I have a chance to get the earliest model of CZJ Sonnar - the olympic 300/4 based on the original 5/3 Sonnar formula. I understand, the lens is rare, but I'm curious if anybody has experience with it (sharpness, bokeh, CA...)
Thanks

Is this lens so rare? I must say that this is the first time I have chance to buy it. I saw Biotar 75/1.5 about 3-4 times for sale here, Primoplan 75/1.9 and Helios 85/1.5 once...

Is this the Pentacon Six 300/4 Sonnar or a different design? If it is the P6 one it is a typical Sonnar, very sharp even wide open with some slight magenta/green CA in adverse lighting conditions. It's a very good lens but not a lightweight.

There are at least 4 optical designs of Sonnar 300/4 (I think these images posted koji months ago):
1. Sonnar 300/4 Olympia
available in M42 and Exacta mount, some copies have T-coating, optical block is in front of the aperture
 
2. Sonnar 300/4 zebra
P6 mount, slightly different optical formula (maybe it was recalculated + zero lens added to close the aperture inside)
 
3. Sonnar 300/4 black
another optical formula, available with or without MC
 
Sonnar 300/4 Prakticar
last optical formula (not a typical Sonnar, in fact it's Ernostar-based), MCed, praktica mount

I own one copy too. Mine is heavily used, but according my comparison, it is up to f5.6 still comparable sharp to my former mint copy of '92 MC Tair 3s. At f8 the Tair was sharper with almost zero CAs. But Sonnar suffers from more CAs and LoCAs at all apertures. It delivers very good contrast and colder color rendering in comparison to warmer Tair. Nice collectible item, but optically nothing to rave about. Even my el-cheapo Revuenon 5.6/300 is at f5.6 sharper.
This is third copy I see for sale in Czech Republic in last 4 months. Including mine.
Bokeh, contrast and colors at f5.6:

These are a bit wrong however:
Both the black and the zebra version have the exact same optical formula:
After the black version there was tbe lightweight (maybe 500 grams lighter, still heavy beast) black version:
Finally there is the Prakticar 300/4. Koji has the wrong image for it on his site - on the bottom of this image one can the proper diagram for the Prakticar-version (though it is read froom right to left instead of the normal left to right):

Anu: Thanks, I'll check the MC model as soon as it returns from service. Btw. do you think, that this diagram isn't related to any Zeiss 300/4 lens?
back to topic... here are my first shots with the Olympia Sonnar T 300/4 (all at f/4):

Hi,
according to the Sonnar 4/300 section in
https://zeissikonveb.de/start/objektive/wechselobjektive1950er/carl%20zeiss%20jena.html
the following first three lense schemes are correct, while I never saw the third scheme - which isn't a Sonnar - as non MC. In fact however there are black versions of the second scheme, which not only share the second optical formula but also the shape of the lense barrel; I own that version (https://www.digicamclub.de/showthread.php?t=23197).
The second (Zebra) scheme from 1963 has two differences to the first scheme of 1940: there is an additional flat lense to save the diaphragm mechanism, and there is an airgap in the second group.

The last lense scheme is according to Prakticar 4/300 in
https://zeissikonveb.de/start/objektive/wechselobjektive%201980er/carl%20zeiss%20jena.html
also correct for the second version of this lense what was the first to be produced in higher numbers. It is related to the lense scheme of the rare Prakticar 2.8/200. The lense scheme of the third and last version of the Prakticar 4/300 however can be found at the link above and in the there cited patent and looks like a mixture between the "MC Sonnar" (third scheme on the top which isn't a Sonnar) and the 1963 Sonnar (2nd scheme on the top):
Source: Volker Tautz, Günther Benedix: Fünfgliedriges fotografisches Objektiv
Though not really beiing a Sonnar (e.g. due to air gaps and different radii) it is somehow more Sonnarish than the third and much more Sonnarish than the fourth scheme in the cited pictures which was produced before. The patent also states that the problem of the second version (4th cited scheme) has its problems in the first two lenses: due to strong ray deflections of the first two lenses those must be mounted very precise in order to achieve good lense quality. In the third version the basic idea was to procede (go back?!) to moderate ray deflections, in order to allow for less mounting effort.
