Hey everyone,
i was wondering if someone could tell me how to find out when my lens was made. i've been searching all over the place, and i can't seem to find much information on it. it's a super-takumar, and the serial number is 288xxxx.
Any help would be great, thanks!

Unfortunately, Takumars cannot be dated by the serial numbers. But I'd say your serial number comes from the second half of the 60's.

Hi.

No doubts that your lens is the 7 elements version

This lens was made from 1965 to 1971.

Take the lens and see:

If the lens has not a white point at the place of F/2 in the aperture ring, it was made from 1965 till october 1966.

If it has the white point, was made from november 1966. Inside this class, if the N° of product is 37801 the lens was made till march 1969, If the N° of product is 37802 was made from april 1969 till 1971.

Good luck and, sure, very good pics.

Rino.

Just a quick fyi about the "M42x1 Standard Takumar lenses for Asahi Pentax cameras" chart. It marks the s-m-c takumar 1.4/50 as the same weight as the super takumar which is incorrect. My three s-m-c came up within a 0.5th of a gram of 255 exactly, much closer to how the smc is marked. This is, to my understanding, because the back element was redesigned and made thicker. They may be the same lens scheme, but they are of different designs.

Also if you have IR mark on the DOF scale inside F4.0 it's 8 lens version, if outside it's 7 lens version.

if that's true then it's definitely 7 elements

Look at the A-M switch lever. On the rear side, nearest to the camera, there should be a stamped number. (Some lenses don't have this number but most do). This is the Asahi part number listed on the chart I linked to earlier. Your lens should be stamped either 358, 378 or 37801 according to the chart. However my lens is stamped 37800 Confused

The Pentax (old takumars) lenses have not the deepnes studies that have the Zeiss or Leica lenses.

Note that the Super Takumar, first version with 8 element, the second version of 7 element, and the S-M-C and SMC are three different lenses, and that isn't said.

All the 7 elements 1,4s are considered like an only one schame, while there isn't true.

The collector face of the photography has a lot things to know. And the user curiosity too.

The best page of takumar lenses have to be done yet.

Thanks for this info - Mine has the mark inside the 4's. SN: 148xxxx

At mine, there is also a "2" instead of a spot between f1.4 and f2.8,
as seen here: http://www.flickr.com/photos/jeffk42/2590397175/
I don't know if that's a major difference, too?!

Plus, there is no numbering near the A-M switch.

Best regards
