Note
Some lenses have extra characteristics that require further
explanation. For example, the autofocus range on the HC
4/120 Macro lens can be limited by a specic setting on the
camera allowing for near range, far range or full range. This
only appears on the grip display together with that particular
lens.
Further information can be found in the "H-system Lenses &
H-system Lens Accessories" booklet that accompanies each
lens. The booklet can also be downloaded from the Hassel-
blad website.
Also, see note here regarding HCD lenses!
Note
Lens corrections can be applied when captures are import-
ed into Phocus. Guided by the information in the metadata
included with each individual capture, the DAC (digital lens
correction) tool uses lens-model specic calculations to adjust
for chromatic aberration, distortion and vignetting. Not only
model specications but also capture parameters are taken
into consideration for analysis.
This extremely capable renement of captures should not be
overlooked when processing les! See Phocus user manual for
details.
Note
The autofocus function is not possible with certain combi-
nations of lenses and accessories. However, a warning is dis-
played which disappears after conrmation.
Tip
The True Focus function can also be combined with other
autofocus modes for specic situations.
Tip
To expand your range of lenses, consider using a CF adapter
to allow you to use most of the lenses from the Hasselblad V-
system.
Tip
For users who prefer manual focus control but would like the
benets of autofocus, one method is to set the AE-L button (or
any customizable button) to AF (Single) drive.
The main subject can then be centered and the AE-L pressed,
to ensure correct focus. The camera reverts immediately to
manual focus control when the button is released.
Therefore, you can recompose the picture without having to
maintain pressure on the release button in order to retain the
newly automatically made focus setting (AF-T can also be
used).
Note
HCD lenses were formulated for use with the smaller size
sensors in the H-series, resulting in a reduced coverage for
the larger sensors used in 60 Mpix models. So, if you use HCD
lenses, be aware of the restrictions (vignetting and diminished
quality at the edges).
As notication of this situation, an auto crop function is
employed and an HCD crop icon appears on the right hand
side of the viewnder display when an HCD lens is tted.
When in Phocus, however, the auto crop function can be
turned o in Preferences if you wish.
