Pentax K200D SLR Review
Weather Resistance, Shake Reduction, Dust Removal,
Lens Mount, AF System and Lenses
Seals around the durable K200D body protect the inner components against moisture
and dust particles. The fiber-reinforced polycarbonate body surrounding the high-rigidity, stainless steel chassis
provides plenty of strength for every day use.
Shake ReductionPENTAX's Shake Reduction technology solves one of the oldest photographic problems: blur caused by handheld camera shake. The K Series Digital SLRs produce sharp photos in challenging situations without having to use a tripod. Hand-held photography is now possible with long telephoto lenses or when long exposure times are required due to low lighting levels.
The Shake Reduction (SR) system is integrated into the camera body and is independent of the lens in use.
At the moment of exposure the compensating movement of the image sensor provides
blur-free pictures. The advantage is obvious: you may increase your handheld
shooting by 2.5 to 4 stops.
Over 30 patents have been filed for this SR system, which uses a ball bearing mounted oscillator unit with four electromagnets that hold the free-floating image sensor. Angular velocity sensors detect camera movement and relay the amount of compensation necessary to the electromagnets that move the sensor to compensate for any shake.
10.2-megapixel CCD Image Sensor
The K200D's 23.5 x 15.7 mm CCD image sensor records photos with a resolution of up to 10.2 megapixels. This is enough for you to produce astounding enlargements without difficulty. The high resolution sensor also allows photos to be cropped so that your composition may be perfected. High resolution combines with the DDR2 buffer memory to give quick capture rates up to 2.8 frames per second
PRIME Image Processing
PENTAX created the PRIME (PENTAX Real IMage Engine) system to match
the performance requirements of higher resolution sensors. The PRIME engine converts the digital signal into the
image you desire by assuring truer color tones, a wider dynamic range, and natural looking high ISO images.
PRIME strives to provide results similar to what you see shooting with film.
Dust Removal System
The Dust Removal system on the K200D is a marvel of technology. The surface of the low pass filter
is sealed with a nanotechnology-based fluorine coating so dust has a difficult time adhering
to the sensor surface. Any dust that remains is shaken off when the SR system shifts
the CCD at high speed. The dust that is shaken off the CCD, then falls onto an adhesive sheet eliminating
any possibility of its returning to the CCD surface. Dust spots are now a thing of the past, along with
annoying and time consuming retouch work.
11-Point TTL AF System
PENTAX K-Series cameras feature an 11-point autofocus system. In automatic operation (AUTO) the camera recognizes which object is nearest and chooses that object as the main focus point. For more direct control, select any of the 11 points individually. It is also possible to simply select the center of the image as your main point of focus. With Continuous Autofocus, the focus points adjust as your subject moves within the frame, or should you prefer more direct control, you may always focus manually.
PENTAX Lens Mount
The K200D has an electronically controlled, vertical run, focal plane shutter offering shutter speeds from 1/4000 to 30 second with
a bulb setting available.
PENTAX has manufactured over 24 million lenses in the last six decades so there's probably a lens for any requirement you have. PENTAX dSLR bodies offer backward compatibility with each and every one of these lenses (adapter required for screw mount and 645/67 lenses). Choose from an assortment of new DAH, DA Limited and DA lenses specifically designed for use with PENTAX digital SLRs or grab your favorite glass from your camera bag.
Five new lens models, all developed specifically for PENTAX digital SLR, were released with the K200D. The complete line of lenses currently contains 22 models. Each new lens features a Quick-shift Focus System for instant switching from auto focus to manual and the PENTAX SP coating that protects the exposed lens elements from grease and dust.
The new lenses pricing and shipping dates are:
Each PENTAX DA series lens features a tightly sealed, weather-resistant and dust-resistant construction to enhance durability for use in rainy or dusty conditions - making each a perfect companion for the weather-sealed K200D . The lenses also feature the PENTAX original Quick-Shift Focus System for instant switching to manual focus operation and PENTAX original SP (Super Protect) coating to repel dust, water and grease. A new SDM system has been incorporated for smoother, quieter autofocus operation using a built-in supersonic motor.
Following are more details on some of the new DA-series lenses.
PENTAX DA 200mm f/2.8 ED (IF) SDM
PENTAX DA 300mm f/4 ED (IF) SDM
