Canon teleconverter compatibility
I have a Rebel XT with the EF-S 17-85mm f4-5.6 IS USM lens and will probably
get the new EF 70-200mm f4L IS USM lens when it arrives. Are there any metering or AF compatibility issues between this setup and the canon 1.4x or 2x Extenders? Thanks .. |

If you're buying net-new, I'd suggest a Kenko 300 DG (not the white one), as it supports a greater range of Canon lenses than the actual Canon 1.4! My Kenko works great with my 70-200f4, i consistently get 5.6. |

Both will mate with the 70-200, but only the 1.4x will give you AF, as the camera has an AF lockout for any arrangement over f/5.6. This is one of the reasons a lot of people prefer not to have lenses slower than f/2.8. Mark |
