Re: 1.4x Teleconvertor, Canon vs Kenko

Hi,

I believe that I know what the DGX-E is designed to do. With the DGX versions certain lens will not function in combination with the Kenko DGX models if you have per lens microfocusadjustment  turned on with the following Canon Cameras 4d3, 1DX, 6d, and 70D. The lenses that won't funcition in that situation include the 100-400L and 300 F4IS L.

I sent my kenko lens into Kenko and after their testing was sent a refund because of that issue. There are work arounds (turn off per lens microfocusadjustment before mounting the lens t-con combination). At the time support told me they didn't have a converter that solved the problem. I suspect the new DGX-E versions are designed to address that issue.
