Tamron 150-600 G2 (Page 3): Thank you, V2. I think I will contact Tamron to see what they have to say.

I also have the G2 version of this lens and use it on my D750. In case others haven’t mentioned Tamron has a TAP in console to upgrade the firmware if it needs it and another way to fine tune the lens to your camera. I am not sure if this is even better than the 850’s auto fine tune. You can send to Tamron from what I understand if you don’t want to do this. Others may have additional info.

Thank you, V2. I think I will contact Tamron to see what they have to say.

I use this lens on a regular basis, have never had a focusing issue. Good luck to you.

Thank you. I appreciate your response.

Have you tried using the Tamron tap in console? Not sure they always do a good job but it might be worth giving it a try. I used it on my Tamron 18-400 and seemed to help. But I only have one camera body so not concerned with switching! :)

I didn't get the console with the lens. I think it's about $60. Do you think it's worth it? I've heard it's a pretty involved process. Plus there is a reluctance on my part to spend time and money fixing something that shouldn't need fixing IMHO.

I'd check various reviews. Here is just one that mentions the lens you're working with:

Also, if you haven't already, check out Steve Perry's info for fine tuning in general.

For me, the tap in console gives you more options to correct back/front focus issues at the various focal lengths.
Good Luck!

Here is a thought. I have my G2 on my old T2i. I have time on my hands so I might try comparing the AF using it, then my 80D. If they both are off the same, it is probably the lens, if different, the bodies contribute to the error.

I have this lens 150-600mm G2 and quite happy with it. If you want to calibrate the lens so it works with number of cameras you may try to calibrate it wit the Tamron TAP in console which calibrate the lens itself(I did read on this site about a year ago that some copies of these lenses has focusing issues)
I went through this process of using the TAP in console and had to adjust the lens in the 600mm only.
Now, I am not sure if this type of lens calibration would fit different cameras. I will have to try it on my Nikon D700 as I tried it on my Nikon D800E and it sharp!!!

Two comments: the previous owner may have made an adjustment with the Tapin console. You may need to reset it. I have an older Nikkor 300mm F4 that I adjusted with my D850s focus adjustment. I works great until I change lenses and forget to turn it off. I prefer the lens adjustment of the tamron. Good luck.

I bought the 150-600 G2 from B&H early last year and had only one camera at the time (an a77). I found that I needed to do the fine tuning - first time doing it - and now shoots spot on. It works nice as is on my a99ii. Cameras remember 20 or 30 lenses so if you need to fine-tune it once it will remember the setting next time you use it. I have a few other lenses, some that might need adjusting on a particular camera and some not...I think my 105 macro is perfect on the a77, but not quite right on the a99ii. Lenses and camera are each made to a certain spec in different factories. There's always a chance that the optics might not match up. That's why cameras have the option to deal with front or back focus. Last summer at Oshkosh I got a picture-hanger that was chosen as Picture of the Week in an online aviation newsletter using the 150-600G2. A focusing target, a footed monopod, filters and a few other things (even software) came with the package deal!!

That sounds logical. Thank you.

Yep, I thought of that too. Thanks.

My lens seems to play well with the D500. I'll try it with my other D850 and see how that goes. Thanks.
