As I am currently stuck in the house with the flu I have been killing time browsing the internet and indulging my LBA on ebay. I came across a Carl Zeiss Jena Jenazoom super 28-70mm f/3.5-4.5 in pentax AF mount. It says it is made under licence from Carl Zeiss in Japan but does not say who by. I ran a couple of google searches but couldn't really find much about it. I found a refernce to a CZJ Jenazoom 70-200 which was believed to have been made under licence by Sigma. As it was going cheep I put in a bid and to my surprise got it for £5. I really don't need it but at that price I didn't think I could go wrong.
Hopefully it will arrive by the end of the week so I can have a play but in the mean time does anyone know anything about this lens? Details given in the listing are here:

It was made by Cosina...I don't know how good it is...but you will soon find out.

The lens turned up already

. It may not have been made in west Germany but the build quality is certainly consistent with Zeiss

. It is almost all made from metal, the zoom is smoth and the auto focus quick. The only down side of the lens that I have found so far is that there is no focus ring - auto focus only. I haven't really found out how good it is optically yet, but initial impressions are that it is comperable to my FA 28-105 power zoom. I will post some photos once I have something worthwhile. Got to be the best £5 I have spent in a long time
