I never own a Pentax m42 lens so I cannot help but I suggest adding the following information which may be useful:

a. photos of each lens
b. aperture type(e.g. present, half-stop selection)
c. zoom type: two-touch zoom or push-pull zoom
d. other spec such as build-in hood/filter, movable mount(Sigma YS,Tamron Adaptall)
e. additional information on rebadged lens

Hi Attila,

Updated the Pentax sheet with M37 mount instead of M42 for the Takumar 50/3.5 and 83/1.9, added new lines for the early versions of the 83/1.9 ...

Will check the other lenses tomorrow ...

Cheers

Please click on above link, a Google spreadsheet will come which is editable by anyone, don't need to register. There is several Tabs, like Pentax, Carl Zeiss Jena, Meyer currently , if you know other makers betters please let me know and I prepare it. Pickup one and revise it, lists are incomplete , please fix it. Mark revised line with yellow no matter did you change something or not. When is all line is yellow I know that sheet is ready for import. Many thanks!

All function is done, it shows Canon 5D and 5D2 compatibility with notes.
Image from lens and note from lens. If you filter it for Canon 5D2 you can find an entry Carl Zeiss Jena Flektogon 20mm f2.8 this is line is filled up fully and you can see it. If you see a blue buble with I inside notes are there, move cursor to blue bubble and notes are popping up. Same case on small lens image.

So where do I put an entry if there isn't a tab for the vendor yet?

The first tab says don't edit so I don't know where to add the information.

I would be happy to add stuff, especially my cheapy no name lenses like sunagor and anything else people wouldn't bother wasting their time on lol
