Name this lens

Hi all,

I found this lens,
Carl Zeiss Planitar 4.5/180.

I am trying to find out what it is from, and if it could be used as a finder or whatever.

Thanks

Some kind of weird macro or reproduction lens, maybe. Check out this link:

This was the most useful link from a search on google for Zeiss Planitar. There is one hit on google for a german forum where someone asks the same question you did, but there are no answers. Here is the machine translated link:

Hi Alan
You might try looking at the Rolliflex camera line. They used the Zeiss Planitar lens and from the numbers it might be an F4.5 180fl but I have no idea which camera or product line it might be from.
Hope this helps
