Are 1.4 and 2x canon extender compatible with leica lenses? In the previous posts I've seen excellent images of 180 apo combined to the canon 2x extender. But with other lenses, and in particular the 80-200? Canon extenders protrude to lens ~10mm, so lenses like 80-200 are definitely out of the question.
I don't think there's anything in the mount of the Telyt-R 400/5.6 that would preclude using either of the Canon extenders. The combination would be slow, but it's a well-respected lens in your price range. I don't think either version of the 250/4s or the 350/4.8 will allow for the extenders, but they can be found for $900 or less. The rest that will work will more than double your budget.
If you really like the idea of getting a Leica tele, then why not consider either the 250/4 or 350/4.8 and then picking up a 2x APO extender later? It's a vast improvement over the original 2x.
