<strong>Manual</strong> focus mode<br />
The <strong>Manual</strong> focus mode is set by the front control wheel on the grip in the following manner:<br />
In camera active mode:<br />
1) Press the AF button on the grip.<br />
2) Turn the front control wheel to: <strong>Manual</strong><br />
3) Press Save to store the setting.<br />
You can also use the shutter release button ‘half-press’ function to save a new setting and automatically<br />
return to the main screen.<br />
Natural friction is inherent in the design to purposely reproduce the secure feel of a completely<br />
manual lens.<br />
Please note that when focusing manually, the infinity and closest distance marks on the<br />
lens scale can appear to be positioned beyond the central index. This is only an apparent<br />
effect and does not change the focusing range of the lens.<br />

See Autofocus section for a description of how to use the advantages of a rapid autofocus<br />
check while remaining in <strong>Manual</strong> mode.<br />
Autofocus<br />
Autofocus mode can be either Single Shot or Continuous and is activated by pressing the shutter<br />
release to the half-press position. Its operative range from EV1 - 19 at ISO100. The point of focus<br />
is determined by the area within the central rectangular zone on the focusing screen. When light<br />
levels are too low or the contrast of the subject is too low, auxiliary illumination (situated on the<br />
top of the grip) is automatically activated if desired. The operative distance is approximately six<br />
metres from the camera. Alternatively, a suitable attached flash unit that has a similar facility ( a<br />
Metz 54/70, for example) can also be used instead. This feature can be altered in settings; see under<br />
Custom options/AF assist light.<br />
The autofocus range on the HC 4/120 Macro lens can be limited by a specific setting on<br />
the camera allowing for near range, far range or full range. This only appears on the<br />
grip LCD together with this particular lens.<br />
Single Shot<br />
At Single Shot setting (AF S), the shutter release will be blocked until the camera finds<br />
the optimum focus setting. This ensures that no exposures can be made that are not<br />
finely focused. However, this delay will normally be only a fraction of a second in good<br />
lighting conditions with a clear focusing pattern.<br />
Note though that in this mode the lens will focus at a distance and will remain focused<br />
at that distance while pressure remains on the shutter release button. In this way, you<br />
can focus on a nearby object for example, temporarily positioned within the focusing<br />
zone on the viewing screen and then without releasing pressure on the shutter release<br />
button, recompose knowing that the focus remains on the object chosen even though<br />
it is now outside the focusing zone. Releasing the pressure on the shutter release button<br />
and pressing again half way would now change the focus setting to the distance of the<br />
object within the focusing zone.<br />
See under ‘<strong>Manual</strong> override in autofocus mode’ for a useful way of working with manual<br />
and autofocus settings in a combined manner.<br />
