Have you seriously tried it Mike?The reason why I posted this today was that I received the 2x tc this morning and I have sold the Kenko 1.4 but not yet dispatched - I wanted to make sure that I have not made a mistake (mind you I still have a old teleplus 2x that I could try with the 2x and 1.4, that would give me 1680mm 8-P )</blockquote>
