Zeiss-Jena 500 f5.6 M-42

Has anyone tried this lens on a *ist-DS or newer Pentax DSLR? I assume (!) that the more-or-less standard M42-to-K-mount adapter would be necessary and workable.

I'm not really up on my Zeiss history but I seem to recall hearing that Carl Zeiss Jena's postwar products were inferior to the West German Zeiss items. Truth or jingoism?

Anyway, this lens is on ebay right now at $200 with 5 days to go. I'm inclined to pay up to maybe $400 or $500 for it. Any opinions?

Sig

I have the Carl Zeiss Jena Sonnar 200 mm f/2.8, and it's among my 3 best lenses.
I don't use it all that often, mostly due to it's size, and weight. However it has excellent optics.

I would at least hope that the 500mm f5.6 version does as well.

You will want to use a tripod whenever your using that lens, and try getting someone else to carry it for you

Is it really a Zeiss? None of the photos show the Zeiss name.

I would be curious about this lens, item# 150297589221.

Are you blind? It says "Carl Zeiss Jena" right on the front of the lens..

btw, it's F/5.6 - F/8

Two different lenses here; The OP is referring to a Pentacon fixed focal length lens; the Flee-bay item# 150297589221 is a Zeiss-Jena zoom.

When is a CZJ not a CZJ?

Guys-

Sorry, I'm so confoosed.

The Ebay vendor called the lens, item number 220285825714, a Zeiss Prakticar Pentacon. A member here said it's really something else. Does this mean that it's really made by another company and labeled as CZJ? Or that the vendor is calling it a CZJ but it hain't?

Hello Sig,
there you go,

Meyer Orestegor / Pentacon / Prakticar 5.6/500

http://forum.manualfocus.org/viewtopic.php?id=5752

Meyer Görlitz have at some point become Pentacon (lens-label-wise). Both of these have never been CZJ. Lens-label-wise it's quite easy: Any CZJ lens either bears the engraving: 'Carl Zeiss Jena' or 'aus Jena' or simply 'Jena'. So you would always find at least the 'Jena' engraving on any given CZJ lens as a guideline. You will not find any 'Jena' engraving on a non-CZJ-lens and vice versa.

From CZJ I would recommend the 2.8/180 Sonnar, the 2.8/200 like little laker suggested, and the Sonnar 4/300 M42-version (not the Prakticar). The latter lens I do not know but see the lens scheme and expect a bigger 180, which seems to be the reference in east german teles. The middle format people rave about the 180 and the 300 Sonnar, which both need a P6 to M42 adapter.

I would not even pay 200 dollars for the lens you are looking for, cause I don't expect anything from it, compared to modern lenses with better coatings and much better correction and above all portability. In this league (read: big and heavy) I'd recommend the Tair-3 photo sniper lens, which is an M42 MC 300/4.5. It is best sharp at 5.6 and should cost you not more than say 60,- US-$. I do not really have a decent tripod for this beast, and can only imagine what a monster tripod and head you would need for this Pentacon lens.

Hope I did not disappoint you too much, but there is always another lens and there's no cure for this anyway :-)
Best, Georg (the other)

Thanks for your input

All:

I appreciate your comments. This is why I joined the forum!

I currently use a Sigma 400mm f5.6 (early, green, non-APO, I believe) usually with a generic 2X Japanese teleconverter, to photograph osprey that nest high on light poles on a football field near my home in Maryland, U.S.A.

Your comments, along with the fact that the Practikar is only a f5.6, have disuaded me from bidding on it.

Big and heavy don't scare me (much) but the cost of modern lenses of equivalent speed/focal length puts them out of the question. For example, the Sigma 500 f4.5 hits the streets close to $5000 US! If I can get an SMC Takumar or PKA for $500 or so, I'd be willing to put up with the length and bulk.
