The gauntlet is thrown down to the MF back manuafacturers:
"...Consider, too, the question of continuity, a matter of considerable relevance when the
purchase of an $8,000-or- more camera is on the table. Where the EOS-1Ds MarkIII is
completely compatible with virtually all vast EOS System, and can be expected to
remain compatible—and supported—for decades to come (note the current software
support for the D6000 and D2000), today’s medium format digital backs often do not fit
even recent products from the same manufacturer. Will a newly-purchased component
be compatible with same-brand software and hardware in the not-too-distant future?
Betting on, and investing in, the EOS-1DsMarkIII isa sure thing." http://cpn.canon-europe.com/files/news/pro...-Whitepaper.pdf
So is this a valid point or just marketing spin? I'm sure Contax owners (not a digital back manufacturer I realise, but a warning none the less?) can relate to this. Are Mamiya owners feeling nervous? Pentax fans have just had their hopes dashed. What about those who bought the Fuji MF back? Or the Kodak backs?
