Hello Olsen,
From what I have been told, by Tony Rose at Popflash,
The Zeiss 1.5 50mm C-Sonnar was originally calibrated sharp at f2.8.
In early 2007 Zeiss (or Cosina) started to calibrate this lens sharp at f1.5 (probably after a lot of complaints, why else?).
C-Sonnars have been send to Germany to be recalibrated at f1.5.
I asked Tony for a C-Sonnar calibrated at 1.5,however he has no way of knowing which lens is in the box, as Zeiss is obscure in indicating which is which, a simple
indication on the box would have done the trick, my C-Sonnar now is also on its way to Germany, this could not be a money making proposition for Zeiss, you wonder at times what business model these companies are using including Leica up to a year ago.
Anyway folks if you need a lens, deal with Tony Rose at Popflash, he is the best person I have dealt with, ever, one only finds this out when thing go wrong and how it is dealt with, he looks after your interests.
Back to the C-Sonnar
For me, a f1.5 lens that not focusses properly(it may be somewhat soft,not the same as not focussing properly) open is not a 1.5 lens .
In my photography,when I am shooting portraits, the eyes have to be sharp,with the lens open, I don't want to guess at it or focus somewhere on the ear, If I want a out of focus shot , I can do that very handely myself.
My question in my earlier post concerning the calibration at f1.5 or f2.8 is related
to the image of the statues.
Shooting a statue has to be one of the simplest exercises in photography, the subject doesn't move, one can take his time in determining the focus point and exposure and shoot forever until one gets it right, no artistic endeavor required , serious photographers would probably use a tripod or monopod.
The implication of my question was simply: what what was the focus point ?, did
he rock back and forth to establish the optimum focus point and where did it end up.
Anyway, I would still like to know, is the lens calibrated at f1.5 or 2.8., however,
no reply is fine too, I am starting to loose interest.
Best Regards
Peter
