Who's throwing rocks at my window? :ROTFL:
This discussion has flipped back and forth between a 31 and 40 meg sensor. Can't speak to a H4D/31, never used one ... can speak to a H4D/40 ...
Have done T/S work with the H4D/40. I use the Hasselblad HTS unit for most of it. Max shifts for panoramic landscapes, and tilts in studio for product work to increase DOF, or for portraits to control OOF areas ... with no additional post corrections other than those programed into Phocus (I posted panos in a thread about this including close ups of the corners and edges, and some are still in my GetDPI gallery).
When occasionally needing both front and rear standard movements ... which the HTS and tech cameras like an ALPA do
not provide, I use the a Rollie Xact-II ... which requires shooting a white calibration image and use of Phocus software features when using my Schneider 28mm ... which admittedly I use infrequently. Most of this is done tethered in studio or on location. I have shot with T/S on location requiring use of the Image Bank-II to provide power, but it does facilitate rapid capture and
redundant storage of up to 800 to 1000 images for back-up when shooting once in a lifetime images or non-repeatable events/set-ups. Not comparatively ideal for climbing down into some exotic location, but possible. So, other than the omission of the power source requirement, the literature on the H4D/40 is correct as far as I am concerned.
In addition, unlike 40 meg Dalsa sensor backs, the H4D/40 can do up to 4+ minute exposures and very clean ISO 1600 at full resolution, not MFD resolution from 10 years ago ... which I have also posted images of in a thread. Depends on what's important to you.
That said, if someone said they were very interested in a tech camera such as an ALPA and wide angle lenses for mobile field work, I would refer them to someone that owns and uses one, since I do not.
Personally, were I very interested in that as an
exclusive camera platform, the
only DB I would look to is Phase One. Hassey requires use of the Image Bank-II or separate power source plugged into the back for field work, and other solutions such as the Hassey CF backs and Leaf Aptus require a battery hanging off the DB, Phase doesn't. Personally, I wouldn't even consider anything other than the new IQ backs for this type of application since focusing tech or view cameras with movements is VERY difficult, and the new IQ backs have innovations that clearly aid in that chore.
However, I am NOT interested in a tech camera as an
exclusive platform, preferring the fully integrated H4 system diversity and option of the HTS, waist level finder, 35-90D lens, all leaf shutter optics, True Focus/APL, etc. For anything close to that diversity with a Phase One back I would have to use a tech camera and a Phamiya 645 camera ... which is the last camera on earth I would personally choose no matter how many band-aids they put on it. Love the backs, hate the camera.
Again, depends on what is important to you because nothing is perfect for all uses in all degrees of applications ... something gets compromised somewhere. BTW, comparing a H4D/31 entry level system to a full blown Phase IQ kit on an ALPA or other exotic camera worthy of such a back, is a financial anomaly of titanic proportions
You get what you pay for.
