I am looking about the shop for an opaque dot to place over a 135mm Hektor filter. I wonder if it might approximate the Thambar. We shall see!

Better again.. :) you could take a B+W Soft Filter (they are regularly listed) and put ALSO an opaque dot on it... lot of years ago I made a similar test on my Rolleifex TLR (for which I have an original "Rolleisoft" filter) placing a black dot in the center : I didn't guess the correct exposure factor... and 120 film was too costly to be thrown away in trials&error... The Rolleisoft filters were no bad to use for portraits : they have 2 or maybe 3 gradations of effect... (I have 2) and were probably made by Zeiss (who listed its "Softar" filters).

From the same chi_rol_leica who published yesterday on Instagram a picture of the special edition 'LHSA 50th Anniversary' of the Leica Apo-Summicron-M 50mm f/2 Asph., the first picture of the Leica Thambar-M 90mm f/2.2:

UliWer, I hope you'll be convinced this time :p.

The abbreviation “mtr” for metre is not at all convincing.

The distance numbers are on a conical slice but are not distorted by it.

 

"mtr" is common Leica engraving from the 1930s - as seen on the original Thambar. http://overgaard.dk/thorstenovergaardcom_copyrighted_graphics/Leica-Leitz-thambar-2014-complete-set-640w.jpg

 

(and also on the 135mm and 73mm Hektors from that era, per the illustrations in my copy of Laney's Leica Collector's Guide (1992) p. 166 and p. 154.

...although to be complete, the exact engraving per lens bounced around a lot over their production lifetimes. "m", "mtr", "meters", "feet" or even

in some cases.

 

As to the engraving on the "conical" scale - compared with vertical "witness marks" added in Photoshop, that looks distorted to me (minimally, since it is only a slight coning from parallel).

None of which proves there will be such a lens - simply that there is nothing in the picture that says "fake."

 

jd: think again - 270 degrees would only just reach to the "horizon line" of the lens on the right side. The number and index line are far past that - more like 290-300-degree focus-throw.

Why "E49" , being E48 the original Thambar ? Anyway... if it's a fake picture, mixing a retouched original with new elements (DOF scale, Mount..) is very well performed :) ... the spot filter was probably a bit difficult to render from an original...

It's really VERY similar... almost like the Summaron 28 5,6 to its predecessor. (and why not keeping the old fashioned "9 cm" ?... oh well, also the 2,8cm has became a normal "5,6/28"...)

Looking well.. the only clearly visible difference in the main barrel of the 2 lenses is the absence of this milled ring...

Which can have a sense... the original Thambar had the lens head unscrewable (not for Visoflex, but for a focusing stage... there was a proper mount for it) , a feature that obviously there's no reason to provide now...

I am more and more convinced that isn't a fake picture... apart the post of Charlie Chan, the "mtr" can have been kept to mimick of the original.. and note, the fonts used for numbers (distances and f stops) aren't like the originals...and this has surely to do with the engraving machinery they make use of today... my residual perplexity is only about the filter size... but E49/E48 are so close... maybe they want the users of the new lens NOT rely on the "old" spot filter... :)

Same kind of product picture as others if you ask me. Was this one a true, a fake or a true fake?

Leitz/Leica marketing dept. has a longtime history of retouched images... few time ago, in the forum, we spoke about an old leaflet of the Leica IIIf with a Summitar "faked" as Summicron... times and technologies  have evolved... Net is widely used for viral marketing... but the principle ("titillate" the potential buyers) is the same B)
