Maybe they designed them in the southern hemisphere.

Eh?
Tell me more.
The markings are correct, the ring turns the opposite direction and the aperture mechanism is mirror image to later versions. I don't believe mine is a Frankenlens or anything like that. I just did a quick Google image search and came up with another without much effort. Another difference from later versions is a click stop at f/13.

Thanks Steve.
So no different in operation, except the twist of the wrist.
Was there any reason?

I have no idea and have no firm information what body it might have been originally sold with either (probably S3/S1, Super S2, or SV). Up until I supplied a photo of my lens, the variant was not in the PF database.

I've got a reverse aperture ring 55mm too. They were intended as the kit lenses for a special edition Spotmatic made for left-handed photographers, with all the main controls on the left side of the camera instead of the right, but it never went into production.

And if you believe that I've got a bridge in Brooklyn I'd like to sell you. . .

The serial numbers on lenses in the first three batches run approximately 765xxx-766xxx, 967xxx-968xxx, 977xxx-978xxx.
Thanks Droo for the incredibly detailed history on the ST50/1.4.

The S/N of my example pictured is 978000. According to your info, would it be correct to assume it is the last one made from the third batch?

My pleasure
You made me get my act together and write something on that model.
Thank you for the SN.
You might have noticed I collect them.

Hi RR84,

Something else about the earlier batches I didn't mention.

According to records the earliest copies have half-stops between all main positions on the aperture ring; and later copies lose both the first and last half-stops viz. between f16-f11 and f2-f1.4. (Later, meaning from about the second or third batch.)
I have one from the third batch like yours that is intermediate between those two states in having lost only one; the F16-f11 half -stop, but it retains the half-stop between f2-f1.4.
Would you kindly check your 978000 to see if any half stops are missing and let me know the result?
Please?
Thank you,
Drop

I don't have the 978000 on hand at the moment, but I do have another from the third batch - a 977***. I checked the aperture ring and it has full stops between f1.4-f2 or f11-f16.

Thank you.
That SN 977xxx would have a diamond at the centre of the DOF gauge and an R next to the IR mark?Cheers

Regarding the position of SN 978000.
It comes from the middle of batch 3 of around 1K copies. My information shows batch 3 runs from around 977483 to approximately 978127 (covering 644 copies ) in a gap of 1114 between adjacent batches of other lenses.

The 977*** has a diamond but no R. It also has the 'narrow' font on the aperture ring, while the 978000 has the 'wide' font (as most early examples seem to have).

Thanks for the information on these early copies of the first Super-Takumar 1.4/50mm.
There is a detailed description (in Japanese) of all the variants recorded for this model at http://http://home.a00.itscom.net/shisan12/index.html if you have the patience.
The tables are self explanatory and you can get Google to translate. It turns out the first three batches contain three different variants A, B and C and so on...

Heavy stuff, I know. But it gets you in.

Thanks again.
Droo
