Thats right, a very early Tamron, but not the earliest.
I have a couple of these.
Its a Tamron model 680 from @1962 as per the Adaptall site.
It is one of the earliest T-mount lenses also, but again not the earliest.
Tamrons first product from 1958 in fact was a 4.5/135 with matched TC, called variously a "Converto-Tamron", also a "Twin-tele". This 2.8/135 is a later variant of the same idea.
The price is way too high btw. Look for this thing under $30. Not a very common lens, but I wouldn't call it rare.

From the same official site, the earliest lens is the 135mm F/4.5 (Model: # 280) released in 1958

And though I have seen (and have) the 4.5/135 in various distributors brands (including all-alu finish types), I have never seen the 2.8/135 kit with TC as anything but a Tamron. The base 135 lens was also sold as a Soligor though (I have one too).

Did Tamron somehow market the convertos as an alternative to zooms?
BTW did you look at the other stuff on "Crazy Mama's Bits and Pieces", I wonder if they give you discount if buy something else too.

The early tamron lens may sold at low price since it was the first lens they ever made. So, they will be more common? |
