Voigtländer Tele-Dynar Information...

[ELDAR]

I understand that the Voigtländer Heliar design was originally called the "Dynar" and only later changed to "Heliar". I have searched and found and absolutely no information on the Voigtländer "Tele-Dynar". I've seen an uncoated 25cm and 29cm version in a Compur shutter. Is it, in fact, of the same design as a Heliar? Does it share similar performance characteristics in terms of bokeh and sharp to soft rendition? Any and all information will be greatly appreciated. Thank you.

ehhhmmmmm...

The Heliar was first, I believe. Then came the Dynar and the Oxyn. And then a Dynar-type lens was sold as Heliar, while the Heliar design lived on in the "Universal Heliar".

The Tele-Dynar seems to be "variable": Some are 4 in 3 like some Tele-Xenars, while others seem to be 5 in 3 - rather like a Dynar, but with different curvatures and spacing. I haven't used one myself, but I would assume the design criteria would be different from those of the Dynar/Heliar.
