Mark Deeble Posted January 25, 2009 Share Posted January 25, 2009 Hello I wonder if anyone has had experience with aspherons - specifically either the Zeiss 'Mutar' for the 9.5mm distagon and 10-100mm Vario Sonnnar or the Kern equivalent for the Zeiss 9.5mm and 12mm distagons. I am interested in whether they cover S16? I have a Switar 10mm f1.6 preset which covers but again, don't know whether the 5.5mm aspheron for this lens would cover? Any advice would be great. Thanks Mark Link to comment Share on other sites More sharing options...
David Rakoczy Posted January 25, 2009 Share Posted January 25, 2009 I have a Century Precision Optics - Double Aspheron for Zeiss that covers S16 on a Zeiss Super Speed Distagon 9.5. Link to comment Share on other sites More sharing options...
Jean-Louis Seguin Posted January 26, 2009 Share Posted January 26, 2009 I noticed vignetting on the Switar 10mm with the Kern Aspheron on super-16. Too bad. Jean-Louis Link to comment Share on other sites More sharing options...
Volker Bendt Posted January 28, 2009 Share Posted January 28, 2009 I have a Century Precision Optics - Double Aspheron for Zeiss that covers S16 on a Zeiss Super Speed Distagon 9.5. Zeiss Aspheron with Super Speed Distagon 9,5 and 12mm will both cover S-16, while with the Vario-Sonnar 10-100mm there ist some vignetting. Don't know about the converted 12-120 in 12mm macro setting, probably it should be fine. It's worth testing. Goog luck, Volker Link to comment Share on other sites More sharing options...
Mark Deeble Posted January 28, 2009 Author Share Posted January 28, 2009 Thanks Zeiss aspherons seem very hard to find - but there appears to be a Kern aspheron which fits the Distagons but not the Vario-sonnar which I might try. I will also the test the 5.5 aspheron with the 10mm as by itself, my 10mm covers the 2/3" chip on the s12k which i have been told it is marginally smaller than an S16 frame.

As far as I know, each aspheron is specifically made for a particular type of lens (except of course the aspheron for Zeiss 9 and 12), optically speaking. On top of that, the thread mount is very different on a Switar 10 and on Zeiss 9 or 12, as well as on the Vario-Switar 100 and the Vario-Sonnar 100. So despite the fact that they're all made by Kern, I don't think you can adapt one to another type of lens. I'd like to be wrong about this too, though, as I've thought about getting whichever is cheaper and adapting it too, but... Link to comment Share on other sites More sharing options...
Mark Deeble Posted July 6, 2009 Author Share Posted July 6, 2009 Thanks for all the help. I ended up with a Kern 5.5mm aspheron on the Kern Switar 10mm - which covers well on the 2/3" si2k chip. Link to comment Share on other sites More sharing options...
