Impressive Body Design Designed to be very compact and ergonomically well balanced, the PMW-350 provides a high level of mobility and comfort in various shooting situations. It inherits these qualities from the XDCAM HD 422 camcorders, which are well accepted by broadcasters and post production houses. In addition, it has a low center of gravity, ensuring outstanding stability on the shoulder. The low-profile design provides a wide space between the main frame of the camera and the handle, and an unobstructed view to the right-hand side of the camera operator. The main body weighs only 3.2 kg (7 lb 1 oz), and it is one of the lightest shoulder-mount camcorders with three 2/3-inch full-HD imagers. Three 2/3-inch-type Exmor Full-HD CMOS Sensors The PMW-350 is equipped with three newly developed 2/3-inch-type Exmor CMOS sensors, each with an effective pixel count of 1920 (H) x 1080 (V). These deliver superior picture performance with full-HD resolution. This 2/3-inchtype image sensor allows the camcorder to provide an excellent sensitivity of F12, a remarkable signal-to-noise ratio of 59 dB, and a high horizontal resolution of 1000 TV lines.* In addition, the large 2/3-inch-type image sensors can capture images with a shallower depth of field, giving users more freedom of creative expression. *In HD-SDI, HQ 1080 mode. Lens Package Choice There are two different models of the PMW-350. One is the PMW-350K, which comes equipped with an HD lens with 16x zoom. The other is the PMW-350L, which comes without a lens. Both models have a standard 2/3-inch bayonet lens mount, and the user can choose from a wide variety of optional lenses in the existing 2/3-inch HD lens lineup. Unique Focus Operation - Professional Manual Focus and Auto Focus The supplied lens for the PMW-350K adopts a unique focus ring mechanism, which offers two types of manual focus, plus auto focus operation. The lens is equipped with two independent focus wheel mechanisms, which can be switched by sliding the focus ring forward and back. When the focus ring is in the forward position, the lens works in the same way as a typical auto focus lens. The operator can select either Manual or Auto Focus mode using the AF/MF switch on the lens. When the focus ring is in the back position, the lens has an absolute focus position, which is a familiar feature to professional users. Focus Zoom Iris Low Power Consumption There is no fan motor to ventilate the inside of the body, and power consumption is only 15W*. *Camcorder body only, in recording mode. Front : AF/MF AF/MF Mode • Full AF • One-push AF • MF • AF/MF Assist Back : Full MF Full MF Mode • Full MF (absolute focus position) AF Assist The AF (Auto Focus) Assist function of the PMW-350K enables operators to manually change focus positions using the focus ring in AF mode. This means that AF reference focus positions can be shifted manually to a new position. 6
