I still haven't decided whether to buy a Sigma zoom that goes to 500mm or get a TC for my 300. I have the ED AF screwdrive version. CPU contacts and AF would be nice, but not necessary, image quality is top priority. Is the TC-300 a good choice? What about the TC14? TC14B? And has anyone had any luck stacking 1.4 and 2x TC's together?

Get the Kenko Pro 300 1.4X converter. I find it's just as good as any of the Nikon TC's plus you'll keep auto focus. I have the TC14B and it's pretty good but in a comparison test I found the Kenko was a little sharper. It's not a good idea to stack TC's. The image quality will suffer considerably.
I never noticed vignetting with the Kenko Pro at any time when using it on a number of lenses. If it was bad I would have noticed. But I ran a test this morning using the AF 300mm f4 and the Kenko versus the Nikon TV14B.
First the Kenko and then the Nikon. I used my D3X with Vignetting Control turned off.
Is this what you saw. I can see the Kenko has a little vignetting and the TC14B does not. But I wouldn't call it terrible. In any case the Nikon TC looks more uniform across the frame.
I have a feeling the Nikon manual focus TC's aren't used so much any more. I use my Kenko Pro TC's for both my AF and MF lenses. However I do use the TC-16A with my D2X and MF lenses in order to get auto focus from time to time.
In my experience, the Nikon TC-14E II delivers slightly better results than the Kenko Pro 300 1.4x, but not be a huge margin.
If the requirement is for a TC to operate on a range of lenses, I'd opt for the Kenko; if it's for a TC to operate only on those longer "pro" Nikkors, then the Nikon would be my choice - unless I could afford both, of course...
Presumably, you have the current AF-S version of the 300mm f/4 Nikkor?
Bill (who posted the original question) has the earlier "screwdriver" AF version of the lens, which won't mount on the TC-14E II (or any current Nikon TC) unless modified - and even then won't autofocus.
I bought a 300 f/4 screwdrive AF lens a few months back. I have the 1.4x and 2.0x versions of the Kenko 300 DGX. I have not used the 300 f/4 that much yet (either alone, with the 1.4x, with the 2.0x, or with both the 1.4x and 2.0x), but in my limited testing the 1.4x is very good, the 2.0x is definitely useable, and the 1.4x + 2.0x combo is not very good. I do not have a good long lens support system, so I know the 1.4x+2.0x combo was affected by motion blur, adding to the poor image quality.
<< so I know the 1.4x+2.0x combo was affected by motion blur, adding to the poor image quality.>>
I wouldn't think that a x1.4 + x2 TC stacked together on an f4 lens is going to produce much of a useable image unless taken from a tripod, but even then it's pushing the limits. Stacking the two together will make a minimum aperture of f13.4!
I am sure either the x1.4 would be very useable giving a minimum aperture of f5.6, but a x2 giving minimum apertures of f8 may be less so, although in some circumstances acceptable. My AF-S 300mm f4 operates sweetly with a x1.4 Nikon and Kenco pro, slightly less so with a Nikon x1.7, but ok in good light. It was a non starter with my Nikon TC x2 II and I suspect will be so with the x2 Kenko.
Hello Bill, I just came across your post and I know you are talking about a TC 1.4. I have the Nikon TC 1.7E II. I rented a 300 F/4 AFS last week just to see how well the lens would perform. I was happy with my results so I think I will look for one. Here are a couple of shots that I took with It. Hope this helps.
Thank you Richard for your kind comment. This was my first time shooting with this long of a focal length as my longest lens is the Nikon 70-200mm f/2.8 which I think get good results from with the TC. Of coarse now I want the longer lens.
I get frustrated and to be honest after about 300mm or 630mm on a DX camera plus a 1.4 TC, the only answer is to get closer. Even my Sigma 50-500mm OS, being 750mm on my D7000 is often not close enough.
Wildlife photography could make me a very poor man if I succumbed to temptation to buy the long exotic wide aperture pro lenses
