I just bring home Carl Zeiss Jena T Sonnar 5cm 1,5 LTM (together with three other LTM beauties 😀).
S/N 2789314 dates the lens in 1941 (source: http://home.sprynet.com/~stspring/Zeiss%20Ikon.html).
Any info on the lens?

This looks like a post-war remount of a Sonnar, into LTM. I've seen some unusual ones done. It does not have a regular production focus mount, looks more like a custom job.

Try the lens out on, check close-up and wide-open.
 
The barrel does have S/N as well as you can see from the last two pictures and the material seems to me same as the lens material so I dont think that it is a custom job but factory one.

Definitely custom job.

The barrel has a serial number that is completely different from the lens serial number and that would be the same number if it were a factory conversion.

the way that serial number is stamped in, it reminds me of the FED collapsible 50/2.0 I own. That has the same messy stamped number. Zeiss Jena would never do it like that.

Question: How do you focus this thing? Don't see a focus scale on it anywhere. maybe it was remounted to be used as an enlarger lens? These have 39mm mounts from some manufacturers.

I'd ask Brian to fix it into an early Jupiter-3 barrel and make it resemble the real thing, usable and all!

Nice find! I've been to Prague, did you find it in a shop over there!?
 
I pruchased few lens from the collection after late photographer. Lens was mounted on the Canon VI that I left behind.
The big barrel is firm on the camera when the lens is mounted, focusing is done by turning the ring under the f stops.
 
The serial number is not displayed in Thiele's book, but late 1941 seems to be a pretty good time period based on serial numbers close to your lens. Looks like a custom re-mount to me, too.
 
Pretty wild looking mount there, but the Zeiss lenses were such a reknowned item in the late 1940's and early 50's that photographer's would try anything to get one to work on a LTM camera......

#278xxxx were postwar era lenses, from the 1945/47 RAOO period, looks like a custom remounted lens, not a Zeiss factory conversion.

If it has really good clear glass and the mount works focus/sharp to focal plane then you should have a really great shooting lens have fun with it! 🙂

nice Sonnar you got there! optics elements look good and lens barrel not too bad either, given the age.
 
The seller doesn't claim it is original mount.

It is made from real Zeiss Sonnar optical elements, which have been custom remounted on a third party screw mount.

If you look at the chewed up front ring and screw heads, it is obvious the lens has been taken apart by someone who was not as careful as they should have been.
 
The mount is perhaps taken from a "rigid" soviet industar 22... looks like a backroom job. Useful lens perhaps, but a kitchen table franken imho, too costly at 400 bucks.

What S.H. says. Not a particularly pretty job.

Did you inquire about the camera that was used to shoot the test shots with?
With a modern EVF camera or with Live View, you can make any lens produce sharp pictures but that doesn't necessarily mean it will focus correctly on a rangefinder camera...

Happy shooting nonetheless, if it gets you what you want, all the better!
 
Dear All:
I've got a Carl Zeiss Jena T Sonnar 5cm F1.5 LTM with brass barrel from e-bay. The lens is not like I usually saw from e-bay.

The result from the lens with M9 is very pleasant, with smooth bokeh. Can anybody help me to find more information about this lens? Such as is this a true CZJ or Russian copy, the year it was produced, etc. Thanks a lot in advance!

I've watching the forum for a long time, but haven't posted before. Nice to have my first post here!!
