B4 Mount Lens Question

Im looking at getting a B4 lens for the AF101 with 2 x extender, I am aware that you have to use the extender and also the light loss but my question is do the lenses have to be made for widescreen cams? I ask as there are quite a few older B4 mount lenses around and some coming of older 4:3 cams, may seem a dumb question but does it matter?

I assume you are asking if SD lenses will vignette. No, they won't. The Canon J series and the Fujinon A series, with 2x extender, will work fine.
 
I had an older Fujinon 5.5-47 BEVM wide angle that was made before 16x9 became the norm and even with the doubler it vignettes. So test before you buy if you can.

I was surprisingly pleased with the results I got with the Canon j21. I had concerns that using a non-hd lens on this cam would be suspect. Not at all. Very nice detail, sharp and warm.
