It is recommended that the portable communications devices near this unit be powered off.

About the LCD panels

The LCD panels are manufactured with extremely high-precision technology that yields effective pixel rates of 99.99% or higher. However, very rarely, one or more

pixels may be permanently dark or permanently lit in white, red, blue, or green.

This phenomenon is not a malfunction. Such pixels have no effect on the recorded data, and the unit may be used with confidence even if they are present.

Phenomena specific to CMOS image sensors

The following phenomena that may appear in images are specific to CMOS (Complementary Metal Oxide Semiconductor) image sensors. They do not indicate malfunctions.

White flecks

Although the CMOS image sensors are produced with high-precision technologies, fine white flecks may be generated on the screen in rare cases, caused by cosmic rays, etc.

This is related to the principle of CMOS image sensors and is not a malfunction.

The white flecks especially tend to be seen in the following cases:

•when operating at a high environmental temperature

•when you have raised the master gain (sensitivity)

•when operating in Slow-Shutter mode

Aliasing

When fine patterns, stripes, or lines are shot, they may appear jagged or flicker.

Flicker

If recording is made under lighting produced by discharge tubes, such as fluorescent, sodium, or mercury-vapor lamps, the screen may flicker, colors may vary, or horizontal stripes may appear distorted.

In such cases, set the Flicker-Reduction function to Auto mode (see page 68).

In some cases, such phenomena may not be improved with the Flicker-Reduction function. It is recommend to set the electronic shutter speed

to 1/100 sec. in 50-Hz areas and to 1/60 in 60-Hz areas.

Focal plane

Owing to the characteristics of the pickup elements (CMOS sensors) for reading video signals, subjects that quickly move across the screen may appear slightly skewed.

The luminance at the top and bottom of the screen may change when shooting a flashlight or a light source that quickly flashes.

Note on the viewfinder display

Picture on the LCD screen in the viewfinder may be distorted by the following operations:

•Changing the video format

•Rec Review

•Starting playback from the Thumbnail screen

•Reversing the viewfinder

PMW-EX3 specifications

The Sony PMW-EX3 is a professional camcorder that has established itself as a favorite among filmmakers, broadcasters, and content creators. Launched as part of Sony's XDCAM EX series, the PMW-EX3 is renowned for its versatility, robust features, and high-quality output.

One of the PMW-EX3's standout features is its ability to record in high-definition using the MPEG-2 compression codec, allowing for 1080p, 1080i, and 720p recording options. This flexibility makes it suitable for a wide range of applications, from documentary filmmaking to commercial shoots. The camcorder supports various frame rates, including 24p, 30p, and 60p, enabling users to achieve a cinematic look or high-speed motion recording depending on project requirements.

The EX3 utilizes a 1/2-inch Exmor CMOS sensor that excels in low-light conditions, delivering stunning image quality with rich detail and dynamic range. This sensor contributes to the camera's ability to produce vivid colors and natural skin tones, which is essential for professionals seeking to create visually compelling content.

Another notable feature is the interchangeable lens system. The PMW-EX3 comes equipped with a 14x Fujinon zoom lens, but users have the option to use a variety of lenses thanks to its compatibility with Sony's PL-mount. This adaptability allows for creative freedom when it comes to framing shots and achieving various visual styles.

The camcorder's extensive connectivity options enhance its functionality. It includes HDMI, SDI, and composite outputs, giving users the flexibility to connect to external monitors, recorders, or switchers during live productions. The EX3 also features two SxS memory card slots for simultaneous recording and relay recording, ensuring that users have a reliable workflow without interruptions.

For audio capture, the PMW-EX3 is equipped with two XLR inputs that support professional-grade microphones. This feature is crucial for filmmakers and broadcasters who require high-quality sound to complement their visuals.

The ergonomic design of the PMW-EX3, coupled with its lightweight build, makes it easy to handle for extended shooting periods. The user-friendly controls and customizable settings allow operators to quickly adapt to changing shooting environments, ensuring they never miss a shot.

In conclusion, the Sony PMW-EX3 combines high-definition recording capabilities, versatile lens options, and professional audio features in a compact and user-friendly package. Its reliability and exceptional image quality make it a valuable tool for anyone serious about video production.
