I won a Carl Zeiss Jena 135/2.8 from ebay not knowing what mount it was. I decided to bid anyway because I got it pretty cheap.

What mount could it be?

I also won this lens from the same seller:

Overall pretty satisfied with the price.

First has Praktica bajonet mount. You can use on olympus 4/3 cameras with a special adapter.

Second is a nice lens I have it.

Thing is I don't have an Olympus. Guess I have to sell it...

Praktica B and Pentax K are almost the same. I have modified a pentax adapter and the praktica fits. I used a pentax to olympus adapter. took it apart and sanded the pentax part. It is a little bit to thick for the praktica, but for the rest it looks the same.

I don't know, is it worth the effort? I might just sell this and buy a Carl Zeiss Jena 135/3.5 instead which I hear is also good.

This is the right solution , 135/3.5 better lens.

It is a CZJ PB-mount one, some like it because of its Bokeh and it was
made by Meyer not CZJ, although its brand name is under CZJ Prakticar.
Optically CZJ 135/3.5 is better one IMHO.

Ah well, bummer... I guess I'll just put it up for sale and hopefully get my money back. At least the other lens fits and is quite good.

Allow me another advice take an M42 version of Pentacon 135mm f2.8 or Meyer 135mm lens as Koji said this lens a bokeh monster , really ,really good one also. I love both.

Thanks for the advice. I've been looking for a Pentacon 135/2.8 the last few days but the ones I've watched have gone a little too expensive for my taste.

Try and make sure you get the Meyer Orestor or the older barrel-shaped pre-set Pentagon version with 15 blade diaphragm. The newer auto version with parallel sides and 6 blade diaphragm is not as nice.
