Hi All,
It is my observation that third party lens makers would often mark the mount (usually in red letters) with a code for the type of lens mount a particular lens is. These vary somewhat between makers but many of those are easy to decode.
Example:
SR or M/SR or MD or M/MD = Minolta
But occasionally I come across a lens marking of which I am not sure what it is. For example I am looking at a Soligor lens with a T4 mount that is marked with "SL" (and yes, this does have the T4 mount installed). The eBay listing claims it is for Canon which considering the date of the lens would make it FD, but I suspect that might be a mistake.
Or another example, I believe "U" is sometimes used for M42?
Question is this:
Does anyone know of a reference list of such lens markings?
I could imagine a table with various third party lens makers as the column headers and the various lens mounts as the rows, and each cell contains the lens marking(s) for that combination.
Regards, C. |

I've found this page useful, on occasion https://wycameras.com/blogs/news/35mm-slr-lens-mount-identification-guide-1 … no letter codes, per se, but plenty of good detailed pictures.

"U" is for 'universal' (I believe), from the days when M42 lenses were widely used by different manufacturers … Pentax, Praktica, Edixa, Fujica, Ricoh, Zenit and many more brands, if not actual manufacturers, sold M42-mount SLR cameras from the '50's well into the '70's. |

That link is ok, just missing a good number of mounts and yet another photography lens mount mount ID page with pictures that have blown highlights that makes identifying features impossible... Awesome job photographer, well, at least the pictures were in focus and not full of noise.

Hi Dave,
Very interesting list, thank you. Interesting to note that "C-AF" was used for Canon's FL mount. Back in the early 1970's they could not have foreseen that one day "AF" would suggest "Auto Focus".
Regards, C. |

You're welcome. Yes – there's plenty of room for confusion with some of these old designations. This isn't helped by manufacturers re-using names willy-nilly such as Canon EF (a manual focus camera and auto focus lenses), EF-M (a manual focus camera and mirrorless lenses), R (a mirrorless camera and manual focus lenses), etc. It certainly doesn't make internet searching any easier... 
Here's a similar list for Komura Intermount (the final system from this manufacturer with auto diaphragm and meter coupling):
Canon FD: "C" or "CFb"
Contax/Yashica AE: "CY"
Fujica ST/AZ (M42): "F"
Konica AR: "T3" (usually matched to lens)
Minolta MD: "XD"
Nikon pre-AI: "NF"
Nikon AI: "AI"
Olympus OM: "OM"
Pentax ES/SPF (M42): "ES"
Pentax K: "PK"
Rollei/Voigtlander QBM II: "RF"
Strangely there doesn't seem to have been a vanilla M42 screw mount – only the Fujica and Pentax variants. Also, with some other systems such as Tamron Adaptall there is a difference between the Canon FD and FTb mounts, which doesn't appear to be the case here.

Great!
I am trying to create a spreadsheet with all of this info. Long way to go yet, but perhaps at some point recognizing these codes on lens mounts might be a bit easier.

Have yet to personally see a "NF" mark for Nikon F mount. "F" seems to be the norm of what I come across.
"N/AI" is the most common for AI. I have a vivitar here marked AI/S in red, without an "N"...

I'm pretty sure that despite the longer tab they are totally compatible with PK - at least till AF comes along (the screw drive for AF catches in the connection for the 'Ricoh pin' |
