I am getting interested in getting a 50/4 macro pre-set!
Mine is all black.

Andreas, I remember old Pentax ads from the 1970s that showed cutaways of their lenses, to reveal the mechanical superiority of the product. They explained that focusing helicoids of aluminum on brass were naturally lubricated and required no other lubricant. I believe Minolta Rokkor lenses until the late 1970s had such construction, as well. (Then they started making lighter, more compact electronic cameras and smaller, lighter lenses to go with them.)
Interestingly (to me, at least), until multi-coating, Minolta had what they called "achromatic coating," which was dual-coating. This gave Minolta an advantage over others until Pentax came out with Super Multi-Coating (7 layers) and Fuji came out with their EBC (Electron Beam Coating: 11 layers!).
Thanks for keeping this thread going, Andreas!

thank you Murray for your more detailed knowledge!!
I believe, just a theory but it often is said that at least late Super Takumars already had several layers of coating, that Takumars already had several layers of coating before they started to call them Super Multi Coated. Add / or that their early, even if it were single coated lenses, had comparatively good coating.
Andreas, you may well be right about the coating on Super Takumars. I have no knowledge about that.
Multi-Coating is nice, but I have a lot of older lenses that don't have it and it has never really been a problem. I always use lens hoods though.

According to this article from Asahi Optical Historical Club's website, Asahi Optical Co. Asahi didn’t invent the multicoating, since it bought the patents from Optical Coatings Laboratories Inc. (OCLI), based in California. Other Japanese manufacturers had to pay royalties to Asahi Opt. Co. in order to use the multicoating process. Zeiss did maybe benefit from the cooperation it had with Asahi Opt. Co. at that time and was indeed one of the first manufacturers to offer lenses using its T* multicoating process, which was very similar to AOCo's Super-Multi-Coating.thank you Murray for your more detailed knowledge!!

oh, interesting and..beautiful 😉
I believe my preset Takumar f3.5/200mm came with an all black cap that looks like yours. ( My Auto Takumar f1.8/85, the lens you show, unfortunately came without front cap. )
There are also all silver Takumar caps as e.g. that of the Auto Takumar f2.3/35mm, but they don't say Takumar but AOCo ( for Asahi Optical Company )
Takumar lens caps with black body and silver writing that says "Takumar", as seen on my earlier photo, also came with some early Takumars only and therefore now are rather rare. Later Takumar lens caps look similar, also black body with silver writing and fully metal but their lettering say "Asahi Pentax". These are the most common Takumar front lens caps.

The article also supports Kuuan's above theory by stating that "late production Super-Takumars were already multi-coated. It was probably just an experimental coating, maybe less than 7-layers, or maybe it was not on all air-to-glass surfaces, so that it didn’t perform as well as the definitive Super-Multi-Coating".

I have an AOC cap for my Auto-Takumar 135/3.5, and another orphan larger-diameter one that I suppose would be for the 35/2.3. Also several "Honeywell Pentax" caps, and a couple "Heiland Pentax" caps. I suppose that one could build quite a collection of Takumar lens caps.
Honeywell, the importer of Pentax photography gear to the USA until the late 70s! Greyscale of course! They had put their own name on cameras and ..caps, also that of Heiland, a manufacturer they had bought.
All my Takumars I had bought either in Europe or Japan, no Honeywell or Heiland there. Made me not think of it, sorry. Thank you for adding that!
I believe that Honeywell was a originally a subsidiary of Heiland Research. The Heiland-branded cameras are earlier than the Honeywell versions, I think only the H1 and (maybe) the H2 were the only ones marked with the Heiland brand. Most of my Pentax screw-mount cameras are Honeywell Pentax. I don't know if any of the K-mount cameras carried the Honeywell branding.
You're welcome, Murray!Great information, Abbazz! Thanks!
Thanks, Andreas, I really appreciate your kind words. And please keep on posting your wonderful Takumar pictures!thank you so much Abbazz for this article!! You are much needed here!

almost now Takumars I have left to show, there are a few, but embarrassingly I hardly have taken photos with them
the S-M-C Takumar f1.8/85mm

so far only have used it to take "portraits" of a few other lenses
RE-Auto Topcor f1.8/58mm

MC-Rokkor f2.8/24mm

used lens wide open but did "focus stacking" to get the whole lens sharp but max. blur of the background
