This ensures that no exposures can be made that are notfinely focused. However, this delay will normally be only a fraction of a second in goodlighting conditions with a clear focusing pattern.Note though that in this mode the lens will focus at a distance and will remain focusedat that distance while pressure remains on the shutter release button. In this way, youcan focus on a nearby object for example, temporarily positioned within the focusingzone on the viewing screen and then without releasing pressure on the shutter releasebutton, recompose knowing that the focus remains on the object chosen even thoughit is now outside the focusing zone. Releasing the pressure on the shutter release buttonand pressing again half way would now change the focus setting to the distance of theobject within the focusing zone.See under ‘Manual override in autofocus mode’ for a useful way of working with manualand autofocus settings in a combined manner. The autofocus range on the HC 4/120 Macro lens can be limited by a specific setting onthe camera allowing for near range, far range or full range. This only appears on the gripLCD together with this particular lens.AutofocusAutofocus mode can be either Single Shot or Continuous and is activated by pressing the shut-ter release to the half-press position. Its operative range from EV1 - 19 at ISO100. The point of focusis determined by the area within the central rectangular zone on the focusing screen. When lightlevels are too low or the contrast of the subject is too low, auxiliary illumination (situated on thetop of the grip) is automatically activated if desired. The operative distance is approximately sixmetres from the camera. Alternatively, a suitable attached flash unit that has a similar facility ( aMetz 54/70, for example) can also be used instead. This feature can be altered in settings; see underCustom options/AF assist light.Autofocus override in Manual modeSee Autofocus section for a description of how to use the advantages of a rapid autofocuscheck while remaining in Manual mode.Natural friction is inherent in the design to purposely reproduce the secure feel of acompletely manual lens.Please note that when focusing manually, the infinity and closest distance marks on thelens scale can appear to be positioned beyond the central index. This is only an apparenteffect and does not change the focusing range of the lens.Manual focus modeThe Manual focus mode is set by the front control wheel on the grip in the following manner:In camera active mode:1) Press the AF button on the grip.2) Turn the front control wheel to: Manual3) Press Save to store the setting. You can also use the shutter release button ‘half-press’ function to save a new setting andautomatically return to the main screen.
