Does anyone have the Tamron 150-600 G2 with Tamron 1.4 teleconverter and getting it to focus?

I have the 1st generation Tamron 150-600 and the Tamron 1.4 (and Kenko 1.4). I seem to recall that they focused using my Sony A99, but the results were not very good.

Lower light is tough and if you're trying to use anything other than spot focus that can add to it. You're shooting minimum F9 and do not have all focus points available.
Have you tried manual focus?

The 150-600mm G2 with the TC-1401 will AF pretty good on camera bodies capable of F8 AF, it will NOT AF so well on lesser bodies, or older bodies that do no accommodate F8 AF function. So the answer depends entirely upon what camera body you are using the combination on. The combo works extremely well on my D850, D500, and 5D MK IV bodies, but not well at all on my 7D MK II, D750 of Df bodies.

You need to specify your camera. Most cameras will have trouble focusing above f8. Some can only handle 5.6 reliably. Your telecoverter adds an f stop to your lens minimum so you are probably above that, at least at max zoom.

Have the same setup on a D7200 and yes, the AF can hunt, not even move, or get it wrong under lower light conditions. Most of the time I shoot in aperture priority mode and keep the lens wide open at 600mm and the AF gets close, then I use manual override to walk it in. I usually keep it on AF-C for birding with a single focus point, usually for a bird's eye. One sunny days, or light cloud cover, it works fine on its own.

If you are asking because you are thinking of getting one or both - without knowing what camera you are using it is impossible to tell. Some cameras can use a lens with a max aperture at F8 with one or more sensors. The Tamron would technically be F9, but it lies to the camera and the camera believes that it is an F8 lens.
A bigger problem than getting it to focus would be your support system. I think hand-holding is out of the question, and only a really solid, top end tripod and gimbal will keep the camera from vibrating and getting soft images.

I tried the Tamron 150-600 G2 on my Canon 7D Mk ll. In bright light it would focus occasionally. It would hunt allot and sometimes it wouldn’t do anything. It would focus using live view but I found it difficult to compose an image on the lcd screen in bright light and the live view focus was very slow. There was also some image degradation from the teleconverter and I felt that the Final image would be just as good if you cropped it using the bare lens. I also tried the Sigma 150-600 with their 1.4 teleconverter and got similar results.

If your camera has Live View, use that in manual focusing mode and zoom in on the screen to magnify the subject for focusing.

I have the 150-600 G2 and 2x tele for Nikon. Without the tele the autofocus works well, with the tele the scence needs to be very bright. I discovered this on forums before buying the lens. Even knowing that autofocusing would be an issue I got it anyway and I am happy with it. I don't mind manually focusing. Hopefully you won't be discouraged too much.
