Lens corrections can be applied when captures are imported
into Phocus. Guided by the information in the metadata in-
cluded with each individual capture, the DAC (digital lens cor-
rection) tool uses lens-model specifi c calculations to adjust
for chromatic aberration, distortion and vignetting. Not only
model specifi cations but also capture parameters are taken into
consideration for analysis.
This extremely capable refi nement of captures should not be
overlooked when processing fi les! See Phocus user manual for
details.

Specifi c-lens information
Some lenses have extra characteristsics that require further
explanation. This can be found in the "HC Lenses" data book-
let that accompanies each lens. The booklet can also be down-
loaded from the Hasselblad website.

Attaching a lens
1
Remove the front protective cover on the camera body by de-
pressing 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 fi tting) until it clicks into place.
Removing a lens
Depress the lens release button and keep it depressed while ro-
tating the lens counter-clockwise until it stops and lift it out. Re-
place protective caps on the lens immediately and on the camera
body if necessary.
If you try to rotate the lens before you press the lens release but-
ton, it might lock. In this case, rotate the lens clockwise a little fi rst
and then re-attempt removal with the correct procedure: button
fi rst, then lens.
Front lens cap
Front lens caps are released for removal and attachment by in-
serting a thumb and index fi nger into the recesses and pinching
in the direction of the arrows.
Filters
Filters have a screw thread fi tting (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, fi lters do
not rotate either. This is particularly useful when using polarizing
or graduated fi lters where the orientation is normally critical.
Lens shades
All lenses are supplied with lens shades that additionally pro-
vide extra protection for transport and storage when mounted
in reverse. Lens shades have a bayonet fi tting 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 sepa-
rate manual setting rings on the lenses or camera body.
The chosen settings are displayed both on the grip display and
in the viewfi nder display. See the 'Exposure Control' chapter for a
complete explanation.
