Boy I was hoping it would work with my 70-300. I had checked with Nikon and to date they do not have a TC that will work with that lens. Sigh, maybe the next one.

Highly unlikely. Though it would be nice to have a 1.4x for the 70-300. Nikon won't make a teleconverter for lenses slower than constant f/4.

Hmm an aspherical lens in a teleconverter. Call me crazy but I didn't know anyone who wanted to buy a 2x teleconverter was actually expecting high quality results


lvcrtrs just get the optically excellent Kenko pro 300 teleconverter series. The results definitely won't be too hot since the 70-300 isn't that sharp compared to it's far more expensive counterparts, and that would show up more with a teleconverter.

Also it will be slow or outright fail to autofocus.
