One, A(n) Asahi Opt. Co. SMC Takumar 55mm. f/1.8,
(looks like it was submerged in wheat flour).
With serial number: 54839XX.
The other one, a Panagor PMC Auto Wide Angle
28mm. f/2.5.
With Serial number: 683XX
Is any of these lenses any sharp? Is the latter one
a 35mm lens? I had never heard of it. Is there a
good place to send the first one to clean it from
its 'flour-bath' ?
Asahi Opt. Co. is the name of the company that became Pentax, with the K-mount (now owned by Ricoh). SMC is Super-Multi Coated (one of the best). The SMC Takumar 55mm f/1.8 is the lower-end normal lens, compared to the SMC Takumar 50/1.4, which I own. They're both fine lenses.
These Takumars are M42 screw-mount lenses. The SMC Takumar 55/1.8 was introduced in 1973. See the AOHC site for more info. It's pretty slow.
I expect it would be less expensive to buy another Takumar, than to pay to have it cleaned. Looks like they're going for $65 US or so in Mint-ish condition, including shipping, on eBay.
Panagor is a 'third-party' brand. You might find out more at this and similar sites:
If it's true that Panagor is a brand for lenses made by Kino, then its probably worth about $50 to $75 US (based on current eBay sales of the Kiron 28/2), depending on what lens mount it has. You can research vintage lens mounts at these two sites, that both appear to be offline ATM. You might find them in the Way Back Machine.
I used to own and shoot with almost all SMC screw mt Takumars...from their groundbreaking 15mm f3.5 rectilinear lens they co-developed with Zeiss, up to their 500mm f4.5 lens. They also had a 1000mm lens which I didn't own but owned and used some special purpose lens like their 17mm f4 circular fisheye.
Initially when Pentax moved over to their K mount bayonet lenses, most of these SMC screw Mt takumars were re-issued in K mount. Eventually the offerings of Pentax K mount lenses expanded.
I still have a few common SMC Takumars and I should use an adaptor and try them out on one of the Leica mirrorless cameras. Many were extremely fine performers, especially in their day.
To answer your question - no - not worth the cost of CLA unless you are able to do it yourself. Even then, there are hundreds of sub-performance lenses to play with if you want to play with 50+ year old lenses. Almost everything made today is far, far better.
