Sure, There are not too much things under the sun, which are
really new. - But who know`s only that thing`s change when their time is come.
So there may appear new aspect`s to an old topic, when it`s discussed again.

I` confused about what`s meant with that. Maybe another issue to
improve my English??

I don`t belive that it is impossible to use Zuiko`s with digital-sensor-chips.
I guess the foils are fine excuses. Altough I`m sure, that it`s only a "second
best solution" to reconstruct existing film camera`s for digital use.
There are efforts to produce digilal-film for all camera`s:

And last but not least, Am I looking at a nice prospectus of the
Olympus/Hasselblad -Macro -Foto -System. A modification of the
Olympus-Auto-Bellows
and the Macrophoto Stand to fit either Olympus OM or 6x6 Hasselblad Cameas.
They point out,
that it is possible to use several digital sensors available for Hasselblad
bodies to use with this
System which is based upon the Olympus Zuko Macro Heads (135 F/4.5; 80 F/4;
...).
Sorry I can`t find any information on the Internet about that.
So what? - I`m sure it`s aQuestion of price/ value/ demand, and that may change
fast when technology (of digital sensoring) goes ahead. - Just my HO.
