I agree with you 100%
I had one on loan for almost a year, 2.8A w/ Opton Tessar
80/2.8 and 1/500 Compur Rapid. It took great photos IMO.
The front cell focus version on my 6x6 Super Ikonta wasn't
bad either.

Thanks for the information. As I mentioned, I am just
curious if any "improvements" were made to the design. I
am quite happy with the performance of my particular lens.
Even wide open, this lens has useful applications, and
actually isn't as poor a performer as ancient lore has led
us to believe. For proof, type "Rolleiflex A, 2.8 Tessar"
into the search engine at photo.net. There I have
uploaded several images, several of which are at 2.8
Ciao,

I once asked if anyone had an Ikoflex III and if they
would comment on the lens quality. I heard from only a few,
after all the camera is pretty rare, but the quality seems
to have been at least OK. Of course, the front cell focusing
lens is an entirely different design. There is not a lot in
the literature about front cell focus design, I think
Kingslake has an article about it in one of his lens design
books. Overall the correction must be compromised. The
Super-Ikonta lens seems to be a particularly successful
design. The Super-Ikonta B (the only one with an f/2.8 lens)
also has an excellent rangefinder which, I suspect, has a
lot to do with its reputation for sharpness.
