Chapter 5 Preparation 2 Set the image. (1) Shoot a solid white sheet of paper. (2) Set the lens iris to manual and adjust the iris so that a zebra pattern fills the entire viewfinder screen. • When the piece of paper is unevenly lit, the zebra pattern will not cover the entire screen. Adjust as required. • Make sure that the white paper is not exposed to multiple light sources (example, fluorescent lighting or halogen lamps) of different color temperatures. CHECK LUMINANCE LEVEL ZEBRA ON VF SHADING: USER1 SET OK? YES NO PUSH SET  NOTE • Adjust the white shading in sunlight, under halogen lamp light or other light source that does not flicker. Fluorescent light and mercury lamps tend to flicker and should not be used for this adjustment. • Adjust the light source if the lens iris is out of the range between F4 and F11. • Make sure the electronic shutter is set to off. 3 Adjust white and black balance. (1) Set the WHITE BAL switch to A or B and use the AUTO W/B BAL switch to make an automatic white balance adjustment. (2) Use the AUTO W/B BAL switch to make an automatic black balance adjustment. (3) Again, use the AUTO W/B BAL switch to make an automatic white balance adjustment. 6 If the lens is provided with an extender, turn on the extender function and perform steps 2 to 5 again. • The white shading adjustment need not be readjusted when the extender is later turned off. Setting Chromatic Aberration Compensation (CAC) The CAC function of the camera corrects the registration error caused by the slight chromatic aberration that the lens cannot compensate for. This minimizes color bleeding into the surrounding image areas. Lenses compatible with the CAC function whose CAC data is registered in the camera will automatically start CAC operation. CAC data for the following lenses have been stored in the camera as default values. Camera indication Model numbers of compatible lenses XT17X4.5BRM-K14 XT17x4.5BRM-K14  NOTE • One of the lens model number appearing in the menu represents the lens group. • The CAC function in this camera operates in horizontal direction only. • The CAC function does not operate at +24 dB. • The CAC function may not operate normally in macro shooting. • After the release of this camera, visit our Web site at the address given below for details on new lenses compatible with this function and any changes in this function. https://eww.pavc.panasonic.co.jp/pro-av/ Checking CAC Operating Status When the menu is not open, the CAC indication at the top right of the screen indicates that the CAC function is on. 4 Repeat the operation in step 2-(2). 5 Adjust white shading. (1) Use the JOG dial button to select YES and press the JOG dial button. (2) The message "SHADING ACTIVE" appears on the screen during adjustment. (3) When the adjustment ends after a few seconds, the message "SHADING OK" appears. • When an error message such as "SHADING NG LEVEL OVER" or "SHADING NG LOW LIGHT" appears, adjust the iris. • The adjusted value is automatically stored in memory (USER1, USER2, USER3). 92
