• LCD Monitor: 2.7-inch display for Live View, menu navigation, and image playback.
• Control Dials: Adjust settings like aperture, shutter speed, and ISO.

4.2. Exposure Control

The K20D offers versatile exposure modes:

• Program AE (P): Camera sets both aperture and shutter speed automatically.
• Shutter-Priority AE (Tv): You set the shutter speed, camera sets aperture. Ideal for controlling motion blur.
• Aperture-Priority AE (Av): You set the aperture, camera sets shutter speed. Ideal for controlling depth of field.
• Manual (M): You set both aperture and shutter speed.
• Sensitivity-Priority (Sv): You set the ISO, camera sets aperture and shutter speed.
• Shutter/Aperture-Priority (TAv): You set aperture and shutter speed, camera sets ISO.

4.3. Image Quality Settings

Select your preferred image format and quality:

• RAW: Unprocessed sensor data, offering maximum flexibility for post-processing.
• JPEG: Compressed image format, available in various quality levels (e.g., Fine).
• The camera supports simultaneous RAW+JPEG capture.

4.4. Shake Reduction (SR)

The in-body Shake Reduction system minimizes camera shake. It is compatible with all Pentax K-mount lenses, including older manual focus lenses. The system automatically detects camera movement and shifts the image sensor to compensate.

4.5. Live View Function

To activate Live View, press the Live View button (refer to Figure 3). This allows you to compose and focus using the LCD monitor, which is particularly useful for low-angle or high-angle shots. You can also zoom in 4x or 8x for precise focus confirmation.

4.6. Dust Reduction System

The K20D features a multi-faceted dust reduction system:

• Super Protect (SP) Coating: Applied to the image sensor to prevent dust adhesion.
• Sensor Shift: High-speed vibration of the image sensor dislodges dust particles.
• Dust Alert: A unique function that maps the exact location of dust on the sensor, aiding in manual cleaning.

4.7. Autofocus System

The SAFOX VIII autofocus system features 11 sensor points (9 cross-type) for precise focusing. Selectable focus modes include single-shot AF (AF-S) and continuous AF (AF-C).

4.8. Continuous Shooting

Capture fast-moving subjects with continuous shooting at approximately 3 frames per second (fps) for up to 38 JPEG images. A high-speed burst mode is also available at approximately 21 fps (at 1.6 megapixels).

5. Maintenance

5.1. Cleaning the Camera

• Use a soft, lint-free cloth to clean the camera body. For stubborn dirt, slightly dampen the cloth with water.
• For the lens, use a lens brush or blower to remove dust, then a specialized lens cleaning solution and cloth.
• Avoid using organic solvents like alcohol or paint thinner, as they can damage the camera finish.

5.2. Battery Care

• Store batteries in a cool, dry place when not in use.
• Avoid fully discharging the battery regularly to prolong its lifespan.
• Charge the battery using the supplied charger.

5.3. Sensor Cleaning

While the K20D has an excellent dust reduction system, occasional manual sensor cleaning may be necessary. Use the Dust Alert function to identify dust spots. For persistent dust, consult a professional camera service center or use a sensor cleaning kit with extreme care.
