Setup
Before using your camera, perform the following setup steps:
- Charge the Battery: Insert the supplied NP-FW50 Lithium-Ion battery into the charger and connect the charger to a power outlet. The charging indicator will illuminate and turn off when charging is complete.
- Insert Battery: Open the battery cover on the bottom of the camera and insert the charged battery, ensuring correct orientation. Close the cover securely.
- Insert Memory Card: Open the memory card slot cover. Insert a compatible SD/SDHC/SDXC or Memory Stick Pro Duo/Pro-HG Duo card with the contacts facing the correct direction until it clicks into place. Close the cover.
- Attach the Lens: Align the white index mark on the lens with the white index mark on the camera body. Mount the lens by rotating it clockwise until it locks into position.
- Initial Settings: Turn on the camera using the power switch. Follow the on-screen prompts to set the language, date, time, and time zone.
Operating the Camera
The Sony Alpha NEX-3 offers various modes and features for capturing images and videos.
Basic Photography
- iAuto Mode: For automatic scene recognition and optimal settings, rotate the control wheel to select the 'iAuto' mode. The camera will automatically adjust exposure, white balance, and other parameters.
- Taking a Picture: Frame your subject using the 3-inch tilting LCD. Press the shutter button halfway down to focus, then press it fully to capture the image.
Advanced Shooting Modes
For more creative control, the NEX-3 provides Program Auto (P), Shutter Priority (S), Aperture Priority (A), and Manual (M) modes. Access these via the menu system using the control wheel and soft keys.
- Sweep Panorama: This mode allows you to capture wide panoramic images by sweeping the camera horizontally or vertically. The camera automatically stitches multiple images together.
- Hand-held Twilight Mode: Captures six images at high speed and combines them to reduce noise in low-light conditions without a tripod.
- Anti Motion Blur Mode: Similar to Hand-held Twilight, this mode combines six shots to reduce blur caused by camera shake or subject movement in low light.
Video Recording
The NEX-3 can record high-definition video in MP4 format (720p/30p or 480p/30p).
- Start/Stop Recording: Press the dedicated MOVIE button to begin or end video recording.
- Focus and Exposure: The camera automatically adjusts focus and exposure during video recording with E-mount lenses. Exposure compensation can be adjusted using the control wheel.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your camera.
- Cleaning the Camera Body: Use a soft, dry cloth to wipe the camera body. For stubborn dirt, slightly dampen the cloth with water. Avoid using organic solvents.
- Cleaning the Lens: Use a lens blower to remove dust. For smudges, use a lens cleaning solution and a soft lens cloth, wiping gently in a circular motion from the center outwards.
- Sensor Cleaning: If dust spots appear on images, the image sensor may need cleaning. This is a delicate procedure; it is recommended to have this performed by a qualified service technician.
- Battery Care: Store batteries in a cool, dry place. Do not expose them to extreme temperatures. If not using the camera for an extended period, remove the battery.
- Storage: Store the camera in a dry, well-ventilated area, away from direct sunlight and extreme temperatures. Use a desiccant if storing in humid environments.
