ZeissT 1.3 lenses VS Cookes S4 T2
Posted 09 September 2008 - 08:51 PM
Has anybody done any comparison tests of the zeiss T1.3 vs the S4 Cookes? I shot a test today and I am waiting for the results. The test was a small one with only the 25mm of both makes. Has anybody done any excessive tests?

Personally, one large deterrent for me, however, is the shape of Cooke's aperture blades, which turns out of focus lights into distracting multi-pointed stars, even wide open slightly since the blades never completely open to the full width of the barrel. This can often be seen even with a tree in the background, as evidenced by points of the sky peeking through the leaves. Superspeeds have less blades, 6 or 7 if I recall, but at least make a less jarring, non-pointed hexagon. At T1.3 lights become circles near the center, and increasingly narrow "footballs" near the edge, due to vignetting at wide stops. That, with the astigmatism, the SSs can produce an interesting, round, often pretty swirly soft focus look wide open if that's ever what you're going for. The newer lenses are more corrected and 'neutral,' but lose some of the personality and magic of what wide-open photography can be.

They haver 7 blades.
Superspeeds have less blades, 6 or 7 if I recall,
I agree that the Cooke S4 bokeh is very distracting.

I'm not sure, but an optical engineer once told me that comparing MTFs by different manufacturers is risky, e.g. Japanese manufacturers usually only calculate their MTFs while Zeiss/Leica/Schneider measure real production samples. There are many ways to "manipulate" the MTFs, I would only use them to compare lenses of the same manufacturer.
