Pentax K20D - Dust shield function|
The Pixel mapping function is completed automatically by the camera so that annoying and time-consuming retou-ching can be avoided. An integrated dust shield prevents dust particles from contaminating the sensor. This is a two-step system that consists of an effective dust-rejecting special coating on the low-pass filter and a function that vibrates to shake the remaining dust off the sensor. The vibration system can be set to work automatically when the camera is switched on or can be activated manually as needed. The dust that is shaken off the image sensor falls onto an adhesive sheet positioned at the bottom of the SR unit, eliminating any possibility of its returning to the image sensor surface. As any such physical system is only effective while in actual use an additional warning system has been integrated. With the "Dust Alert" function a vertically and laterally correct image of the sensor is shown on the monitor to indicate exactly where any stubborn dust particles may be adhering to the sensor.
Pentax K20 D - Finer compression levels
Due to demand by photographers and the trade the Pentax K20 D is equipped with finer compression stages. Now 4 JPEG compression levels are available providing for more highly detailed pictures. Most relevant for those in the know, the camera can store files as JPEG or as RAW or, depending upon user preference, simultaneously as both JPEG and RAW. The RAW selection may be either the Pentax "PEF" standard or the Adobe Photoshop "DNG" format. By pressing the RAW button the file format can easily be changed and the sequence individually specified.
Pentax K20D - 3D Sensor image stabilization system
Like the Pentax K10D this new top-of-the-range Pentax model features the in-camera opto-magnetic 3D-Sensor image stabilisation system ("Shake Reduction" system). The clear advantage of this system is that there are no restrictions on the choice of lenses. This unique "Shake Reduction" is fully functional with all Pentax K-mount lenses.
Pentax K20D SLR - AF Adjustment
The Pentax K20D works with a precision 11-point autofocus system with 9 cross sensors (SAFOX VIII) and the AF is freely adjustable. With the "AF Adjustment" function the focal point can be uniquely optimized for each lens, or, when desired, for all lenses around a freely adjustable, correction factor. Front or back focus problems are now a thing of the past. The bright pentaprism viewfinder clearly displays a 95% field of view. The focusing screen is replaceable – additional focusing screens are optionally available.
Pentax K20 D DSLR - 2.7-inch LCD monitor
On the large 2.7” monitor with 230,000 dots the resolution of the image quality can be reliably examined. A 32x magnification factor is provided to supplement more critical evaluation of the image. To provide for a better overview the display on the monitor can be divided for thumbnail image displays. Text size can be increased by 150%. The Preview option permits control of picture composition and exposure settings before the shutter is actually released, thus avoiding unnecessary test shots especially for night and series photographs. The Pentax K20D digital preview offers a marked improvement over the picture preview of the Pentax K10D. Now all photographic parameters can be changed on the basis of the electronic preview and the preview can be stored directly onto the memory card.
Pentax K20D SLR camera - Live View function
One of the most important innovations for SLR cameras is the Live View function, a feature that you know from compact cameras. Shooting conditions for a working photojournalist are not always optimal: they are often in situations where camera placement can be difficult, necessitating shots from extremely high or low angle. This is where the Live View function comes into its own, replacing the viewfinder. Coupled with the 160° viewing angle of the monitor getting the crucial shot has become easier.
Pentax K20D digital SLR - LCD Colour Tuning
Working photographers fully appreciate monitor calibration as the first important step of the digital workflow. This is where the Pentax K20D shows another of its hidden strengths. Not only can the brightness of the monitor be changed but the "LCD Colour Tuning" functions allows the on-screen colour reproduction to be varied through in 49 steps.
Pentax K20D camera - Luminous sensitivity
The luminous sensitivity of the Pentax K 20D operates over an extended range of ISO 100 to ISO 6400. The dynamic range has also been extended by a full stop so you now have an additional 2EV to play with. The result; improved details in bright and shaded areas. Additionally the Pentax K20D offers five colour profiles and a B&W profile that can be individually adapted. The photographer now has the possibility of adapting the colour characteristic of his images to meet his needs and circumstances exactly.
Pentax K 20D - Shake Reduction system
Technologically advanced and particularly fast image processing (PRIME), discriminating functions and features, and the in-body Shake Reduction system make the Pentax K20D a genuine top class camera for ambitious photographers. The new Pentax K20D digital reflex camera is durable, compact and easy to use. It has a dust and splash-proof body and is compatible with all Pentax K-mount lenses.
