Testing the new baby: Carl Zeiss Sonnar 180 f/2.8
Just a few shoots to test my new eBay acquisition, a superb Carl Zeiss Sonnar 180 f/2.8 ... Of course, the honor is for the King of the house ;-) ...
Merry Christmas (although late)

Mit dieser Kombination Pentax . . . + Sonnar 180/2.8 sind Sie in der gleichen Lage wie ich.
Nur sind die beiden abgelichteten schwarzen Katzen kaum für die Bildqualität aussagekräftig.
Ich habe mir dieses Objektiv per Adapter auch anpassen lassen, und nach ca 150 Aufnahmen aller möglicher Motive und dem Vergleich mit Aufnahmen von meinen für Kleinbildkameras hergestellten Objektive muß ich feststellen, daß die Qualität, weder der Tiefenschärfe, noch der Trennschärfe, noch der Farbwiedergabe auch nur im Entferntesten an Fotos meiner Kleinbildobjektive heranreicht - leider. Der Adapter war eine Fehlinvestition.
Woran könnte es Ihrer Meinung nach liegen? Das Objektiv wurde auf seine Qualität zuvor getestet.

Hi,
At first, thanks for spending your time here and commenting ...
Since i don't understand German, i have translated your comment with an online translator, which wasn't really a good performer (so, maybe i'm completely wrong with my answer) ...
So, if the translation is right, it seems that your Sonnar 180 on a digital camera doesn't perform well, while it perfectly works on your film cameras, and you are asking for an opinion on the subject ...
Actually, the Sonnar was mounted on my K10D using the original Pentax screw mount adapter, which completely flushes in the camera body when mounted. If your adapter doesn't completely flush (or if it has an external flange), you should loose the infinity focus but it shouldn't affect the image quality ...
According to the translator, you are experiencing a lack of contrast from your lens. This could be originated by a dirty rear lens (diffusing/reflecting the light that hits the CCD), but this is only a supposition ...
Actually, it is a bit difficult to try to diagnose a fault without having a picture of the lenses and a sample picture taken with it. If you could post a link to an online album with your pics, it could be easier to diagnose ...
Anyway, thanks again for your interest here and for commenting ...
