Please help identify Carl Zeiss Jena f2.8 Macro

[heard86]

Please help me identify this lens. As you might be able to see from the picture that it is missing the plastic ring that normally contains the name of the lens. (does this affect the photographic qualities of the lens or is it purely cosmetic??)





Also any info on the value of it would be much appreciated.

Thanks

Below is the mount which looks like a screw thread

Kind of a crazy price for a Japanese 28mm lens if you ask me :S

Thanks for such a quick reply. Does anyone know if the fact that it is missing the plastic ring that contains the lens info,if this has an effect on the lens or if it is just cosmetic?

Thanks

Made by Cosina I think.

[Attila]

It has no value , bring only name of Carl Zeiss Jena nothing else, go for 20% higher than other noname Japanese lens in same focal length in normal case. Who made it really no matter , several low quality not respected brand like Sigma sold as Jena lens.

[heard86]

looking at the "m" and "ft" values, it seems like this is a different lens...

[iangreenhalgh1]

They were made by Sigma and Cosina, not sure if any others also made them. You are right, they are pretty low quality, they represent the cheapest Japanese production of the late 80s/early 90s.

I think this one is this Cosina rebadged:



If it's like other Cosinas of the same age I've tried it will be so-so in sharpness, muted colours and so-so contrast.

[heard86]

Thanks so much for the replies...

I intend on selling it so If somebody could help me find the exact specs of the lens it would be a great help....

It seems a lot more like this one than the other ones you have posted about:

http://www.mflenses.com/carl-zeiss-jena-ii-28mm-f28-macro-japanse-version.html

It has a "P" symbol on the rear lens cap.

Can you work out the exact spec from the numbers on the side?

Thanks

No bid history, sold on fixed price , probably for clue less beginner or to seller friend and they both agree to cancel transaction. In this case Ebay refund fee. Sold item will be a good reference as market price and next time real buyer will happily take for half price 80 UKP a 20 ukp value lens. Obvious trick and works.

[iangreenhalgh1]

There's no Cosina 2.8/50s on ebay UK, but the common Cosina 2/50 in Pentax K mount is a 5-10ukp item.

Here's a similar 'Carl Zeiss' lens with caps and original leather case with 3 days left, this might give some idea of value by it's final sale price:

[iangreenhalgh1]

No, the Japanese 'Carl Zeiss' lenses by Cosina always came with those brown leather cases, that was the best thing about them.

[Lightshow]

looks like the 24/2.8 version, not the 28/2.8

[Pancolart]

The discussed 2.8/24mm Cosina gives quite decent results. Mine was branded Exaktar. I doubt Cosina marketing would be so stupid and not use Zeiss brand name on their good product. Here some old shots: http://forum.mflenses.com/cosina-macro-2-8-24mm-on-pentax-k10d-a-bit-of-neo-noir-t54193.html
