Hi all,
I have a 70-200 2.8 that I use for sports (indoor hockey and evening sports). Paired to a D500.

I want to start to do some birding and also looking for little extra reach when doing sports (in good light).
My question: Will the 1.4 or 2.0 give me good results? How much will the focus slow down?

Do I just save for a Nikon 200-500, 5.6?

Thanks

On a D500, you have a FOV of 105-300mm. You may want to see which teleconverter is proper for a Tamron lens on a Nikon camera. I personally would only use a 1.4X teleconverter
If you need more reach for sports, you may want to look at a Sigma sports lens in 150-600mm. I always thought that a Nikon 200-500mm on a D500, was more of a Wildlife Lens, rather than a sports lens?

The Tamron 2X TC would give you a 140-400mm F5.6 lens, and it wouldn't be "bad" really, but it would be nowhere as good as the 200-500mm Nikon nor the 150-600mm Tamron on your camera.

For sports, Maximize your IQ with a 1.4X and CROP - use well applied pixel enlargement software for larger prints. For birding, TRY the 2X - maybe rent to see if it meets your requirements.

I had that lens and loved it for sports. It zoomed and focused too slowly for a college women's softball game so I sold it and bought the canon 70-200 2.8. I fell in love with its fast focussing.
I generally leave the 1.4 on the lens for sports. The 2.0 cuts too much light for my use, but use it when my wife and I go to the zoo. It does not give nearly enough reach (equivalent of a 400) for birding. Also. it seems that the 2.0 shoots a bit soft at times.

Jim,
What lens did you sell that you did not like?

Do NOT get the 2x converter.

Why?

my Niko 1.4 tele will not mount on my Tamron 70-200. The tamron has a small protruding bit that prevents the mounting. If I am doing something wrong, let me know.

From everything I looked at on-line it makes it a slow 5.6. I'm still looking for some focus speed.
A few other issues, but that was the main one I was concerned with.

Very soft with 2x converter and you lose 2 stops of aperture. If shooting sports, either indoors or in low light, this becomes a factor.
Better with 1.4 and crop.

The aperture loss is of course obvious going into it. Softness is not so obvious and would certainly be an issue. You are talking of the Tamron 2x TC with the Tamron 70-200/2.8 specifically since results depend on the details of the combination?

I expected the Tamron 2x TC to work well with their 70-200/2.8 with some, but not large, image and/or AF degradation. The Nikon equivalent combo seems to do pretty well.

Yes, I would expect the Tamron 70-200 with THEIR 2X to do very well ! I would expect that the TC and lens to be optically optimized - unlike the Canon or Nikon 2X's which are optimized for 300mm f2.8 PRIME lenses ! - since Tamron does NOT make a prime lens and would not make complete sense to optimize it for the 150-600.

Correct, Tamron Lens with Tamron 2x TC.
I was very disappointed.
