Hi all,
Here is something that caught my eye.
Digital correction in software of optical design problems seems to be
coming to the market place, something new to me, though it has been
theoretically possible for some time.
Here is an exerpt from a short article in Digit, which says about
itself, "Digit is the UK's leading resource for creative
professionals, both in print and online." The article is entitled:
Leica, Hasselblad Show New Digital Cameras, Wednesday 27 Sep 2006 -
09:20, and can be read at:
http://www.digitmag.co.uk/news/index.cfm?NewsID=6201
After discussing the new Leica cameras, the article goes on to say,
"Hasselblad launched what the company claims to be the world's first
48 millimetre full-frame DSLR camera." Here is the later paragraph of
interest:
"The camera is built around a new digital camera engine. Information
about lens and exact capture conditions are fed into the engine for
ultra fine tuning of the auto-focus mechanism, taking into account
the design of the lens and optical specification of the sensor.
Another feature is Digital APO Correction (DAC)."
What this "feature" means for new and old lenses is left unclear.
Can new lenses now be constructed more simply by using this mode of
optical "correction"?
Can older lenses have their performance "improved" by a one-shot
measurement of their inadequacies and the prescription of a digital
correction?
As ever,
Bill
