Hi Shawn,
yes, it's the same 'Vivitar Automatic Tele Converter 2x21' (whatever the
21 stands for?). I like the idea of converting a converter. Please tell,
if there is a problem with vignetting in the developed slides or
negatives. Then, the ultimate solution might be to drill up or file open
the black plate a bit. There is lots of room for that. Thanks for the
info.
Cheers,
Soenke, Hamburg
