(extending previous thread on EOS-list, CC to PhotoForum list for
technical novelty of the constellation)
Hmm....not much reactions on my previous posting about this topic on
the EOS-list, where a Novoflex-reverse-mounted EOS zoom was found to
be equal in quality to a Zeiss Luminar....;))
http://www.weihenstephan.org/~joachenk/makrozoom.html (sorry, all
German; the summary of that article is that the quality is explained
(and confirmed by Zeiss!) with the fact that the reverse-mounted
lens uses only a very small center part of the original optics, and
that center is relatively easy to design near-perfectly (a similar
explanation exists for the question why the EOS 24/3.5 tilt/shift
lens hardly looses any quality when combined with a 2x converter).
But perhaps this second thought will get some more attention:
The zoom used in this reverse-constellation is a 28-135/IS.
And I see no reason why the Image Stabilisation might not work in
this case.
So effectively you have a zoom-micro ranging in focus/magnification
from infinity at 135mm to 3:1 at 28mm, handholdable at that point up
to 1/8s at least, 1/2s or even 1s most likely, especially when
combined with a monopod.
Also a rather cheap alternative to the only other zoom-micro's out
there, a Zeiss Tessovar or Zoom-Luminar....:))
(with the difference that these are relatively (very) long tele's,
and offer a much better subject-distance)
