Hi!



I saw this on that auction site. It didn't sell. Here is the link to the auction, in case you want to follow it:
http://www.ebay.com/itm/AETNA-ROKUNAR-200-mm-Lens-1-3-5-No-187200-Used-/151082707843?orig_cvip=true

It looks almost the same as a Tamron Adapt-A-Matic 200/3.5 (not Adaptall or Adaptall-II). Is it? If not, what is it? And who/what were Aetna Rokunar?

Cheers!

I think it is made by Tamron too: http://adaptall-2.org/lenses/870Au.html

Old thread for the 5.6/300

I believe so.

One of the undocumented fixed mount types similar to the ones sold as "Vernon Edonar".
The M/A switch style is an identifying feature.
These were usually similar to corresponding Adaptamatic, but not always.
The 200/3.5 had some differences from the 200/3.5 Adaptamatic I believe. Aperture and min focus.

Hi!

calvin83 and luisalegria, thanks for your help. I like the Adapt-A-Matic concept in these old lenses much more than fixed mount. Still, I'm happy to hear that my tentative identification of this lens as Tamron-made is likely correct.

Cheers!

Here's a picture of my Tamron Adapt-A-Matic 200/3.5. It looks very very similar.



Not a bad lens.







Happy shots!

I always thought it was a pretty good lens.
I still have not finished a portfolio for it, I should.
