That may mean that the 8 element lens was replaced with the 7 elements before the SMC coating came into production.

The 8-element lens was only produced for 1 year, 1964. SMC coating came into production in 1971...

Boris, the catalog I have shows the SMC, the Superlite 2 Flash and the Spotmeter 3 (1/21 degrees) .
The catalog does not include the cameras but a Spotmatic ( maybe an F ?) is shown on the front cover
Would you be able to put a date on my catalog?
Thanks

S-M-C or SMC? The SMC versions came out in 1973 along with the F.

Catalog shows 'SMC" all through

Then it's probably 1973-1975.

Thank you.

It's a Super Multi Coated Tak, I understand the S-M-C is a completely different version. Is that right? and What is the difference between this one here, a Super Tak, the Super Multi Coated and the S-M-C Tak's on the 50mm f/1.4 flavor? Thanks

S-M-C says Super-Multi-Coated on the front and has a knurled metal focus ring

SMC says SMC on the front and has a rubberized focus ring

All 50/1.4 Takumars with the SMC coating are 7 element lenses along with the vast majority of non-SMC ST 50/1.4.

For those interested in the history,
The 7 element Asahi Takumar 50mm f/1.4 may be a modified symmetrical lens based on the Speed-Panchro movie lenses invented in the 1920's for sharp, wide aperture use . It might have followed an early Leitz Summarit The son of this lens might be the 7 element SMC Pentax -M 50mm f/1.4.
My reference is Arthur Cox , Page 247, also Diagram S52 and the service manual for Super Takumar 1:1.4 50mm and an undated Pentax catalog showing a diagram of the -M 50mm f/1.4.
I am not expert on all this but I am presently "repurposing and rebuilding " a process camera which has an old Ilex lens also based on the Speed Panchro.

my 8 element has a serial # 1335309 and the IR mark is to the right of the "4". It also has a protruding rear element which when you focus to infinity sticks out a little behind the end of the screwmount. also I believe that the 8 element doesn't yellow because it didn't have the radioactive glass..i read that somewhere and it could be wrong so dont take my word for it

I have a very close serial number lens at 1357236 which I believer is an 8 element. The switch is labeled A and M not Auto and Manual. There is no white dot between the 1.4 and 2 aperture marks. There is a mark to the right of the 4 in a similar spacing to the red IR mark I've seen in the other photos (the red IR line to the left of the 7 element has a larger gap). However, this line on my lens is very clearly white.

Has anyone else seen this?

There is a discussion on the 8-element Tak in the lens review section.
