Re: Kenko Teleconverters....

I have the 1.4DG and it correctly reports my Nikon 300mm f/4 as 420mm f5.6, but my Tamron 90mm f2.8 stays 90mm f2.8 with the TC on. I think the DGX is supposed to correct this on all lenses.

I found this on Amazon:

The main difference between DG and DGX is DG doesn't correct aperture of the lens and DGX does. For example, Tamron 70-200mm has wide open f2.8 aperture that reduces to f4.0 when used with 1.4x teleconverter. DG version would still show you f2.8 and new DGX will display correct number f4.0. Otherwise, both DG and DGX models are the same.

I'm unsure about this as I think (I have to double-check) my DG shows the correct aperture and FL used to capture an image. I use NIkon View NX2 to view image data.
