I have a 70-200 F4L IS anybody know if the Canon 2x extender version 1 will work with my current 70-200 F4L lens , I am especially concern if the image stabliser will work , appreciate your kind advice.
Yup, but it's really not recommended. At the most, the 1.4x should be used on zooms, unless you have a 2.8IS and are really on a budget, yet still need 400mm.
