On the recommendation of "Imagemeister" I purchased the Tamron SP AF 1.4x TC. I am very pleased with it. I have only used it on my Nikon 300 f4 lens. Make sure it is the "SP" model. They also make a cheaper 1.4x TC with fewer elements.

You may loose AF as this will push you to f9

So do you have to AF all the time or just when
it's lower light. I have this lens for Nikon and would
like to do that to

The Tamron, Sigma and Kenko 1.4X TC's will all mount on the Tamron 150-600mm lens, but the only one I can make retail full AF is the Kenko model. The Tamron and Sigma models retain partial AF in that the lens will AF, but it hunts quite a bit and will lock on while still out of focus regularly. Tested on T5i, 70D, 6D and 7D2.
All the above comments also hold true for the Nikon versions except that the Sigma retains full AF on the better Nikon bodies as well. Tested on D7100, D610, D750, D800E, D810 and D3S.

Thanks for this thread, was wondering the same thing myself. Shooter, is the 1.4 worth the loss in f-stop and any lost in quality or are you better off just cropping if you can't closer?

The loss of one stop is critical on an already slow lens like this. The tests I did were all done on a bright sunny day. On an overcast day, forget the TC. Overall, its pretty much a waste of time except for just the fun of playing with them. I actually stacked 3 TC's just to play with and the results were better than expected, but not good by anyones opinion.

Which Sigma model TC works well with the Nikon's?

There's only two I would buy, either the Tamron or the Canon. I have an older 2x Tamron from the dark ages. Don't think I've ever used it.

Save your money - your viewfinder will be too dark to focus manually, and at max zoom your camera will hunt and peck relentlessly for focus. If you care about image quality and want better results, get closer to your subjects. TCs are best used on fast telephoto primes and pro level zooms - usually F4 or F2.8. Results, at best will be only fair, and that will only be in excellent light and at an Fstop of F8 or F11.

Get a crop camera an a really good tripod you will be at 960mm with the tamron at 600. Most tc don't work well with other than the super teles .

I tried using TC's on zoom lenses, doesn't really work, especially something this slow already. Even on the Nikon 70/200 F28 I put the TC1.4 slight distortion and so forth. Keep the TC for a fast prime lens. I've learned to get closer to the subject.

With the already slow speed of this lens - yes, you will be better off cropping and proper resampling ( interpolation) enlargement. The better your sensor, the better this will work.
