12.4 effective megapixels
The K-x incorporates a newly developed CMOS image sensor to assure high-speed image data readout and more flexibility with varying ISO sensitivity levels. With approximately 12.4 effective megapixels, this image sensor accurately reproduces true-to-life images with fine detail and rich color depth. The
K-x offers a wide sensitivity range between ISO 200 and ISO 6400 and allows users to expand the sensitivity range between ISO 100 and ISO 12800 via a custom function to offer greater creative freedom to photographers.

Compact, lightweight body
The PENTAX K-x is one of the most compact, lightweight digital SLR cameras in its class. The stainless-steel chassis and overall design offer a space-efficient layout.

Widescreen HD movie recording at 1280×720 pixels at a cinematic 24 frames per second (720p24)
The PENTAX K-x movie recording function*1 captures true-to-life movie clips in 16:9 high-definition TV proportions (1280 x 720 pixels) at a frame rate of 24 frames per second. Compatible with every PENTAX interchangeable lens ever made, the Video Capture mode opens a new world of creativity for PENTA K-x owners.

PENTAX-original SR mechanism for sharp, blur-free images
The Pentax K-x features the PENTAX-developed Shake Reduction mechanism that effectively compensates for the adverse effects of camera shake by as much as four shutter steps. This innovative mechanism extends its benefits to all PENTAX interchangeable lenses — even those designed for film-format cameras.*2 With this SR mechanism, the K-x produces sharp, blur-free images even under demanding conditions such as telephoto lens photography, shooting in dark or low-light setting without a flash illumination, and sunset scenes.

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. This is the fastest of all entry-class models. The K-x also features a more reliable shutter unit, which passed a demanding action test of more than 100,000 shutter releases. The top shutter speed of 1/6000 second allows the photographer to preserve sharp, crisp images of fast-moving subjects.

High-performance, high-speed PRIME II imaging engine
The K-x features the newly developed PRIME (PENTAX Real IMage Engine) II, that is an upgrade of the original PRIME imaging engine. This new imaging engine offers greater data processing speed and enhanced capability to produce higher-quality images with richer, more accurate color rendition, as well as faster transmission speed of movie data.

Live View function with Face detection of up to 16 faces
In addition to the camera’s viewfinder, the camera features a Live View function that allows users to view subjects on the LCD monitor during shooting. The K-x also offers a choice of three different focusing modes in Live View:
Contrast Auto Focus optimizes the focus based on the subject’s contrast.
Face Detection Auto Focus automatically detects up to 16 faces, then selects the main subject’s face from multiple faces, and captures it in sharp focus.
Phase Difference Auto Focus accesses the AF sensor positioned in the camera body to optimize focus on the subject.

Innovative Image Processing Functions

Digital Filter function
The cameras’s digital filter function allows users to process recorded images in a variety of creative ways within the camera and produce highly creative visual expressions. With a choice of 16 different filters including Color Extract, Retro, Soft, Starburst, Toy Camera, and more (including a custom filter for building multiple effects), photographers may apply multiple filters to a single image for customized effects.

Cross Process mode
The camera features a new Cross Process mode that automatically and randomly adds finishing touches to exposures to create eye-catching images with unique, intriguing colors (just like images treated with Cross Process*3 in film photography). This mode adds a whimsical element to digital photography since photographers don’t know the results until the captured image is actually displayed on the camera’s LCD monitor.

High-precision 11-point AF sensor
The high-precision, wide-frame SAFOX VIII autofocus system of the camera features 11 sensor points (with nine cross-type sensors positioned in the middle) to automatically capture even off-centered subjects in sharp, crisp focus. Photographers also may select one of the sensors as a focusing point to accommodate specialized applications.

REVIEWS

DCRP writes:

“Despite a few flaws, most of which are minor, the Pentax K-x is an impressive entry-level digital SLR. It brings very good image quality (especially with a decent lens), snappy performance, tons of features, HD movie recording, and good build quality to the table for under $650 (with a lens). If you’re looking for your first digital SLR, then the camera should be high on your list.”

The camera features a Face Detection function which is effective for capturing casual snapshots of people by optimizing the focusing and exposure of up to 32 faces in a single image in approximately 0.03 seconds. The  X90 megazoom camera also offers other user-friendly functions including Smile Capture which automatically releases the shutter the instant it detects the subject’s smile, and Blink Detection which warns the photographer when the subject’s eyes are closed at the moment of capture.

The Pentax X90 features also the upgraded Face Detection AF & AE function, which automatically detects up to 32 faces in the image field in a mere 0.03 seconds and captures them in great accuracy and with superb clarity, even when the faces are tilted or turned sideways. It also offers a new Small Face filter, which makes the subject’s face appear slightly smaller than in reality in recorded images. In addition, the X90 offers other user-friendly functions designed to produce beautiful portraits with ease: the Smile Capture function, which automatically releases the shutter the instant it detects the subject’s smile; and the Blinking Detection function, which warns the photographer when the subject’s eyes close at the time of shutter release.

The build quality is still up to Pentax’s usual high standard, with tight panel joins and a strong metal hinge on the battery/card hatch. The large comfortable handgrip has a textured rubber surface, and there is a textured rubber thumbgrip on the back. The control layout is well designed with large clearly labelled buttons, and the camera is very comfortable and pleasant to handle. The LCD monitor is nice and sharp, and bright enough to work well outdoors even in bright sunlight. It has a good angle of view in every direction except downwards, annoying really because that’s one direction you need a wide view, for shooting over obstacles.

The Pentax X90 incorporates the PENTAX-original CCD-shift-type SR (Shake Reduction) system to assure sharply focused, blur-free images even under demanding photographic conditions prone to camera shake, such as when using the zoom lens’s super-telephoto range or when shooting a sunset or indoor scene with incident light only.

The X90 offers plenty of features, but most of them are exactly the same as the X70. Externally it’s hard to tell the two cameras apart. The overall body design is almost identical, apart from the X90′s slightly longer lens barrel with a totally cosmetic knurled ring around the end of it. The colour is different too; where the X70 was available in matt black only, the X90 is an attractive blue-grey colour with a slight crackle finish.

The X90 digital SLR camera captures high-quality movie clips, equivalent in image quality to that of high-definition TV (1280 x 720 pixels), in 30 frames per second. It also features the Movie SR (Shake Reduction) mode, which effectively minimizes annoying camera shake during movie shooting through the use of exclusive software. As a result, the photographer enjoys high-quality, blur-free movie shooting with minimal effort. It is even equipped with an HDMI micro terminal for audio/video signal output, allowing the enjoyment of high-resolution movies simply by connecting the camera with a high-definition TV monitor.

This SLR has a combination of approximately 12.1 effective megapixels, a sophisticated imaging engine and a high-quality PENTAX zoom lens, the X90 delivers super-clear, high-quality images. It even allows the photographer to choose the preferred finishing touch from Bright, Natural or Monotone.

The X90 features the advanced Auto Picture mode, which automatically selects the most appropriate shooting mode for a given subject or scene by detecting the subject’s lighting and other conditions. This user-friendly mode not only makes the right mode choice for the photographer from Landscape, Portrait, Night Scene, Night Scene Portrait, Flower, Sport or Standard modes, but also features an auto macro mode, which automatically switches the camera’s focus range to macro in close-range applications.

Reviews

Pocket-lint  writes:

 “In operation the X90’s 9-point AF takes just over a second to determine focus and exposure with a half press of its shutter release button… Like its zoom range, ISO sensitivity is also respectably broad, stretching from ISO 80 through to ISO 6400, though performance is in fact fairly average.”
Rating: ★★★★☆

PhotographyBlog writes:

“The camera handled chromatic aberrations excellently during the review, with very limited purple fringing present around the edges of objects in high-contrast situations… in terms of light sensitivity, up to ISO 800 the X90’s performance is pretty good, though detail is beginning to soften at ISO 800.”

DCI writes:

“The X90 is also quite easy to use, with great button implementation and a simple, easy-to-navigate menu system. One significant downside to the camera is its diminutive size, which is great for portability, but not for comfort.“

ImagingResource writes:

“In the end, even though I wanted to love it for its design, the Pentax X90’s performance stifled any affection. Any way you spell it, the Pentax X90 is close but gets no cigar. The Pentax X90 is not a bad camera by any means, but we’d steer you toward others for better quality and performance for the price.”

MacWorld writes:

“In terms of picture quality, sensor shift anti-shake is fairly good at preventing blur when shooting at the maximum optical telephoto setting or in low light, although images appear quite noisy and lose detail at ISO1600 and above.”

Good: Broad focal range throws up a wealth of compositional choices, well placed and responsive buttons and controls, speedy in operation

Bad: Optical zoom not accessible when recording movies, average low light performance, plastic-y if solid feel

“The 645D will no doubt attract a niche audience, though its almost-£10k price tag is firmly out of reach for the majority. The experience of using a medium format digital camera is very different from a DSLR and has many advantages, especially for landscape photographers. To be clear: the 645D is less of a studio camera than its competition, but its weather-sealed single body design firmly fixes it as one to use in the field or where large, resolute files are a must. However the vertical run shutter, non-customisable construction and no tethered shooting ability may pose issues for certain users.  However its handling is a winner and easy to pick up. For general use a pro-level DSLR still has more versatility but, so long as speed’s no issue, the Pentax 645D is a pleasure to use.”

ephotozine.com writes:

“If I had to judge the cameras on image quality alone then the Pentax would be a clear winner. Unfortunately life isn’t that straightforward, and as the Canon excels in some areas and the Pentax is superior in others I find it impossible to choose a clear winner in this comparison. Your choice will depend on what you shoot, at the end of the day.”

pentaxforums.com reviews writes:

“Some might say that for a medium-format camera, the 645D is relatively cheap and therefore must be second rate.  This isn’t the case, however.  Instead of cutting corners when it came to image quality and core design, Pentax decided to re-use many components from their K-7 (such as the LCD screen, firmware, and processor) in the 645D in order to keep costs down.”

Reviews

PopPhoto reviews the Pentax K-5 and writes:

“the K-5 keeps noise to a Low or better rating up to ISO 400. It remains in acceptable territory up to ISO 1600 and just barely edges into an Unacceptable rating at ISO 3200. Even a judicious use of noise reduction will bring that into our acceptable range without a serious effect on resolution, which remains at an Excellent rating up to ISO 12,800 using Pentax’s default noise-reduction settings “
Rating: N/A

ExpertReviews writes:

“While the K-5 excels for stills photography, it can’t quite compete on value with the Canon 60D and Nikon D7000. Its weather proofing is useful but we’d rather take its competitors’ larger zoom ranges, more capable video modes and the Canon’s articulated screen or the Nikon’s superior autofocus.”

“Overall, a good performance for the Pentax K5. It retains excellent detail for quite a run of large print sizes, which makes for easy cropping from lower ISO settings and the ability to squeeze a 4×6 out of its highest ISO setting of 51,200, great for indoor low-light snapshots. “

“At the lower ISO settings the K-5 provides quality that can easily rival the Canon 60D and Nikon D7000. Where it gets extra special, however, is in the mid-high ISO settings where the processing does an exceptional job of keeping colour noise to a minimum. Granted this is going to be at the expense of sharpness as the ISO increases, but up to ISO 3200 images can still be taken of an acceptable quality.“

The Pentax K-r features a large, 3″ high-resolution color LCD monitor with approximately 921,000 dots. The Pentax K-r DSLR is equipped with a spotbeam projector to assist the AF system in poorly lit locations.

The compact, lightweight Pentax K-r is easy to use with Auto Picture, Scene, and Custom Image Processing modes that take the guesswork out of shooting stunning images while still offering a high degree of manual and priority control. The Pentax K-r DSLR offers a variety of new and improved features including a fast framerate, high ISO sensitivity, responsive autofocus, an improved 12.4 megapixel low-noise sensor and widescreen HD video capture that take it a step above an entry-level DSLR camera.

This camera has a deep, contoured handgrip on the right-hand side, coated in a rubberized compound to aid grip, that enabled me to use three fingers to hold it and my right forefinger to operate the shutter button. There is a generous contoured area where your right thumb sits, with the rest of the body finished in a textured matt black plastic. The K-r thankfuly dispenses with the rather strange, thin and cheap-looking silver rim that runs around the K-x, making it look like a more serious proposition.

The Pentax K-r DSLR incorporates a new generation CMOS image sensor with 12 megapixels and the high-performance PRIME (Pentax Real Image Engine) II imaging engine for accurate and high-speed data processing equal to that of upper-level Pentax digital SLR  models for high-quality images. The Pentax K-r DSLR camera also offers a wide sensitivity range between ISO 200 and ISO 12800 that may be expanded from ISO 100 to ISO 25600 via a custom function.

The K-r is the first Pentax digital SLR camera, and indeed the first DSLR, to feature the IrSimple high-speed infrared data transmission system, the sensor for which is built-into the handgrip. This allows wireless image transfer from camera to camera, or from camera to a web page via a mobile phone, allowing easy sharing with other K-r users and perhaps more usefully uploading downsized images to the web.

It features the same high-speed PRIME (PENTAX Real Image Engine) II imaging engine as the K-7 and K-x. It takes less than a second to store a single JPEG image at the highest quality setting with no discernible lockup between taking shots, allowing you to keep shooting as they are being recorded onto the memory card. For single RAW images the Pentax K-r is just as fast, again with no lockup between shots. In the fastest continuous shooting mode you can hold down the shutter button and take a very speedy 6 frames per second for up to 25 JPEGS or 12 RAW files, or there’s a slower 2fps mode available which allows you to shoot JPEGs until the memory card becomes full or 36 RAW files. This makes the K-r the quickest Pentax DSLR camera and also one of the quickest in its class in terms of continuous shooting speed.

The rear screen doubles as a comprehensive status display, which can be called up by pressing the OK button in record mode. If you then press the INFO button, you can also change all the settings right on the screen using a combination of the navigation pad and the rear e-dial. This ingenious solution spares you the pain of having to enter the menu, and makes most setting changes very simple. The colour temperature of the screen can be modified if you think it doesn’t match that of your calibrated computer monitor, but the contrast and gamma cannot be altered.

Pentax K-r features:

• - 12.4-megapixel CMOS image sensor  (100-25600 ISO range)
• - 6 FPS framerate that captures 25 images in a single sequence
• - 720p HD video at 25 FPS
• - Shake Reduction mechanism
• - Dust Removal mechanism
• - 3-inch, 921K dot display  (170 degree viewable)
• - In-camera image processing and Special Effects filters
• - 11 point SAFOX IX autofocus system
• - Choice of rechargeable lithium-ion or 4 AA batteries
• - In-camera HDR image capture

“The Pentax K-r doesn’t really do enough for us to recommend it over equivalent Sony, Canon or Nikon models, but it’s a reliable performer with a great kit lens. If you’re already a Pentax DSLR user looking to step up it’s a great choice.”
Rating: ★★★★☆

CameraGearGuide writes:

“In conclusion, the K-r comes highly recommended so long as your focus is largely photographic. Fast, compact, and adept at taking a pretty picture, the Pentax K-r in our opinion would make an excellent first DSLR and certainly would be a well chosen gateway into the compact Pentax system and its library of fun in their own right prime lenses. “

The PENTAX K20D also has the Program Auto, Sensitivity Priority (Sv), Shutter Priority (Tv), Aperture Priority (Av), Shutter and Aperture Priority (TAv) and Manual exposure modes that are the standard features (plus a few unique options) on any DSLR. The K20D also features a Bulb mode (B), which allows you to manually control how long the shutter remains open for extremely long exposures. The X-Sync mode automatically defaults to the standard flash sync speed for the K20D: 1/180 seconds. User mode is a custom mode that the photographer can preset to their favorite shooting mode and settings.

The Image quality of K20D  is also impressive. The switch to CMOS not only gave Pentax the capability to add Live View shooting, it also let them get better control over noise at higher ISOs. Strangely, you’ll still notice a fair amount of speckles at ISO 3,200 and ISO 6,400 on the K20D, but that’s partially because the camera defaults to minimal noise reduction. You can turn that up if you like, but we preferred it low because that let the images retain a large amount of finer detail that becomes blurred away on a lot of other cameras. The sensor-shift Shake Reduction certainly helps to keep images blur-free to an extent, but it could probably be more effective. We were able to get more than one stop of leeway — meaning we could shoot at a shutter speed less than half as fast as we normally would.

The PENTAX K20D incorporates a newly developed image sensor to bring out the optimum performance of PENTAX interchangeable lenses.  Its is a 2.7 inch LCD with 230,000 dots and adjustable brightness levels. The monitor itself is a “wide view” type with a viewing angle of more than 140 degrees both vertically and horizontally. You can easily show images to multiple people using the camera’s monitor, and images can be magnified up to 12x magnification. The monitor also includes a “Live View” mode which allows you to compose shots with the LCD (more on that later).

The K20D has 72 rubber seals in its little body to keep out moisture and dust. For example, if you open the battery compartment door, you’ll notice the small O-ring around the rim of the door. Speaking of batteries, the K20D’s 1620mAh lithium ion rechargeable battery will give you up to 530 shots per charge when using the flash for 50 percent of those shots, though that climbs to 740 shots per charge if you don’t use the flash at all. Of course, that doesn’t compare terribly well with the 40D’s rating of 800 images with 50 percent flash or 1,100 without.

The camera also offers an array of advanced features and user-friendly functions, including: a new Custom Image function that lets the user select or adjust the image’s finishing touches to their preference; an upgraded, more reliable SR (Shake Reduction) system; a comprehensive Dust Removal system; a multi-mode exposure system for faithful reproduction of the photographer’s creative intentions; and a dependable dust-proof, water-resistant body construction. As a result, the K20D easily meets the diversified, exacting demands of discerning photographers.

The K20D development is based on the popular PENTAX K10D, which not only attracted great interest and high acclaim from users around the world, but also swept prestigious camera awards across the globe in 2007. The new CMOS image sensor, exclusively developed for the K20D, has been designed to optimize the performance of PENTAX interchangeable lenses. Featuring approximately 14.6 effective megapixels and the latest noise-reduction technology, it assures superb image quality a step above its predecessors.

“noise isn’t a practical factor until ISO 800, edges are well-preserved, and even at ISO 1,600 8×10-inch prints are excellent. .. When used properly the K20D can produce excellent images, making it easy to declare it a Dave’s Pick.”

The Pentax K7 Digital SLR Camera 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.

With the introduction of the K-7, Pentax appears to be positioning itself as a leader in the rugged camera category, making a smaller camera that is better sealed against the elements, with 77 seals that deliver “weather, dust, and cold resistance.” That latter point is perhaps the most unique, with no other digital SLR of this class offering a promise of durability down to 14 degrees Fahrenheit. 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 Pentax K7 Digital SLR Camera a tremendous photographic tool, perfect for all discerning digital SLR photographers.

“Pentax has announced the K-7 mid-level DSLR, based around an updated version of the Pentax/Samsung 14.6 MP CMOS sensor. The specifications – magnesium alloy body, 5.2 fps shooting, 720p HD video, 920,000 dot LCD – will not come as a surprise to the Pentax faithful, following comprehensive leaking of its details. However, we’ve been lucky enough to get hold of a pre-production camera to bring you a detailed hands-on preview of the K-7.”

whatdigitalcamera.com writes:

“The new model 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.”

photoreview.com.au writes:

“Featuring a solid body with a chassis made from high-rigidity stainless-steel alloy and housing of durable but lightweight magnesium steel alloy, the K-7 has 77 special seals to make it weatherproof, dustproof and cold-resistant.”

TrustedReviews writes:

“Pentax K-7 is a superb camera, and really puts the cat among the pigeons at the top of the APS-C DSLR market. It has rugged weatherproof build quality, superb handling and offers every creative feature you could possibly want and more besides. Performance and image quality are a match for anything else in its class. It’s a tempting package for any keen amateur or semi-pro. “

CrunchGear writes:

“the K-7 is much, much faster at locking on than the K200D and the 50mm f/1.4 that I primarily use with the K200D feels alive. However, I did notice that the K-7 struggled to lock onto multiple subjects even in continuous AF mode and would focus in on something stationary that didn’t seem to be focused on from my point of view.”

ImagingResource writes:

“Small, solid, and sealed, the Pentax K7 makes a superb candidate for the outdoor photographer, occupying the space of a small Rebel, but with the ruggedness to handle both wet and cold weather like a pro. When you make the Pentax K7 your daily shooter, the interface becomes second nature, and you can focus on your photography.”

PhotoReview.au writes:

“Camera response times were occasionally slower than competing DSLRs. Although the review camera powered-up smartly in a little less than one second, the average capture lag of 0.5 seconds is significantly slower than most recent DSLRs we’ve tested. With pre-focusing, this lag reduced to less than 0.1 seconds, which is par for the course.”

“Image quality is great. Comparing the JPEG with the converted RAW of the same image the JPEG is noticeably noisier. The difference between JPEG and RAW files is more marked as you ascend the ISO scale, until you hit ISO 6400, where the JPEG looks smoother than the RAW.”

PhotographyBlog writes:

“The K-7’s image quality is very good. Exposures were generally 1/3rd EV stop under-exposed, perfect for retaining detail in the highlight areas without sacrificing the shadow areas too much, and colours were accurate using the default Bright setting. The HDR mode makes it easy to create images with greatly expanded dynamic range”

ePhotozine writes:

“I’m liking the noise results from the Pentax K-7, not only because they’re among the best I’ve seen from a Pentax model but also because the control that the new processor is commanding over the noise is excellent…..I’m so impressed with the K-7 that I think this is one of the most exciting cameras released this year.”
