I tried looking this up on the wiki, to no avail: what lens formula is the Thambar? Is it a Tessar-type?

It is basically a Hektor: four elements in three groups: 1 - 2 - 1 with the aperture stop after the cemented group.

Exactly... on the contrary I think that the other "superluminous long focus" of the era - Hektor 7,3 cm f 1,9 - is of a different breed - Summar style... isn't it so, Lars ?

No, both the Thambar as well as the Hektor 7.3cm are "Hektor style" - which means they are derived from the classical triplet. The summar, however, is a double gauss planar type.

Stephan,

 

A bit of fungus may just add to the charm of a Thambar ;-}} Seriously, given the value of this lens, I would only send it to a recognised professional specialising in historical Leica lenses. If you advise what country you are resident in, I am sure a forum member will be able to help you with some recommendations. In the UK, Malcolm Taylor is the expert on historical Leica lenses and although occasionally slow, does a great job.

 

I don't know what happened to my father's Thambar. I suspect it went to the local jumble sale, failed to sell and was then chucked - weep weep!

It is thought to be a Hector with the first and last group each replaced by a single element.No-one seems sure, but I have seen one in the International price guide valued at $3600 if it has all the bits or $2500 just for the lens.

I recommend the Erwin Puts books for the lens formulas, amongst other things.

The Thambar has 4 elements with the middle two cemented. It is not a Tessar type.

It is a bit like a simplified Hektor.

[jaques]

his may be a stupid question but would it be remotely possible to turn a hector into a thambar?

[jc_braconi]

Can be ....I mean about the question...

My Thambar was found in an old QANTAS airline bag from the 1960s with a water immersed Rolleiflex

and other odds and ends.

My problem is attaching it to an M10. The camera indicates "no lens attached" although I am using a Leitz M3 adapter.

On the MP (240) it works with live view and is manageable, using the same adapter.

Anyone have any ideas?

Suggest you use it that way....you've got the EVF?

 

All should work beautifully...

The M10 has a bug : when the patch to read out the 6bit-code is not fully covered it will „think“ that there is no lens attached, so you cannot use LV. The M (Typ 240) had the same in the beginning but it was solved by firmware update.

 

With a 90mm lens you can get adapters which have no spareout at the position where the is 6- bit code is read; then it should work.
