I Recently started using the Tamron 70-200 G2 with my D750 and find the images are a little soft an all focal lengths (worse at 200mm). I have heard (rumor) that this lens was designed for a higher resolution camera such as the D810. Anyone with a similar experience? Should I have it calibrated or send to Tamron?

Check with Tamron. I have had two brand new ones (different final length) that I have had to send in to be recalibrated. Sharp after the recalibration.

Did you have to send in your camera also?

They did request basic camera info.

Since it was under warranty the recalibration was covered, just had to pay shipping.

hogilbert are you aware that Tamron recommends their optional TAP-in Console for fine-tuning select focusing adjustments and for updating lens firmware?

Basically all pro shooters who reviewed this lens mentioned that they only got stellar results after fine-tuning with the optional TAP-in Console... In fact Tamron actually states they would prefer you used the TAP-in Console rather than sending your lens back to them...

Now the not so good news... If you use the Tap-in Console then your lens is ONLY good for the particular camera you accomplished this on... Which is a MAJOR deal breaker for me since I have five different bodies I would like to use the lens on... Which isn't an issue for Nikkors since they can be fine-tune for each Nikon body I use... Thank you Nikon!

You pays your money and takes you choice... I hang in there with an all Nikkor kit on my FX bodies... only with DX do I use the Sigma 17-50mm f/2.8 OS and the 50-150mm f/2.8 OS which are light-years beyond anything Nikon offers for the DX mount in the way of Pro Glass... And both of these Sigmas can be easily fine-tune without using the Sigma dock console....

Hope this helps or is at least food for thought hogilbert

There's a good chance that it's back focusing or front focusing. I use the DataColor SpyderLensCal to check my cameras and lenses.

You can do the in-camera AF fine tuning or use Tamron's TAP-in console. If you send it to Tamron, they won't know anything about how your D750's AF is calibrated.

You have that a little wrong about the lens being for higher resolution cameras. What they mean is that it has sufficient resolving power to be used on higher resolution cameras. It's fine for your D750.

It is not the resolution of the camera that is causing the softness. More megapixels on the sensor will be more megapixels of softness.

Some questions. Tripod or hand held? What shutter speed are you using?

Also are you shooting wide open or stopped down? Some lenses are soft wide open but acceptably sharp stopped down a bit.

Have tried manual focus, on a tripod, to eliminate lens-camera focus calibration mismatch?

If all else fails, take the lens back to the store and talk to them about the problem. Ask to try a few others pick one that is sharp.

The (rumor) is false. And that rumor centers on the D850. The truth is the D850 makes all lenses used on it BETTER.
And the fact is this, Tamron lenses are designed to work on several camera's, Nikon lenses, on the other hand, are specifically designed to work on ONLY Nikon camera's. I could go into a very long discussion about third party glass, but I will not.
Let me just say that the Nikon 70-200 VRII and it's successor do a fine job and deliver outstanding results time and time again.

Tap-in console (Tamron) would be a good addition, and I imagine you can also tweek sharpness on the 750, and use lens fine tune capability if it has that (check your shooting menu).

I have to say I am not a fan of Tamron lenses in general. Like billnikon, I prefer Nikon lenses and none is better than the newest 70-200/2.8E FL. Such a sweet lens! I do also like the Sigma ART series. My comments are based on my personal experience. Best of luck.
