Doesn't work at all.
For a 2X converter, you will lose 2 stops, not one. Only the 1.4 will give you F4 on a F2.8 lens...
Terrible idea. Real possibility of accidentally zooming to 24 and breaking the rear element of the lens and/or the front element of the TC. Nikon prevents their TCs from being used with th 24-70, and while it can physically mount the Kenko TC, Kenko does not list it as compatible.

Thank you for the clarification and edification, Gene.

When you use it on a smaller sensor, only the middle of the lens is used, and this lens can have decent center sharpness. It does not have good contrast at any aperture, distance or focal length, the flare can be awful, and I don't think I have ever used a lens with that much CA.
I agree on all of the above. Once again you've proven yourself a trusted resource.
