Carl zeiss jena ii

Is this lens worth buying ? CARL ZEISS JENA II F=28MM 1:2.8MC MACRO 49. Will it work on my D5100 ? I don't mind full manual ! Any comments !

I forgot to say I will upgrade to full frame at some time !

If your looking at the one that's on eBay at the moment, then no, it looks to be to be a Canon FD mount

Thanks for that

Zeiss lenses are all manual focus for Nikon and Canon mount. .zf has the chip included so that it will show the exif data.
