An overlooked repro/enlarger lens, made by Agfa, but actually was designed by Staeble, which Agfa had bought.

Thank you for your valuable insight Klaus.

Most welcome! Forgot to add that it is a HELIAR design (most likely).

@Kath: What a very interesting lens you got.

Just curious, you use a bellow due it's longer register distance or because it's the practical way to mount the lens (and act as macro lens) ? ...

I like the colors, I mean in general. Every picture you have posted shows awesome colors. I think it's partially the camera's merit, Sony Alpha (and I want to point out "alpha", as I can't say the same about my nex-5) has great colors usually, but I wonder if you apply any PP to your photos, thx and I apologize for the offtop Razz

Yes on all fronts. To give it the most versatility while sacrificing very little. Very Happy

I think variables like light, angle of light , and settings used are also very important factors. I use a version of Lightroom to import my photos and always tweak it a little when necessary. I try not to overindulge in what you call PP, but am always striving to get the best outcome.
I have seen some amazing images from the Sony Nex on the web and "Uhoh" a member here puts out some pretty good stuff from his Nex. I cannot say much there as I myself have not used the Nex. Very Happy

I think there is a subforum where the "comparers" compare them.

Best y'all

Ian, I think a link would have sufficed- your images are not relevant to the title. I hope you are sensitive to that.

Not everyone has your sensitivity and politeness Kathmandu Wink

Sorry, Kathmandu, I have deleted my post.

Cheers Klaus, I really appreciate the jibe at me.

That's sarcasm by the way, I don't appreciate it at all, very rude indeed, shame on you.

No problem, sorry for intrusion. I really like your samples btw, I have seen a few of these Eskofot lenses on ebay, never thought to try one.

No problem ! and thanks-I am always open in trying older lenses like this -lenses not have sample images visible through "search". I read a little in the LF forums ,nothing conclusive, and no samples.
Klaus was resourceful enough to give me the design/make to the best of his knowledge/experience.

Having used it a little- I have yet to try its "closeup-macro" potential. I would like to see what kind of image quality I'd get with a hood on this lens.

Adios ababa

I have got precisely the same lens, with another producer name. The inscription on the barrel states Staeble-Ultragon.

After a fast and a bit ackward custom adaptation I may test it for distant shots. The results are not as impressive as the ones by Kathmandu. I presume the lens will improve greatly with a hood. Otherwise its contrast seem low and colors dull. Still, the net and sharp lines are what you have from at f8 which is the lens' wide open.

#3


All images are auto-adjusted. The camera is NEX-5N.

An original shot without corrections (and no hood), to give an idea.

And here comes the info of the lens' optic design:

"Those Staeble Ultragons are symmetric Plasmat constructions like Schneiders G-Claron. The Staeble Ultragon was also sold as “Eskofot Ultragon” and “Agfa Repromaster” (Agfa owned Staeble since 1969)." (Source)

I had one, Klaus. 6/4 plasmat type.

I could be mistaken, but AFAIK there've been only two, perhaps three, heliar type process lenses. Voigtlaender Apo-Skopar (not a tessar type, in spite of the name) and Boyer Apo-Saphir (most, the very earliest were 6/4 plasmat types). The VM is vague about TTH's f/9 Butal,suggests that it might be a heliar type.

I have 7 or 8 of these Staeble/Agfa lenses in lengths from 80 to 270mm, all of them are 6/4 plasmats and very fine ones too, however, the pale blue coating is not the best. I use a 4.5/107 on a helicoid on my Sony a850, mostly for macro work and it is extremely sharp but low contrast which needs to be fixed in PP.
