I don't think you are making any sense whatsoever .
I appreciate that there might be some complications in making this camera/digiback, but I would have though that most photographers could get their heads round the concept.
Most DSLRs many of the functions that are only available when you have the camera, digiback and view finder all assembled as a unit... and when you remove the digiback to attach it to a view camera or pancake camera you lose many of these features,,, and you do no get live view on the back of the camera, or in a pseudo-SLR type view finder...
If they can put live view on £300 cameras, why can we not have it in £15k to £30k cameras?
Do you appreciate the problems of wide angle?
Good wide angles are non-retro-focus and cannot be used on SLRs, Arch users would like the simplicity of an SLR when using 90 degree lenses.
