Let me start by saying that I am not very familiar with Pentax lenses and the various naming conventions, so excuse my mistakes in that regard.
I am looking at a Pentax 150mm 4.0 in M42 mount. The front ring says: "Asahi Opt. Co. Japan Super-Multi-Coated Takumar" which according to information I have found means it is the third version of this lens, and the last one in M42 mount.
https://lens-db.com/asahi-super-multi-coated-takumar-150mm-f4-1971/
Lens-db describes it as "Mod. M42". Will it work with a standard M42 adapter? The Novoflex adapter I use has a small ledge on the inside that keeps the aperture pin on the lens depressed, although it looks like this lens has a manual/auto switch so that shouldn't be a problem either way. What exactly is the modification to the M42 mount on this lens?
Regards, C. |

Here we have:
1. Super-Takumar 1:4 / 150 -- M42, model I has 5/4 optics, 43740 stamped on Auto/Man switch. Early model I have glued rear dust cover; later model I have threaded rear dust covers.
2. Super-Takumar 1:4 / 150 -- M42, model II has 5/5 optics, 43741 stamped on Auto/Man switch.
3. Super-Multi-Coated TAKUMAR 1:4 / 150 -- M42, 5/5 optics, 43742 stamped on Auto/Man switch.
4. SMC PENTAX 1:4 / 150 -- K-mount, 5/5 optics
The "Mod. M42" probably refers to the addition of the mechanical aperture-position linkage for communicating with Spotmatic ES and F cameras which provide full-aperture metering capability when these lenses are used. The linkage does not prevent usage with other M42 cameras or adapters.

according to Gerjan's book they are both 5/5. Version 2 has different optics in the two rear elements.

 That's what I get for using the first edition of his book instead of the second edition. The first edition does show the correct 5/5 diagram, but typo in specifications list. Thanks for catching!
