D. Depth-of-field scales
E. Lens index
Attaching a lens
Remove the front protective cover on the camera body by depressing the lens release
button and keeping it depressed while turning the cover counter-clockwise. Remove the
rear lens cap by unscrewing it in a counter-clockwise direction. Align the index on the
lens with the index on the camera body and rotate the lens clockwise (bayonet fitting)
until it clicks into place.
Removing a lens
Depress the lens release button and keep it depressed while rotating the lens counter-
clockwise until it stops and lift it out. Replace protective caps on the lens immediately
1
and on the camera body if necessary.
If you try to rotate the lens before you press the lens release button, it might lock. In this
case, rotate the lens clockwise a little first and then re-attempt removal with the correct
procedure: button first, then lens.
Front lens cap
Front lens caps are released for removal and attachment by inserting a thumb and index
finger into the recesses and pinching in the direction of the arrows.
Filters
Filters have a screw thread fitting (67 / 77 / 95 mm, according to lens) and are screwed
clockwise into place. As there is no rotation of the front section of the lens when focus is
changed, filters do not rotate either. This is particularly useful when using polarizing or
graduated filters where the orientation is normally critical.
Lens shades
All lenses are supplied with lens shades that additionally provide extra protection for
transport and storage when mounted in reverse. Lens shades have a bayonet fitting
and are turned clockwise into place after 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 clockwise.
Shutter and aperture control
Both the shutter and aperture are electronically controlled and are adjusted by the
control wheels on the grip. There are no separate manual setting rings on the lenses or
camera body.
The chosen settings are displayed both on the grip display and in the viewfinder display.
See the Exposure Method chapter for a complete explanation
Depth-of-field calculation
There are two distance scales (in feet and metres) visible through the focus distance
window on the upper part of the lens barrel. There is also a central lens index mark and
a depth-of-field scale. The focusing distance is read off the chosen scale from the central
lens index.
