF, for instance, I have to check the rear screen for a histogram rather than see it in the viewfinder. This means that I have to work differently and I guess it's all part of the learning process that comes with a different technology.

Manufacturer's Description

12.4MP resolution and HD movie combine to make this a 5 star camera

The K-x combines a variety of advanced features and user-friendly functions to ensure an outstanding level of photographic performance within a compact, lightweight body.

The K-x design is based on the award winning PENTAX K-m, an entry-class digital SLR camera launched in October 2008 that gained popularity for its compact, lightweight body and simple, user-friendly operation. The K-x features a newly designed high performance CMOS image sensor and an upgraded filter function. It also features a whole host of advanced features and such as live view shooting and movie recording, approximately 12.4 megapixels and high-speed continuous shooting. The K-x is the perfect camera for first-time digital SLR camera users, as well as an ideal backup camera for more experienced photographers.

Main Features of the PENTAX K-x:

1. High-quality image reproduction
(1) Approximately 12.4 effective megapixels for true-to-life image reproduction
The K-x incorporates a newly developed CMOS image sensor to assure high-speed image data read-out at varying ISO sensitivity levels. With approximately 12.4 effective megapixels, this image sensor can reproduce true-to-life images with fine detail and rich depth of colours. The K-x also offers a wide sensitivity range between ISO 200 and ISO 6400 and allows the user to expand the sensitivity range between ISO 100 and ISO 12800 via a custom function, giving greater creative freedom.

(2) High-performance, high-speed PRIME (PENTAX Real Image Engine) II imaging engine
Thanks to new technologies supplied by Fujitsu Microelectronics Limited, this new imaging engine offers greater data processing speed and enhanced capability to produce higher-quality images with richer, more accurate colour rendition, as well as faster transmission speed of movie data.

2. Compact, lightweight body
Despite the incorporation of the large 23.6mm x 15.8mm image sensor, the K-x is one of the most compact, lightweight digital SLR cameras in its class.

3. Live View function, with Face detection of up to 16 faces
The K-x features a live view function, which allows the user to view the image on its LCD monitor during shooting. The K-x also offers a choice of three different focusing modes during live view shooting: Contrast AF, which optimises the focus based on the subject’s contrast; Face Detection AF, which automatically detects up to 16 faces, selects the main subject’s face from multiple faces, then captures it in sharp focus; and Phase Difference AF, which uses the AF sensor positioned in the camera body to optimise focus on the subject.

4. High-quality recording at 1280 × 720 pixels, with HDTV-proportion movie recording at 24 frames per second
The K-x provides a movie recording function* which captures beautiful, true-to-life movie clips in 16:9 high-definition TV proportions (1280 × 720 pixels) at a frame rate of 24 frames per second. This extends the benefits of high-quality SLR photography to the world of movie shooting.

5. PENTAX-original SR mechanism for sharp, blur-free images
The K-x features the PENTAX-developed SR (Shake Reduction) mechanism. This innovative mechanism extends its benefits to almost all PENTAX interchangeable lenses – even those designed for film-format cameras.** Thanks to this mechanism, the K-x produces sharp, blur-free images even under demanding conditions prone to camera shake, such as when using a telephoto lens, shooting in the dark without a flash illumination, and taking pictures of sunset scenes.

  • Lenses compatible with this mechanism: PENTAX K-, KA-, KAF-, KAF2- and KAF3- mount lenses; screw-mounted lenses (with an adapter); and 645- and 67-system lenses (with an adapter). Some functions may not be available with certain lenses.

6. High-speed continuous shooting at approximately 4.7 images per second
The K-x’s high-speed continuous shooting mode records as many as 17 images (in JPEG recording format) at a maximum speed of approximately 4.7 images per second – the fastest of all entry-class models. The K-x also features a new, reliable shutter unit, which proved its dependability and ruggedness through a demanding action test of more than 100,000 shutter releases. Its top shutter speed of 1/6000 second allows the photographer to preserve sharp, crisp images of fast-moving subjects.

7. Innovative image processing functions to produce distinctive photographic expressions

(1) Digital filter function

Realize the essence of SLR photography. Equipped with sophisticated features for top quality photography
Watch this movie shot exclusively with PENTAX K-7 and PENTAX lenses:

The PENTAX K-7 lens-interchangeable digital SLR camera. Despite its compact, lightweight body, this new model brings together a wide array of advanced functions and user-friendly features with outstanding reliability and operability. This makes it possible to enjoy high-quality digital SLR photography with great ease.

The K-7 has been developed as a high-end model of the PENTAX K digital SLR camera series. True to its series concept, it was designed not only to assure outstanding image quality, but also to provide exceptional ease and comfort of operation and the utmost satisfaction to photo enthusiasts of all levels, including advanced amateurs. After making a thorough review of all essential digital SLR camera components and functions, PENTAX has revised and upgraded many of them, including viewfinder, shutter unit, continuous-shooting capacity, and exposure and autofocus systems. Protected by a durable, high-quality metallic body, but the K-7 is designed to be extremely compact and functional – just like all other K-series models – for enhanced portability and maneuverability. In addition, it has added several user-friendly features, including video recording, high dynamic range (HDR), and automatic horizon correction. All of these make the K-7 a tremendous photographic tool, perfect for all discerning digital SLR photographers.

Major Features
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
(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 and featuring a high-speed, four-channel image data readout. 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) without worry.

(2) High-performance, high-speed PRIME II imaging engine
The K-7 features the newly developed PRIME (PENTAX Real Image Engine) II, an upgrade of the original PRIME, as its imaging engine. This new imaging engine offers greater data-processing speed and produces better-quality images with richer gradation and more accurate color 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 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.

  • 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 67-system 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. 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 × 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 × 416 pixels, 1536 × 1024 pixels, or 1280 × 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
(1) Hyper Program function
The K-7’s Hyper Program function allows the user to instantly switch to the Shutter- or Aperture-Priority AE mode from the Programmed AE mode, with a simple turn of the electronic dials on the grip. To return to the Programmed AE mode, simply press the green button positioned next to the shutter release button.
(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, which is 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
Taking full advantage of the unique capability of digital cameras permitting automatic shift of sensitivity at any time, 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 with great ease.

13. Large, easy-to-see 3.0-inch wide-view LCD monitor with approximately 921,000 dots
The K-7 features a large 3.0-inch color LCD monitor with approximately 921,000 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.

  • Under testing conditions prescribed by PENTAX, when using a rechargeable D-LI90 lithium-ion battery with no flash.

15. Other features
