Pentax K200D
- Evaluative metering ( 16 zones )
- Spot
- Center-weighted average metering
The Pentax K200D is a digital SLR entry-level, which was presented in January 2008. It has a CCD sensor with an effective resolution of 10.2 million pixels, the maximum image size is 3872 × 2592 pixels. It is the successor of the Pentax K100D and their derivatives, however, has taken over the functions of much higher classification model Pentax K10D.
With the U.S. marketed under the name Pentax K2000 Pentax Km finally came in the summer of 2008, an even lower-priced entry-level model on the European market.
Important features
The K200D has a CCD sensor with a resolution of 10.2 effective megapixels and has the functioning of all the lens image stabilization system Shake Reduction, in which the sensor is mounted movably. The electromagnetic sensor movement can also be used to throw off the sensor may adhering impurities. The K200D is protected by a system of 60 seals against water and dust (as well as the Pentax K10D ).
The exposure parameters can be controlled via a dial ( thumbwheel ) on the right top corner of the camera back. The functions of the wheel are laid down in the respective exposure programs and partially configurable.
As is customary for an entry-level model, the K200D has about scene modes and a scene mode automatic with which the exposure is adjusted to the recording situation. Besides the usual automatic exposure program, aperture - priority auto and she had also introduced the K10D in the program Sv in which the ISO value can be selected using the control dial. In addition, the K200D is equipped with an Auto ISO with selectable peak, the ISO range ranging from 100 to 1600th in the program P, the parameter sharpness, color and contrast for the camera-side JPEG creation can be configured in the admission and pre-defined in several store profiles.
The camera RAW images in either Pentax 's own PEF format or universal developed by Adobe DNG format. For temporary switching to RAW format, the K200D has its own key. As RAW files captured images can be subsequently converted with adjustable parameters into the JPEG format within the camera.
Power is supplied by four standard AA cells ( AA ).
Bayonet and Lenses
The K200D is equipped with the KAF2 bayonet in the version without mechanical aperture simulator. Lenses that have an aperture ring without A- position, can be used only with working aperture. This applies to all lenses that are equipped with the original version of the K- bayonet and were produced from 1977 to about 1984. You can see the camera but just automatically dim when using such lenses by pressing the green button and it can determine the exposure (auto working aperture ). The reason for this approach is the lack of feedback on the set aperture from the lens to the camera body. This mode can be enabled in the adjustment menu. Lenses with so-called power zoom can also be used, although the electric zooming can not be used, because the provided electrical contacts on the bayonet are now used for the ultrasonic motor for autofocus.
In addition lenses with K bayonet M42 lenses can be used in conjunction with adapters. In this case, the shutter mechanism is not operated by the camera.
Focusing
The autofocus has eleven sensors, including nine cross-type sensors, and shows the focus point in the viewfinder at a bright spot; as well as the choice of a specific sensor for focusing is possible. The bayonet has in addition to traditional autofocus drive, so a built- in casing motor, via electrical contacts for the control of SDM lenses with their own ultrasonic motor.
During manual focusing of the center AF sensor is active as an aid, and this is indicated in the viewfinder when reaching the focal point. The focusing screen has no adjustment aids like split image or microprism collar, and alternative focusing screens are not offered by Pentax. However, a replacement is technically possible and there are other vendors selling alternative focusing screens. In addition, the K200D features a Catch- In -Focus as designated " focus trap " that triggers the shutter when an object is detected as sharp.
With the stop-down button can be either a digital preview created, or even before the exposure, the aperture will be closed briefly to get through the viewfinder to preview the depth of field.
Tests and reviews
While many tests the Pentax K200D certified good image quality in raw data format, the quality of JPEG images has been criticized in terms of noise reduction and color simultaneously. However, the user can use the many setting to change the conservative factory settings and adapts to your personal taste.
