97If the finger is released without the shutter beingdepressed, the exposure meter remains switchedon for approx. 14s and the corresponding LED(s)remain on. When the shutter is activated, the meter switches off and the LEDs in the viewfindergo out.If the main switch is not turned on (i.e. the camerais turned off) and/or the shutter is not cockedand/or the shutter speed dial is set to " B ”, the exposure meter is turned off.Notes: If the shutter is not cocked or the displayshave gone out, the camera is in "Standby " mode.At very low levels of luminance, i.e. at the thresh-hold of the light metering range, the LEDs may take approx. 0.2s to appear.If it is not possible in the aperture priority mode tocreate the correct exposure with the availableshutter speeds, the shutter speed display flashesas a warning (for more details see the section "Theaperture priority automatic exposure mode” onthe right).If manual setting at very low luminance goes be-low the measuring range of the exposure meter,the left-hand triangular LED flashes as a warning.For the aperture priority mode, the shutter speedcontinues to be shown. If the necessary shutterspeed falls below the slowest possible speed of32s, this display also flashes.The exposure modesThe LEICA M7 offers photographers two exposuremodes: aperture priority mode or manual setting.Depending on the subject, the situation and indi-vidual preferences, you can choose between thesomewhat faster and more convenient aperturepriority mode or the fixed setting of the shutterspeed and aperture familiar from other Leica Mmodels.The aperture priority automatic exposure modeWith the shutter speed dial (11) set to the " AUTO ”position, which engages particularly firmly, the camera electronics automatically generate theappropriate shutter speed continuously in the range from 1/1000s to 32s, depending on thefilm speed, either read via DX code or set manual-ly, the measured brightness and the manually selected aperture.As a result the aperture priority mode is particu-larly well suited for shots for which you prefer tomake less settings and where the depth of fieldhas to be set according to composition needs. Theautomatically generated shutter speed can, if necessary, be changed by adjustment of the aperture, e.g. to create certain "wiping effects”with slower shutter speeds or to "freeze” move-ments with faster shutter speeds.
