The Zeiss Myth...

I got this off of a side link from one Jeremy posted in the "Speaking
of Bokeh" thread. Hilights (blur circles may not be any thing or the
only thing to consider in bokeh (Zeiss lenses still have wonderfully
soft bokeh both sides of the focus plane) but if one were looking at
just hilight blur circles themeselves, both Nikon and the Cosina made
Zeiss may be something to steer clear of -- Pentax or Contax (Zeiss) or
Leica lenses instead anybody? :-)
http://www.kenrockwell.com/nikon/50-comparison/bokeh.htm
Of particular interest are the bottom paragraphs of Ken Rockwell's web
page that explain the Zeiss myth (as compared to the Nikon) and that
their hilight bokeh(s) are jokeh(s) and that their gaussian blurs are
currs (my phraseology) ;-) :-)
Too bad he didn't compare the 43mm Pentax Limited, the 40mm f/2?
Voigtlander SL lens (I know, not the same focal lengths as the rest of
the 50mm test lenses) and the Pentax 50/1.4 and 1.7 lenses against
those Nikon/Zeiss lenses but the test is already large and well done/a
service to people who care about bokeh (not to mention sharpness,
chromatic aberration and all the other factors he tested). Thanks Ken
for the test(s) (and Jeremy for the link).
Happy reading/viewing...

DC = "Defocus Control"

Re: The Zeiss Myth...

No I'm not ;-).
Totally agree with what you said, William. Good point or cicle of
confusion (pardon the pun). At f/256 all bokeh is equally good or
bad... or non-existant :-)
P.S. - I've never met a pinhole zoom tilt/shift lens I didn't like --
and that's no jokeh... well, maybe it is... ;-)

Re: The Zeiss Myth...

Maybe others? I thought that's the one we were talking about :-).
Minolta (before they were soNY (?soNewYork?) and before they were
Konica Minolta) had a 135mm f/2.8/T/4.5 STF (smooth transition focus
lens) that (along with other technology) I believe accomplished the
same thing as the Nikkor 105/2 DC ?Washington DC?, Direct Current?, DC
comics?).

Re: The Zeiss Myth...

Maybe others but there's a $924 105mm f/2 AF DC that's super sharp and
lets you select the front OOF or back OOF to have the softer bokeh by
changing spherical abberation without effecting sharpness.

Re: The Zeiss Myth...

The king of bokeh is a pin-hole camera:
I don't agree with this at all.....Exactly the opposite is true....In a
pinhole camera, everything is "in focus" (although not too well) There are
no "out of focus highlights" to give you either good or bad bokeh.

Re: The Zeiss Myth...

Everything is out of focus all the time....But, it's a good kind of out of
focus........:^)


William Graham


Re: The Zeiss Myth...

That's another lens. I forgot about it. But if I'm not mistaken it
isn't necessarily soft focus, in other words, the subject itself
remains sharp although the foreground and background OOF planes can be
adjusted to be smoother/sharper, I believe. Haven't tried it out, just
going by memory from what I've read either in camera/lens brochures or
on the web...

Thanks Chris, most M42 lenses were either before my time
(photographically speaking) or beinf phased out by the time I was
getting more serious about photography (1975-1981 time period, by the
time 1983 came about I was totally serious ;-)).
My 28-80 Rokunar - only two words can describe this lens -- "LEGALLY
BLIND"! -- (early 1980's off-brand with a lens set that probably came
from Leggo instead of any optical factory) was probably the pefect
example of a lens that was optimised for bokeh at the expense of
sharpness and every other factor, but I'm sure it wasn't intended that
way - just a crappy wish it was sharp enough to be crap soft lens.
Perhaps _the_ crappy lens! Gave new meaning to the word crap. By the
way, did I mention it was crap? I did? Good. It was crap. Just felt
like saying it again ("but what did you really think about it?" - it
was C-R-A_P!). Made you wish for the sharpness of at least a pinhole
lens ;-) Actually I heard that an earlier version of this lens was
sobad it was the real reason why Oedipus poked out his own eyes (that
and the quality of 6MP digital)...

Re: The Zeiss Myth...

How about the "Defocus Control" Nikkor?

Re: The Zeiss Myth...

I don't know if they were actually designed for bokeh or specifically
for their look (rather than just being cheap alternatives to more
expensive lenses), but the Meyer and Zeiss Jena Trinars & Triotars
(three-element, short telephoto lenses) are considered to be excellent
soft portrait lenses with a very special look.
Haven't tried them myself.
They are available in Exakta and M42 mounts - usually quite cheaply. A
real bokeh maniac should at least give them a try...
