Yes, both the red triangle and the front barrell leters looks faky. Not mentioning the mount.

The more interesting question would be does the seller know (thus fraudulent) or does he just re-sell it without barely having a clue about.

No idea there. I went through the other lenses the seller has on ebay. They all look authentic. It's a bottom feeder's grab bag though. Old lenses with assorted strange mounts, many look like they were designed for permanent lens cameras so would need unique adapters. If I had to guess this guy buys at flea markets, bonnet sales etc., possibly in job lots, and sees so much strange junk that nothing grabs his attention as real or fake. Just list it starting at a Euro and let the market decide.

In my admittedly not expert opinion, a fake.

1. It says it is a Zeiss Jena lens but the red T mark is a Zeiss Opton coating trademark, Jena couldn't use it.
...


Carl Zeiss Jena has been using the red T mark even during the war - i own several coated civilian wartime lenses from Carl Zeiss Jena, among them two 1.5/5cm Sonnars and a 2.8/3.5cm Biotar. They were sold during war time to neutral countries such as Switzerland and Sweden. Two of them are shown here: http://www.artaphot.ch/zeiss/objektive/203-sonnar-5cm-1-1-5.

EDIT: obviously Carl Zeiss Jena was using the red T mark also during the 1950s; see image attached (image from Internet, not my own)

Capital M vs small m on the focus scale is one clue.

Of course i also think the lens shown in the first is a fake. I only wanted to clarify that the red T mark was used by Carl Zeiss Jena (pre-war), by Zeiss Opton/Oberkochen and by Carl Zeiss Jena (after the war).

Thought I'd share this picture from a local auction site. Looks fake to me, but this is a first time I see a cutout at the distance marking on the outside.

I have seen several Sonnar 5cm F1.5's "cobbled together" immediately after the war. They are not "fakes", but not regular production lenses. This latest lens may fall into that category, you would need a closer inspection. The original lens shown from 2016 looks like a Jupiter-3. 20 years from now the 50 or so 5cm F1.5 Sonnars that I've converted to Leica mount using a J-3 focus mount will be giving people fits trying to determine the origin.

According to this, if the distance marking is marked with M, it is a fake, but it could be wrong.
