RA> new autofocus H1 series and digital H1D, which are not Carl Zeiss by the
RA> way but Hasselblad lenses, where probably also designed and assembled by
RA> Hasselblad even though a lot of manufacturing is done in Japan.
AFAIK these are Fujinons, made by Fuji (as is the whole H1 camera, and
the X-pan film rangefinder). Which is not a bad thing, both are
gorgeous cameras with great lenses (just ask any LF shooter about
Fujinons).
Today, IMNSHO, "ED" glass is quite a meaningless term. It doesn't say
anything about the good or bad of the lens, nor about its aberrations.
It doesn't mean the lens is Apochromatic. It doesn't even hint at it.
Same with "APO". Also, I have never saw any manufacturer actually
disclose what actual index does they mean by e.g. "ED" designation,
and how much "extreme" it is compared to "normal" glass.
Pentax was always quite conservative in its lens designations, which
was good - but today market terms are more important than actual
quality, so they must adapt to the market which asks for lens names
longer than the lens barrel itself!!!
Good light!
