68Recording in Aperture-Priority (Av) ModeThe aperture value can be adjusted in 1/16 EV stops; however, the aperture value displayed on thescreen will change only in 1/4 EV stops.Available aperture values (with the HD 20x L IS II or HD 20x L IS III lens)F1.6, F1.8, F2.0, F2.2, F2.4, F2.6, F2.8, F3.2, F3.4, F3.7, F4.0, F4.4, F4.8, F5.2, F5.6, F6.2, F6.7, F7.3, F8.0,F8.7, F9.5, F10*, F11*, F12*, F14*, F15*, F16*, F17*, F19*, F21*, F22*, CLOSE** Can only be selected if the custom function [IRIS LIMIT] is set to [OFF].1. Set the dial to Av.2. Select the aperture using the IRIS dial orthe iris ring (only lenses with manual irisring, like the HD 20x L IS III lens).With the custom function [RINGS DIRECTION]( 104) you can change the direction of theadjustment when you turn the iris ring and IRIS dial(the setting is common to both). Settings other than the aperture value (shutter speed, etc.) are adjusted automatically. Using exposure lock to adjust the exposure manually will change the aperture, overriding the valueselected in Av mode. When the GAIN dial is set to A (automatic gain), the numeric value on the screen flashes when theselected aperture is not appropriate for the recording condition. In such case, readjust theaperture. When the built-in ND filter is activated, the picture may become dark when you set a high aperturevalue. In such case, turn off the ND Filter first and readjust the aperture. With the custom function [IRIS LIMIT] ( 104) you can activate the iris limit to prevent theaperture from closing below the diffraction limit of the lens. If the iris limit is not activated, aperturevalues that exceed the diffraction limit will appear in gray when selecting the aperture. Usingaperture values displayed in gray will cause diffraction blur. When a lens without iris control function is used, the aperture value will not appear on the screen. With the custom function [LANC AE SHIFT] ( 104), you can change the function of the AE SHIFTdial on the optional ZR-2000 Zoom Remote Controller and use it to change the aperture value.IRIS ringCOPY
