Pentax K20K Digital SLR Highlights
Newly Developed CMOS Image Sensor The Pentax K20D features a newly developed CMOS (complementary metal oxide semiconductor) image sensor measuring 23.4 mm x 15.6 mm. In designing the K20D, Pentax made the significant transition to a higher resolution 14.6 megapixel sensor, rivaling the detail previously only found in images captured with 35mm film. This considerable gain offers 50 percent more resolution than 10 megapixel sensors, and 20 percent more resolution than 12 megapixel sensors. Pentax Imaging (a leading innovator in the imaging business) collaborated with Samsung Electronics (a market leader in developing and producing semiconductors) in the development of the 14.6 megapixel CMOS Sensor found in the Pentax K20D Digital SLR. The larger photo diode in the sensor gathers more light in a shorter time and therefore can respond more sensitively. As a result, the K20D is able to achieve higher sensitivity levels (up to 6400 in the expanded ISO mode). Also, there is a more direct light path to the pixels. Coupled with a high-performance imaging engine incorporating Pentax-original image-processing technologies programmed to yield natural, true-to-life images, the new model assures fine-detailed, rich-gradation images.
Pentax Original Shake Reduction mechanism The K20D is equipped with the Pentax-developed Shake Reduction mechanism, which reduces camera shake for sharp, blur-free images even under demanding shooting conditions, such as shooting with a telephoto lens, shooting in low light conditions or at night without supplementary flash illumination, or using extended exposures for sunset scenes. This innovative mechanism offers outstanding compensation equivalent to approximately 2.5 to 4 shutter-speed steps. In addition, the lighter image sensor unit and refined data-control algorithm offer improved image stabilization over previous models. Pentax Shake Reduction is compatible with existing Pentax interchangeable lenses.*
* Lenses compatible with this mechanism are: Pentax K-, KA-, KAF- and KAF2-mount lenses, screw-mount lenses (with an adapter); and 645- and 67-system lenses (with an adapter). Some functions may not be applicable with certain lenses.
Large, 2.7-inch wide-view LCD monitor The K20D features a large 2.7 inch color LCD monitor. The wide-view design allows the photographer to view the monitor image from approximately 160 degrees both vertically and horizontally. Since it assures effortless image viewing from a diagonal position, it facilitates low- and high-angle shooting using the Live View function.
New Live View function The K20D features a Live View function that allows users to view an image on the LCD monitor during shooting. This feature is beneficial when the photographer moves his or her eye from the viewfinder in specialized applications, such as low and high-angle shooting, or when perfecting composition. The function also allows users to confirm the Shake-Reduction effect on the monitor while shooting.
High-performance, high-speed PRIME Imaging Engine The K20D incorporates the Pentax-original PRIME (Pentax Real IMage Engine). Designed exclusively for Pentax digital SLR cameras, the engine ensures well-balanced, true-to-life images with faithful color reproduction by efficiently controlling digital signals transmitted by the CMOS image sensor. It also allows complete control over other photographic factors including white balance and the new Custom Image functions. This imaging engine also features a Double Data Rate 2 (DDR2) memory to assure speedy image processing and high-speed data transfer.
Custom Image function The K20D is equipped with a new Custom Image function that lets the user select one of the six modes and adjust an images processing to their preference by automatically adjusting tone, saturation, contrast, and sharpness. These modes include Natural, Bright, Portrait, Landscape, Vibrant, and B&W image modes. The photographer can make further fine-tuned adjustments to each setting. The effect on each of the primary colors is shown in a radar-type display on the LCD panel. The user can easily see the effect of their adjustments by using the digital preview option.
Expanded Dynamic Range Function The K20D adds a dynamic-range expansion function, which allows the user to expand the dynamic range (or range of gradation reproduction) while retaining the proper contrast to avoid white-washed areas. With an approximately 1EV expansion effect, it assures beautiful, rich-gradation images.
Dust-proof, water-resistant construction The K20D boasts an extremely reliable weather-resistant and dust-proof construction with special seals applied to 72 different parts of the camera body, including the shutter release button and all the switches, levers, dials. This dependable body makes it possible to use the K20D in the rain or dusty locations without worries.
Comprehensive Dust Removal System With Prevention, Removal and Alerting Devices The K20D features the user-friendly Dust Removal system to prevent dust from sticking to the surface of the CMOS image sensor (or low-pass filter). The Pentax-original Super Protect (SP) coating, applied to the image sensor surface through vapor deposition of a fluorine compound, effectively prevents dust from sticking to the surface. In the next step, dust that may remain on the surface will be shaken off when the system shifts the image sensor at high speed. Finally, the dust that is shaken off the image sensor falls onto an adhesive strip positioned at the bottom of the unit, eliminating any possibility of the dust returning to the image sensor surface. This upgraded Dust Reduction system also offers a new Dust Alert function, which shows the user exactly where dust may be sticking to the sensor surface.
The K20D also features a versatile exposure system for faithful reproduction of creative intentions:
Hyper Program Function The K20Ds Hyper Program function allows users to instantly switch to the Shutter-Priority 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.
Hyper Manual Function When shooting in Manual mode, one push of the green button allows the user to instantly set the proper exposure for the subject.
Sensitivity-Priority mode The K20D 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.
Shutter/Aperture-Priority mode Taking full advantage of the unique capability of digital cameras, which permit 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. This mode allows users to experiment with a greater range of photographic expressions with greater ease.
Bright, clear viewfinder Featuring a glass pentaprism, the K20Ds viewfinder offers an approximately 95 percent field of view and an approximately 0.95x magnification for easy viewing of the subject and effortless confirmation of focus and composition. Coupled with the acclaimed Natural-Bright-Matte II focusing screen, it delivers a large, bright subject image.
Continuous shooting at approximately three images per second To trace the movement of an active subject or capture a sequence of the subjects expressions, the K20D offers a continuous shooting mode that allows the photographer to capture as many as 38 images in succession (in JPEG recording format) at a maximum speed of approximately three images (frames) per second. When switched to the new high-speed advance mode, the user may capture up to approximately 115 images at the speed of approximately 21 images per second.*
* The image size is fixed at 1.6 megapixels in the Burst Shooting mode.
High-precision 11-point wide-frame AF The K20Ds sophisticated SAFOX VIII autofocus system features 11 sensor points (with nine cross-type sensors) to automatically focus on the subject with utmost precision, even when it is positioned off center. When the subject is captured in focus, the in-focus sensor point is automatically superimposed in red in the viewfinder for at-a-glance confirmation.
Powerful rechargeable batteries The K20D features large capacity Lithium-ion rechargeable batteries, which can capture approximately 740 images when fully charged. The dramatically improved battery capacity (over the previous K10D) is the result of a new energy saving design.
Additional Features- A PC Sync socket for shooting with studio lights. The camera remains weather and dust sealed even when the PC socket cap is removed.
- Choice of 16-segment multi-pattern metering, center-weighted metering and spot metering to accommodate various photographic applications

I've been a serious Pentax photographer for over 20 years... so naturally, because of my investment in PK type lenses, I purchased one of the first K20D's as soon as it was available.I should have waited!Please understand, there is a reason for all these great reviews. It really is a good camera in many respects. However, if you have special requirements, such as long exposures (e.g. astrophotography), this is NOT the camera to purchase.The K20D uses a new and jointly developed Samsung CMOS imager. Unfortunately, they have not worked out all the kinks... um... namely heat! As a result, the K20D produces a significant amount of noise (hot pixels) and this is why the K20D is the *ONLY* current DSLR camera that forces the user to endure an automatic DFS (Dark Frame Subtraction) for any length of exposure in Bulb mode (or any manual/automatic exposure greater than 15 seconds). This means that a 2 minute exposure is actually 4 minutes, a 30 minute exposure will take 1 hour, and so on...If money is no object, consider Canon or Nikon. Canon is especially prized by astrophotographers as being the best DSLR for long exposures.The other annoying problem is that the K20D is terribly slow (and even worse in low light) with auto focus! Again, Canon and Nikon do a much better job.Other than two major complaints.... I echo the positive attributes spoken by others about this camera.The K20D loses two stars (out of five) because of the forced DFS and high noise levels. Pentax almost made the perfect camera!

I was the unfortunate victim of a thief. My camera bag containing all of my equipment was stolen. I had the new Nikon D90 and loved it. My insurance company reluctantly awarded me a check that covered about a third of the replacement cost for the Nikon gear I lost. I decided that until I had saved enough money to replace the D90 I would buy a less expensive camera to pass the time. Let me start by saying I'm not a pro, but have a few years as an amateur. I spent a week doing research online (thank you dpreview). The result was the Pentax K20D. I purchased it from Amazon for 669, an absolute bargain as it turns out. My wonderful family gifted me with the DA 18-55mm version 2, the 55-300mm telephoto, and the battery grip, all made by Pentax. The build quality is the best I've ever experienced!! Stainless steel frame inside a plastic fiber reinforced exterior shell, more rubber seals than you can imagine, and sealed doors for the memory and battery ( real doors!!). The lenses are as rugged as the body and battery grip, with terrific rubber grips grooved deeply, making a solid and rugged feel that I'm in love with. The Pentax weighs about a third more than the D90 but it feels great and I think it gives me a steadier hand. I think the ergonomics are better than Nikon or Cannon, and It's about the same body size as the D90, I miss the Nikon LCD but I wouldn't go back. The picture quality is just mind blowing, the D90 produced great pictures as well, and I think that this camera equals it in most cases, and exceeds it in others. I've read reviews that claim the K20D shows excessive noise at ISO 1600+, but I rarely ever shoot above 800 so it's not an issue for me. Another issue for reviewers was the frame rate, only 10% of my work is sports or other projects that would necessitate a high frame rate so this camera is fine for me. The K20D produces large image files, a product of a 14.6 mp sensor, and my choice of file type, so it can be slow to save to the memory card. I need to research faster SD cards. I have about 2000 photographs under my belt with this camera and until Pentax updates the K20D I won't be looking for another. The in body shake reduction reduces the cost of lenses and works very well. Live view, and articulating LCD screens are not something I'm interested in so those innovations missing or not done well on this model are not an issue for me. If you want or need either of those buy a point and shoot, this camera is designed for experienced shooters and doesn't have a lot of the automatic or 'green' modes that entry level DSLR cameras have, Pentax makes those cameras but I don't own one. If you are shopping for a camera this is a great piece of equipment and the peripherals made by Pentax are outstanding. I have only one complaint and that is the LCD screen as compared to the Nikon D90, I hope that tops the list for the next incarnation of the K20D.

First, a quick disclaimer - I'm not a pro but probably fall into the serious amateur category after falling in love with my old Minolta Maxxum 7000 over 20 years ago. I'm the person behind the camera at all the parties and occassionally get the exceptional shot worthy of a few "oooh and ahhhs". I've also been holding out on buying anything more than a simple toss around digital until the cost and quality of dslr's were to my liking. As the price and quality of 10+ mp dslr's are now in the comfort range I decided to chuck the point and shoot junk I've been making do with and began shopping in earnest. After testing the Canon the speed seemed nice but I wasn't impressed so I narrowed it down to the Nikon 300 - it seemed to have everything I was searching for in a versatile camera. After adding decent quality lenses, storage, a few extras etc the price was going to come in at roughly $3,500 on sale...not bad but enough to make me take one last look around. On spur of the moment my better half said take a look at Pentax - they have been around forever and are known for making above average lens.So, the K20D pops up with a 14+ mp on sale for $800 or 1/2 the Nikon...so far so good but I was a bit nervous about ordering it despite the good reviews. I spent the better part of the day researching the camera and decided to give it a shot [sorry - bad pun].Ordered the K20D ($800), 8 gb card ($35), battery grip ($120), extra battery pack ($20), remote ($20) tripod ($18 on special), camera strap (free promo) and the Pentax 18-250 mm lense ($350). For $1350 I now have a very versatile camera for almost a 1/3 of the price of the Nikon....suffice to say based on price alone I'm one happy shopper. UPDATE: also added the Tamron 90mm Macro with 1:1 for another $365 after rebate. Good additional lens with a few issues (see my review on it separately). Between the two - have a nice 1:1 macro and portrait lens with a terrific "all around" lens...also added several filters [uv, polarizing, close up] an inexpensive tripod and another inexpensive monopod plus some excellent books...all for less than the cost of the Nikon with one lens!Now, for the performance, look feel etc. The 14+ mp really make a difference - resolution is excellent and compares favorable to film. For the first time I don't feel like I'm missing anything major. This camera takes some beautiful shots even with my own limited testing.The weight and feel are very nice - everything is ergonomically correct at least for my hands, intuitive access on all controls, solid and best of all - sealed! Screen size is adequte and I really appreciate the ability to set colors, font size and other adaptations to fit my needs. Diopter is also adjustable. The lens is reviewed apart but was a great all around choice - responsive and adequate although I intend to purchase additional dedicated/primary lens options soon. One thing I REALLY like about this Pentax is the backward compatibility - Pentax DSLR's allow the use of older Pentax lens so eBay and other options become a great way to find a quality lens at an affordable price. Since my old pricey Minolta lens' are no longer of any use that is a big bonus at least until Sony puts something decent on the market. In the meantime, this was a good starter lense [18-250 mm] that works well with the camera.The menu and pre-sets are easy to use and versatile although I quickly found myself preferring manual - that is just a personal bias however. Preview was easy to use. There are a lot of negative mention regarding the Live screen option...having been playing with slr's for 20+ years I've never used the screen to take photos with but tested it for a few minutes and found it easy enough to use - just not sensitive to take a quality photo. It is possible to zoom in the live preview mode (contrary to what a few have mentioned) but all in all - it's not a feature I use enough to make a valid statement about.The only other "flaw" that makes the camera less than perfect is the 3fps - it is substantially slower than other DSLR's on the market. Since I rarely shoot sports or have need for speed - it isn't a major consideration for me however, I would have gone with the Nikon if it were. This camera is able to shoot rapid series of shots in low quality settings of up to 21 fps - a fun little addition for playing around with but with a quality so low it isn't going to give more than email quality.A few things I REALLY liked about the camera - other than price, resolutoin and intuitive design were several of the upgraded features. In addition to sealing both the camera and battery pack, the ability to take shots in raw and jpeg format at the same time is a great option. Likewise, this is fully compatible with adobe format so saves need for changing formats or fooling around with various options - just set on dual use and go. The battery pack with an extended memory card expand this to a considerable level. I was able to get about 750 pictures off just one battery using a flash part of the time and high resolution settings. The battery pack is very ergonomic, adds a battery back-up that is easy to switch and also allows storage for an additional card and remote control. When fully charged I expect to put at least 1500 photos on the card and battery before changing out - easily.The camera comes with battery and charger, inexpensive camera strap - neigther were mentioned when I was buying so I ordered a battery charger that had to return.One additional note - in addition to 10% off the price of a decent/versatile lens - be sure to register before the end of the year. Pentax is offeringa FREE upgrade to 3 year warranty on this purhcase!!! That beats all others hands-down. In addition to the pentax 18-250 mm lens, I also purchased the Tamron 90 mm macro which has a $90 rebate AND 6 year warranty right now. Good stuff! Good deals - even if Amazon has lowered the price $35 since I bought this a week ago [argh] and offers a free camera case that I missed [double argh]. Still very pleased.Will try to review again after having owned/used but so far REALLY pleased with price, performance and resolution of the camera.UPDATE: I've now owned this for several week and had a couple opportunities to use it in different settings - outdoor shots, inside with a little "mini studio" for portraits, some macro work etc... although the "user" [myself] is rusty and still learning all this camera is capable of doing - the results are consistently great....even when I thought they would be inferior. The range of this camera is pretty amazing especially in low light settings or shadows where other camera's begin to show extreme noise. Side by side comparison to a more expensive Canon model - this took more clear shots hands down...in fact, this can actually allow ISO settings up to 6400 {although not great quality at that level] whereas the Canon can't even attempt it. At more modest levels, this handles photos with ease while the Canon has already started showing serious noise distortion.In fact, the one issue I've run into while taking portraits was "too true to life". This camera shows every detail - much to the dismay of at least one or two aging family members. Of course, that is easy to correct in a good program but if resolution is what you are searching for this one has it!Another great feature is the bracketing. I'm interested in pursuing a bit of High Dynamic Range photography - something new that is made possible by the digital format. I've not had an opportunity to delve into this much yet but the resolution of this camera combined with the bracketing feature make it a LOT easier to get started in this creative endeavor. After purchasing several books on the topic I was a little worried about the complexity - no need. This camera makes it relatively simple to try out this fun and creative new method. While it isn't something I plan to use all the time, it IS a fun and exciting area that expands the entire photography field beyond what was ever possible with film.Finally, for those that appreciate black and white photos - I can report this provides a very nice redition. This was originally another area of concern for me since so many digital pictures seem to have either a yellow or reddish cast rather than true black and white/greyscale. While much will depend upon who you use for printing the pictures, at least you will find a responsive greyscale with this camera. VERY little to No need for modification in Photoshop - nearly all were excellent straight from the camera setting.Cannot say enough good things - combined with the extended 3 year warranty currently offer [and the big price reduction offered by Amazon...argh] this is a no-brainer. Buy it - you will like it!
