Pentax PENTAX K20D DIGITAL SLR CAMERA INTERCHANGEABLE LENSES | | |  |
A newly developed CMOS image sensor with 14.6 effective megapixels assures breathtaking, super-high-resolution images
Resolution is a very important factor in deciding the truthfulness of captured images. True-to-life images are the ones that let you sharply and vividly relive the excitement and atmosphere of memorable moments.
The PENTAX K20D comes equipped with a newly developed CMOS image sensor with an astonishing 14.6 effective megapixels. Assuring the fine image quality, it records the world right in front of you with impeccable accuracy and clarity. Its super-high resolution also gives you a definite advantage when cropping captured images or making them into large-size prints. Developed from PENTAX’s unceasing pursuit of higher image quality, the K20D is a state-of-art digital SLR camera providing totally new photographic experiences in digital photography.
Advanced CMOS image-sensor technology harmonizes 14.6-megapixel power with high sensitivity and high image quality
It has been commonly thought that an image sensor with a higher number of pixels improves resolution, while this higher number results in a smaller pixel size and eventually causes a deterioration in image quality. PENTAX found an effective solution to this problem, with the development of a new CMOS image sensor. Although it features approximately 14.6 effective megapixels, it assures high sensitivity and excellent image quality, giving the K20D the outstanding descriptive power to capture and reproduce even extremely subtle differences in light and shade.
Technology that faithfully reproduces the quality of light
In addition to a set of photo diodes, the CMOS image sensor is packed with a number of circuits and components, including transistors and wires. That’s why the light-sensitive area of each photo diode (or pixel) has been limited in conventional CMOS image sensors. With the K20D’s new CMOS image sensor, the latest semiconductor technologies were applied to minimize the space taken up by wires and circuits. In doing this, it succeeded in retaining a large light-sensitive area despite a reduction in pixel size. As a result, the CMOS image sensor balances the two conflicting factors — 14.6-megapixel descriptive power and image quality — at the highest level. This lets you faithfully express even the most delicate light in your images.
