Can someone please help identify this Super Takumar 55mm f2?

As above. I've looked at the available photos and my copy is not one of them. Thanks

It's the first model with the reversed aperture ring.

Confusing because is it sitting on a Nikon (mounted or unmounted?), with the f/stops on the aperture ring at the bottom.

a) Someone thought a FF Nikon DSLR would be a good tool to use as a base for shooting this lens?
b) The M42 mount has been modified for Nikon?
c) The Nikon has an M42 mount adapter?

That thoriated glass is quite yellow. @boriscleto is spot on, but the way the lens was shot puts some doubts in my mind if the lens was modified for a Nikon mount.

The first Takumar with a reversed aperture ring was the Auto-Takumar 55/1,8 from 1960. It came with the Pentax S 3, and was exactly the same lens that was named Super-Takumar in 1962. The Auto/Manual switch was also reversed, with the red M to the right.
The serial number on the lens in question, 839596?, corresponds to my Super-Takumar 55/1,8 (839265) from 1962. My original reversed Auto-Takumar from 1960 has serial number 374466.

There were at least 4 variants of the Super-Takumar 55/2. The early first version had the reversed aperture ring, the late first version had the standard aperture ring with F2 on the right. 1962 would be right for the early model 1.

QuoteQuote:
2: Super-Takumar 55mm F2 (model 1 early), aperture ring has fine ribs F2 to the left
3: Super-Takumar 55mm F2 (model 1 late), aperture ring has fine ribs and F2 to the right
4: Super-Takumar 55mm F2 (model 2 early), aperture ring has coarse ribs
5: Super-Takumar 55mm F2 (model 2 late), aperture ring has coarse ribs, lens supports open aperture metering

Can I not use it on a Nikon FX? There are m42-to-f mount adapters available...

The focal flange distance of the M42 mount is shorter than that of F mount. So adapters need to have a corrective element to maintain infinity focus. This makes them a short tele-converter.

But only using for portraits, shouldn't matter if there's no corrective element? Thanks

Why not use it on a Pentax ? That is, after all, what it was designed for.

If it will focus, it will work. Aperture will be manual, of course.

Dear mrjayviper,
You have asked for help and assistance concerning your Nikon house and two Takumar M42 lenses. (Included the other thread about the 105/2,8.)
You are advised to either get a Nikon lens for your Nikon house or a Pentax house for your Pentax lenses, as your present combos aren't ideal, to say the least. But as the quoting shows, you will go your own way. Fine.
I can only wish you Happy shooting!
If you are not happy with the result, then welcome back for more help! There are lot of members here with a lot of knowledge, as you may have experienced.
