lars_bergquist Posted April 4, 2012 Share #21 Posted April 4, 2012 Advertisement (gone after registration) I tried looking this up on the wiki, to no avail: what lens formula is the Thambar? Is it a Tessar-type? David It is basically a Hektor: four elements in three groups: 1 - 2 - 1 with the aperture stop after the cemented group.

Advertisement Posted April 4, 2012 Posted April 4, 2012 Hi lars_bergquist, Take a look here Old Thambar f=9 cm 1:2,2 found -> cleaning?. I'm sure you'll find what you were looking for!

The old man from the Kodachrome Age 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.

wlaidlaw Posted April 26, 2012 Share #24 Posted April 26, 2012 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! Wilson Link to post Share on other sites More sharing options...
Torquinian Posted May 2, 2012 Share #25 Posted May 2, 2012 I tried looking this up on the wiki, to no avail: what lens formula is the Thambar? Is it a Tessar-type? David 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. { Leica pocket book P196} Link to post Share on other sites More sharing options...

frank_dernie Posted May 21, 2012 Share #27 Posted May 21, 2012 Advertisement (gone after registration) I tried looking this up on the wiki, to no avail: what lens formula is the Thambar? Is it a Tessar-type? David 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. Link to post Share on other sites More sharing options...

kangaroo2012 Posted December 12, 2017 Share #30 Posted December 12, 2017 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? Philip Link to post Share on other sites More sharing options...

Philip Suggest you use it that way....you've got the EVF? All should work beautifully... Edited December 12, 2017 by david strachan Link to post Share on other sites More sharing options...
UliWer Posted December 12, 2017 Share #32 Posted December 12, 2017 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. Link to post Share on other sites More sharing options...
