Really like this Brian, reminds me of a Japanese watercolor. In your first comparison shots of the fence post the coated lens appears soft at f1.5 or is it just the coating making it appear that way because the color is more saturated? but then at f4 it sharpens up. Anyway, nice find you have there. 🙂

The first shots are with the Olympus EP2: The Anti-Aliasing filter and thicker IR absorbing glass cut into the "pop". After conversion to LTM, I used the M9 for the shots.

Dexdog- it really is a beauty of a post-war Sonnar. someday I will figure a good way to convert "1 of my other 3" of them to LTM.

The 1951 Jupiter-3 focus mount is one of the smoothest that I have seen, great helical. The glass had some damage to the cement of the rear triplet, and some fungus on the inner surface of the front element. The rear triplet was uncoated german, hard to find a perfect match for. At some point- i will make it into a Contax mount lens.

I have one pre-war lens engraved "made in germany", and it is a SN160 block lens, circa 1934~1935. Black trim on the mount. Probably Export version.

The pre-war Sonnar "T" lenses would have a SN of less than 270xxxx. I would be surprised if any were exported, as the coating process was a "State Secret".

It would have been easy to transplant the optics module into an earlier mount. I've done that, when a latch pin broke.

Post a picture of it on a thread here- we'll have a look.
 
I have several pre-WW2 Contax 8.5 cm, 13.5 cm and 18cm lenses stamped "Made in Germany" and all are marked in feet, not meters. The only 5cm lens that I have with the Germany stamp is a 144 series lens that has a distance scale marked in meters. Go figure.

Okay well here it is. Under a hundred dollars from eBay courtesy of bad auction photos and overly critical description. Glass looks really good to me, there are what appear to be numerous bubbles near the rear element inside, shown on last photo. Does not appear to be dust. I need to get it out in the light of day and try it out. Barrel looks extremely clean compared to my 1934 uncoated Sonnar.

Does not say "Made in Germany" but I guess that would indicate it was not an export lens, which makes sense with a T coated lens circa 1939.

Note the proper (?) CZJ lens cap!

Fantastic find.

Patience, Luck, fly in below the RADAR screen. I picked up the Black-Trim Sonnar much the same way. The seller stated it needed a really good cleaning, glass looked awful in the pictures. The seller was correct. Needed a good cleaning.
