I have a Nikon d7000 and a Nikon 300mm f4. What would be a good choice for this ?
As it is, it is a 450mm. What would I get with a 2x ?
Any idea's would be welcome.

You get a 900 with a soft center, less sharp.

I’d try the 1.4x first. You should still be able to autofocus, which you’d lose with the 2x.

The 300mm is remains 300mm whatever sensor you put it on , it just the field of view that is effected.
I have used both the 1.4 and 2x . 1.4 is great wit, what seems to be, very little loss but the 2x just gives so much loss that it hurts. However , better that must be better than having no photo.
Hammer is correct. I've had that combo. The lens still works very well and stays sharp with the 1.4. The 2x will show less sharpness (unacceptable in my book.)
You also need to autofocus fine tune with each teleconverter. That should help some.

......IMO, you are better served using a 1.4X and maximizing your IQ and CROPPING and use well applied pixel enlargement software if need be.

Depends on which 300 f4 your talking about, for the older one, you cannot use the TC-14E III, the newer version can handle the TC-14EIII.
As far as using the 2X, they both have AF limitations with the 2X. Auto focus is available only with cameras that offer F8 support. The D7000 does not have this, so, no, you cannot use the 2X and get auto focus. You can do MANUAL focus.
I have the 300 AFS F4 and the TC 1.4 II for BIF, wildlife. Most of the time, very minimal impact on overall performance and IQ. Good combo. I have tried the 2x. Not usable.
An effective F8 aperture (2 stops loss of light)

A 2X teleconverter gives you an f8 lens of marginal image quality. Save up for a 600mm.

With a 2x you'd get 600mm, with would have a field of view equivalent to 900mm.
I am guessing that when Nikon designed this it was for their fastest and sharpest telephoto lenses - like the 200 F2, the 300mm and 400mm F2.8 - all of which are uncannily sharp. With a 2X TC the uncanniness goes away, making them just average-ly sharp lenses.
Besides your D7000 will likely have issues auto focusing which means you'd have to manually focus, and this is pretty hard to do when you through a viewfinder with an F8 lens attached.
If you need 600mm on a budget, you really can't go wrong with the Tamron 150-600 G2. I've got a friend with that exact combination and her stuff is quite good.
