The Pentax K200D is a compact
digital SLR. That makes it easier to wield than full-sized DSLRs, like
the Canon EOS 40D and Olympus E-3, but at 5.26 x 3.74 x 2.91 inches and
2.87 pounds with batteries and lens, it isn't going to fit in a pocket
or purse either.
The 10.2 megapixel mirrorshooter has an APS-C sized sensor. At 23.5 x
15.7 millimeters it's slightly smaller than a 35mm frame of film, which
is 36 x 24mm.
Accompanying the sensor is a revamped PRIME image processor. Previous
Pentax image crunchers were criticized as being slow and creating noisy
pictures. This new PRIME version ably addresses those problems.
If you're constantly turning your camera off and on to conserve power,
you'll appreciate this model's rapid startup time. It's almost instantaneous
at around 0.7 second.
In addition to supporting two RAW formats, the K200D captures images
in three sizes and at three quality levels. Sizes are 3872 x 2592, 3008
x 2000 and 1824 x 1216. Qualities are Best, with compression ratios ranging
from 2.3:1 to 5.3:1; Better, with ratios from 4.1:1 to 4.9:1; and Good,
which spans 7.4:1 to 11.2:1. RAW photos can be captured in Pentax's PEF
format or Adobe's DNG file type. (See Compression Table)

Images can be stored on either
an SD or SDHC card. A 1GB card can hold about 58 RAW images, 202-586 images
at Best quality, 35-974 at Better quality and 902-2627 at Good quality.
The unit has a 2.5-inch LCD with a resolution of 230,000 dots. The display
is bright and sharp. Although the monitor can't be used to capture images
directly, it can be deployed to preview shots. That's done by rotating
the camera's power dial clockwise after framing and focusing a shot in
the unit's viewfinder. The potential shot then appears on the LCD. If
you like it, you can save it by pressing the unit's function button and
choosing "save as" from a menu that appears on the display.
If not, you can choose "cancel" from the menu and redo the shot.
Preview can also be used to assess white balance
effects on a shot. To do that, you frame and focus your shot in the viewfinder
and perform a preview capture. Then you enter White Balance mode by pressing
the Fn key and the 9'oclock button on the navigation dial. On the camera's
LCD the preview shot will appear with the White Balance menu superimposed
over it. As you move through the menu choices, their effect on the photo
will be displayed. When you find the effect you want, you choose it, recompose
the picture and shoot it again. If the procedure sounds awkward, it is,
but it beats the alternative--a series of shots using trial and error to
find the best white balance.
In addition to Auto White Balance (AWB), the unit supports settings for
daylight, shade, cloudy, fluorescent light, tungsten lighting, flash pictures
and manual calibration.
The white balance setting can also be fine tuned from the Custom menu.
Two options are available. Colors between green and magenta and between
blue and amber can be modified.
There are also options for determining the
color space used by the camera. Choices are sRGB, which is good for viewing
images on a PC, and AdobeRGB, which is used when pictures will be used with
other devices such as printers. To make it easy to identify the color space
in which images are captured, sRGB photos have file names that begin with
IMG and AdobeRGB image files start with _IGP.
If you'd rather use the preview function to determine the depth of field
of a shot in the viewfinder, you can reprogram the mode to do that through
a menu option.
The LCD can be used as an alternative to
the monochrome display to see data about a shot. When the INFO button is
poked, this information appears on the display.

When capture data is displayed on the screen,
an explanation of the shooting mode can be accessed by pressing the down
arrow on the navigation dial.
Capture information is also available when looking through the viewfinder.
Here is the data displayed in the viewfinder.
Depending on the camera's settings, various
items in the viewfinder can be adjusted with the e-dial located to the left
the viewfinder. When an item can be adjusted by the e-dial, it is underscored
in the viewfinder display.
While the viewfinder display is packed with information, one item we
found wanting was an indicator of the camera's drive status.
Light sensitivity settings supported by the K200D range from ISO 100-1600.
In Auto sensitivity mode, the range, by default, is ISO 100 to 400. The
upper limit of the Auto range, however, can be modified manually.
In addition, there's a Sensitivity Priority mode (Sv). In it, ISO values
can be changed using the e-dial. As those values change, the camera will
automatically choose an appropriate aperture value and shutter speed to
accommodate them.
The dynamic range in shots can be expanded from within the sensitivity
menu, too. When that feature is turned on, the light level readings from
the pixels in the unit's CCD sensor are expanded to make it more difficult
for bright areas to occur in the image.
The native lenses for the K200D are Pentax's DA series. However, it will also
accept D FA and FA J glass, as well as any other lens with an Aperture
A (auto) position.
Two DA lenses were included with our review unit--an 18-55mm F/.5-5.6
lens and a 55-300mm F/4.5-5.8 one. Both have KAF2 mounts with supersonic
motor support. With that support, the lenses were very quiet when focusing
on subjects.
Both lenses also support a Quick-Shift focusing system. It allows for
manual fine tuning of a shot after autofocus is achieved. Although we
found the autofocusing system consistently delivered sharp images, from
time to time, the ability to tweak an autofocus setting was a worthwhile
asset.
Autofocusing by the K200D is performed with
a system based on TTL Phase Matching. There are three focusing modes--one
for single shots (AF.S), one for continuous shooting (AF.C) and manual.
In autofocus mode, the camera will focus on a subject when the shutter
button is partially depressed.
In single shot mode, the unit locks on to subject and remains focused
on that subject until the shutter button is fully depressed. That allows
you to change the framing of a shot while keeping your initial subject
in focus.
Although that technique will lock the focus in a shot, it does not lock
the exposure setting. However, you can program the camera to lock exposure
when you lock focus through a menu choice.
In continuous focus mode, the camera will dynamically focus on a subject
as it moves.
While you can't fully depress the shutter button in single shot mode
if a shot is out of focus, you can do so in continuous mode. As an alternative
to partially depressing the shutter button to focus on a subject, the
OK button in the navigation dial can be programmed to perform that function.
When lighting conditions are challenging, the
bytecam, in single shot mode, will discharge its built-in flash to assist
the autofocus system in obtaining the proper focus for a shot.
What area in the viewfinder is used by the camera to obtain a shot's
focus can also be programmed.
In auto mode, the snapper will select an optimum point--even if it's
not at the center of the frame.
In select mode, you can choose from an 11-point
area which AF point you want the camera to use.
And in center mode, the focusing area is set at the center of the viewfinder.
Only this mode is available to lenses other than DA, D FA, FA J, FA and
F lenses.
Before autofocusing systems became popular, a common technique used by
lensslingers was to predict the path of a moving subject, focus on a point
on that path before the subject got there and fire the shutter when the
subject arrived at the point. Pentax has automated that technique in something
it calls "Catch-in Focus" mode. It works like this.
After activating Catch-in focus mode, you slip
the camera into single shot auto focus mode and focus on a point in the
subject's path. Then you fully depress the shutter button. When the subject
enters the frame, the camera will fire the shutter.
The K200D has eight shooting modes.
There's a Program mode, where the camera chooses the best aperture and
shutter speed for a shot; Aperture Priority, where an F-number is chosen
manually and a shutter value chosen automatically; Shutter Priority, where
a shutter setting is chosen manually and an F-number automatically; the
aforementioned Sensitivity mode; and manual mode, where both aperture
and shutter settings can be altered by hand.
Prolonged exposures can be taken in Bulb mode, where the shutter will
remain open as long as the shutter button is depressed.
Additionally, there are seven picture and eight scene modes.
Six picture modes--Portrait, Landscape, Macro, Moving Object, Flash Off
and Night Portrait--can be accessed from the Mode dial. If that dial is
set to Auto Pic, the camera will automatically analyze a shot and choose
the best picture mode from Portrait, Landscape, Macro and Moving Object
to accommodate it.
By turning the Mode dial to SCN, you can enter the camera's Scene mode.
That mode, usually targeted at novice photographers, automatically chooses
a group of settings for a particular photographic situation. For the K200D
those situations are Night, Surf and Snow, Food, Sunset, Kids, Pet, Candlelight
and Museum. When in Scene mode, scene settings can be accessed by pressing
the Fn key, tapping OK and choosing a setting from the options on the
LCD.
Three common automatic exposure metering modes are supported by the bytecam:
multi-segment, center-weighted and spot metering.
In Multi-Segment mode, the camera divides the frame into 16 areas, meters
each and calculates an exposure based on that information.
In Center mode, the entire frame is metered but the final exposure is
weighted toward the reading at the center of the frame.
And in Spot mode, only the meter reading at
the center of the frame is used for the exposure.
The automatic exposure for a shot can be modified through exposure compensation.
You do that by holding down a button located behind the shutter release
and turning the e-dial with your thumb. Any process involving holding
down one control, working with another and looking through the viewfinder
is awkward at best, and this process is no exception.
Bracketing exposures, on the other hand, was
much easier. You press the Fn button, poke the navigation dial at 12 o'clock
and select the bracket option from the LCD. The bracketing range can be
customized in 1/2 or 1/3 EV steps from the Custom Setting menu.
In addition to Bracketing mode, the mirrorshooter has four other sequential
shooting modes.
There's a single shot mode where an image is captured each time the shutter
button is fully depressed.
There's a continous shooting mode where
the camera will snap a series of pictures as long as the shutter button
is depressed. In Lo continuous shooting mode, the unit will capture up
to four JPEG images at highest quality at 2.8 frames per second. In Hi
mode, the camera will shoot highest quality JPEG images at 1.1 fps until
its memory card is full.
The digcam also has a self-timer with two delay periods: two seconds
and one second.
And an optional remote control (about $20) is
also supported by the unit. The remote can fire the shutter immediately
or after a three second delay.
Shutter speeds for the K200D span 1/4000 to 30 seconds. Exposures longer
than 30 seconds can be performed in the aforementioned Bulb mode.
While most cameras in this category opt for
a proprietary rechargeable lithium ion battery for their power requirements,
Pentax chose to run the K200D off four AAs. I used a quartet of Energizer
Lithium non-rechargeables and their performance was amazing. They lasted
for the entire review period for which I had the camera--more than 30 days.
I took more than 700 shots and had plenty of power left as I packed up the
unit for return to the manufacturer.
The camera has a built-in, pop-up flash, but will also support an external
flash unit. There are five flash modes.
· Auto. The camera automatically determines
if the flash is needed and will pop it up automatically.
· Flash on. The flash is activated by pressing a button. It will
fire when the shot is taken.
· Auto plus red-eye. The flash pops up and reduces red-eye automatically.
· Flash on plus red-eye. When the flash is activated manually, red-eye
reduction is activated automatically.
· Wireless. This allows the camera to be synchronized with an external
flash without a sync cord.
Just as you can alter the exposure of a shot with exposure compensation,
you can control the output of the internal flash with flash compensation.
Compensation values can be set in 1/2 EV or 1/3 EV increments and range
from minus two stops to plus one stop.
In Shutter Priority and Aperture Priority modes, the flash will compensate
for the values you choose. For example, in Shutter Priority mode any speed
1/180 second or slower can be used for a flash photograph and the camera
will automatically choose an appropriate aperture. In Aperture Priority,
the unit will choose a shutter speed of 1/180 or less to accommodate an
aperture choice.
Slow-sync pictures can also be taken with
the flash. That allows both a foreground subject and a bright background--a
sunset, for example--to both be properly exposed.
Standards supported by the K200D include USB 2.0, NTSC/PAL and PictBridge.
