Chapter 3 Adjustments and Settings Zooming Adjusting the Focus The lens supplied with the PMW-320K allows you to shoot with manual and servo zooming. Switching between Zoom Modes Set the ZOOM switch to SERVO (servo zoom) or MANU (manual zoom). Using Manual Zoom With the ZOOM switch set to MANU, turn the zoom ring. Using Servo Zoom With the ZOOM switch set to SERVO, operate the power zoom lever. The current lens zoom position appears in the viewfinder, over the range 0 (wide-angle) to 99 (telephoto) (see page 29). Push to the W (wide) side when you want wideangle, and push to the T (telephoto) side when you want telephoto. The zoom speed increases when you push the lever deeply, and decreases when you push less deeply. The lens supplied with the PMW-320K allows you to adjust the focus in the following three ways. Full MF (full manual focus) mode This mode supports focusing with the focus ring only. Without changing your grip, you can focus all the way from ∞ to the shortest shooting distance. MF (manual focus) mode In this mode, auto focus is enabled temporarily when you press the PUSH AF button. You can also use the MF assist function. AF (auto focus) mode In this mode, auto focus is always enabled. The focus ring and the PUSH AF button are also enabled. Note The lens is designed with an extra margin at the infinity position (∞), to compensate for focus drifting due to variations in temperature. When shooting a subject at infinity in MF or Full MF mode, check the picture in the viewfinder as you focus. Adjusting in Full MF Mode When you slide the focus ring back (toward the camcorder), the focus mode becomes Full MF mode, in which all focus adjustments are manual. Note When you slide the focus ring back, the focus instantly moves to the mark position. Focus by turning the focus ring while viewing the viewfinder. The distance indications on the ring are valid in Full MF mode. The distances where the picture is in focus correspond to absolute positions of the focus ring. Zooming / Adjusting the Focus 57
