    Hello Andrey,

    that's something what we don't know for sure.

    The old compensating Leitz Periplans emerged as a counterpart to the Carl Zeiss PK planar and compensating eyepieces.
    They have their continuation in some of the Leica HC, but not across the multitude of the designs in the Leica HC group.
    The Periplan design essentials are also found in some of the later Zeiss microscopy eyepieces, but Zeiss has also several versions of the Abbe orthos for the microscopy.

    The other great eyepieces are the Zeiss (ZEISS West, Carl Zeiss West Germany). The discontinued E-Pl "extra planars", and the real glass aspheric EPs are much sought after, but I am more inclined towards Leitz/Leica.

    Finally, the Periplan design went in the form optimized for the fast refractors into the spotting scope eyepieces of Leica, Swarovski, Zeiss and of others including Kowa, Optolyth, ...
    Herewith the essentials of the old Leitz Periplan design are living further in the spotting refractors. I have all fix focus spotting eyepieces manufactured by Leica, Swarovski, and Zeiss, with an exception of just one I guess, and they are all Periplan derivates. The pics are in my albums. Watching the costs, it took me years to complete the Leica-Swarovski-Zeiss collection. A second hand Leica in top condition costs more than the new Tele Vue Delos.

    The devil must be somewhere in the detail, as the optics design of these eyepieces is easy to understand, and to clone when you have software for "reverse" engineering.

    There are also budget versions of the Leica and Zeiss microscopy eyepieces for metallurgy, college education, and for other less demanding applications, manufactured or assembled in the Singapore plant, and they cost just a fraction of what people pay even for the discontinued eyepieces manufactured in Wetzlar (Leica) or Göttingen (Zeiss).

    Best,

    But then you bought used, not new, correct?

    Yes, nFA I did purchase the GF used in pairs. The HC I bought new from a guy in Israel and it was a little bit less than the TV pan. I did look around for quite a while for that one. But I saw the same eyepiece elsewhere for twice the money. So maybe I just got lucky. My brother used to tell me it's sometimes better to be lucky than good. :-)

    Re: Prices of Leitz, Leica, and Zeiss 2nd hand eyepieces

    Hello all,

    for the Leitz Periplan GF eyepieces and for the Leica HC Plan S, I have typically paid up to 80 USD in Germany, ignoring offers for 250 USD. Now, the prices have increased.
    For the Zeiss E-Pl (made in Germany) I have paid 75 USD in Austria, but I don't know the condition, let's see when the EP will be delivered.

    According to CN, the pre-owned Zeiss E-Pl range in the U.S. and in Japan between 500 and 1.500 USD.
    Some vendors make their living on buying cheap in auctions and surplus sales in Germany, and selling with an insane high profit to the U.S. and Japan. So far identified, these vendors are located in Germany and Spain.

    I am seeing a pair of HC 10x/22 offered by "Hitech", 265 usd for the pair. "Cleaned" and certified by their "technicians" with return gaurantee. That would be 132.50 USD per. These are used . JG is of course correct. The prices can be highly inflated. The new one I found cost me around 225USD. It cost more than used, but I wanted a new one. :-)
    I am still looking for a good price on a 25xGF.

    Hello Mark,

    can't say without seeing it together with the full inscription and original wrap. Some of the Leicas com from Singapore.

    That's more like what I've been seeing.....

    Right now although trying out some of the Leica is interesting priority is to rationalize my set of OTAs and perhaps fill in some gaps in my filter sets.

    I fully understand you, not_Fritz!

    That's why I am keeping the # of OTAs just 2, more of them would take too much of the available space for my hobbies away.
    One 82mm APO for fun-and-more, and one 150mm achro for the faint fuzzies is at the moment enough.

    What I definitely must do, is to consolidate the increasing arsenal of the eyepieces.
    Otherwise, I am more testing the eyepieces than hunting the faint fuzzies.

    Exactly. When I say I'm rationalizing my OTAs it's a matter of aiming to reduce the total number to 4-5 that are not redundant.
