The Leaf Aptus is now the third MF back (22MP) that
we used untethered on a Hasselblad H1.
All these backs work completely untethered with battery in/on the
unit and CF cards as storage.
The biggest visible difference between the Aptus and other backs is
the huge 3.5" touch screen LCD . We did not get any manual with our
review unit. But the clear online menus made working very easy and
we were up to speed in about 20 minutes.
In strong sunlight the LCD is hard to read. The unit
we got came with a Hoodman shade (used normally for video cameras)
helped to shade the LCD. As we understand Hoodman plans to develop
a more suitable hood.
The shoot menu provides you with all
the info you need:
- Histogram as shown
- Larger histogram overlay with RGB channel histograms
- Overexposure indicators on demand
Overall the LCD is very helpful to view images and work with the unit.
Note: While the Aptus stores images
from the internal buffer to the CF card some of the operations on
the LCD cannot be performed (e.g. changing ISO).
For outdoor work we think that the Phase One P25 with its more limited
LCD is as practical as the Aptus. But of course the Aptus would allow
a more detailed inspection of the images if you find a shaded place.
We use the uncompressed raw mode on the Aptus (files are 41MB large)
because ACR 3.x can right now only open the uncompressed files. The
Aptus also support lossless compressed raw files that take up only
about 50% of the space. Probably future versions of ACR will also support
the compressed files.
