Does anyone know if the CZJ 70-210 any good? I just bought one of these but wasn't able to find any info on the internet.... Hopefully it won't be too bad as I gave up the money for Pentax SMC A 70-210 to go for this CZJ.... Thanks. Crying or Very sad Crying or Very sad

I never heard of any Carl Zeiss Jena zoom lens.
I know of the Carl Zeiss Oberkochen 70/210 f/3.5, a very expensive lens, and of the Prakticar 70/210 f/4-5.6, obviously much cheaper.

Do you have a couple of clear fotos of this lens?

I guess this CZJ and Prakticar may be the same lens... Praktica-users.com site says the Prakticar is a Sigma rebranded lens.

don't have photo on hand, but it has a blue line around the rim of the lens. I will try to find one and upload

If the info provided is correct, this supposed CZJ lens is one full stop faster than the Prakticar. So it could not be the same lens.

I too thought about the possibility of a Sigma lens - the focal range 70-210 is typically Sigmish.

...or its made by Cosina (Carl Zeiss Jena not Carl Zeiss later Z series lenses) and may be in this case, a rebranded Cosina/Vivitar Series 1 70-210 f:2.8/4.
See here the 4th and 5th versions

What filter thread it has ? 58 or 62mm ? You CZJ has a similar construction/design ?
http://www.robertstech.com/pages/viv_02.htm - from the same lens and site.
Another one:
Click here to see on Ebay

It seems that it was made an AF version too.

Yes, you're right Cosmin.
It looks like one of those Japanese Jena-wannabes
But - like Attila said - this does not mean necessarily it's a bad lens. Sloven you will find out by yourself trying it. If you don't like it, you can always sell it and buy something else. So no problem.
