First i would like to say that the Phrases "Closed System" and "Locked" are Phase generated. Hasselblad created the first integrated DSLR in 2004 with the H1D followed by the H2D in 2005.
There are tremendous benifits of having a system that is completely integrated and Hasselblads competitors are following suite with their first generation DSLR cameras.
We have a very unique advantage whereas we have a hand in designing and manufacturing everything from the Digital magazines, Bodies and Lenses. Yes, we do have an optical design team in Sweden that has designed every HC and HCD lens. We provide all MTF data on our website so photographers can compare optics wether it be an HC/HCD or Zeiss lens. We manufacture the electro-mechanical shutter at the factory in Sweden.
Lens corrections are not specific to the 28mm HCD but across the spectrum of 11 HC/HCD lenses from 28mm to the 300mm including the 50-110, 35-90, HTS 1.5 tilt shift, 3 extension tubes, 1.7x tele-converter. Hasselblad has created in excess of 50,000 data files, mapping each focal lenght at every aperture and focus distance with each combination of above items.
Does C1 use generic lens data for Lens + or have they gone through the process of mapping every optic? I already know the answer to this question ...
This is a technical decision rather then a marketing decision. Hasselblad designed their first digital HCD lens to cover the image circle of a 22/39/50mp sensor, the 28mm was announced at Photokina 2006 Hasselblad at the same time we announced our 3rd generation H3D platform 2 years ago.
It is relatively easy to design a lens dedicated to specific sensor dimension that is sharp edge to edge that exhibits a small level of distortion which can be corrected in software, thereby reducing the weight, size, and offer an overall cost savings.
Hasselblad was the first any medium format company to introduce DAC (digital auto corrections) and now years later companies are following Hasselblads lead and trying to implement the same. We have 3 levels:
Level 1: Chromatic Aberration correction
Level 2: Distortion correction
Level 3: Vignetting correction
You can certainly remove the H3DII digital magazine and mount it to any technical camera that has an H mount. Power can be provided via our 100GB Image Bank II with a standard Sony InfoLithium battery attached, shoot tethered to laptop or use the HTS (tilt-shift) with your H1, H2, H3DII camera:
