clockwise into place aer ensuring the index on the lens shade aligns with the index on the
front of the lens. When mounted in reverse, they are attached by matching the indexes and
turning counter-clockwise.
Shutter and aperture control
Both the shutter and aperture are electronically controlled and are adjusted by the control wheels
on the grip. ere are no separate manual setting rings on the lenses or camera body.
e chosen settings are displayed both on the grip LCD and in the viewfinder LCD. See the
‘Exposure Control’ chapter for a complete explanation.
Depth-of-field calculation
ere are two distance scales (in feet and metres) visible through the focus distance window
on the upper part of the lens barrel. ere is also a central lens index mark and a depth-of-field
scale. e focusing distance is read off the chosen scale from the central lens index.
Depth-of-field can be calculated as follows:
1. Focus the lens as required.
2. Make an exposure reading (auto or manual) and note the aperture setting.
3. Find the markings on either side of the central index that correspond to the chosen aper-
ture.
4. From these two markings, read off on the required lens distance scale the two corre-
sponding distances.
5. The depth-of-field (at that particular aperture and focus setting) will be the area includ-
ed between these two distances.
