First (and Second) Looks at Tamron 24-70mm f/2.8 Di VC USD G2 Lens Image Quality

Along with the formerly shared vignetting, flare and distortion test results along with specs and measurements, image quality test results from two different lenses (one tested on three cameras) have been added to the Tamron 24-70mm f/2.8 Di VC USD G2 Lens page.

I recently posted about not being satisfied with the results from the first lens we tested and I took those results down soon after assessing them. We have now tested a second lens (one with a notably-higher serial number) and, though the second lens (sample "1") performs modestly better, I think that you will find the two performing rather similarly overall. As the odds of getting two bad lenses with substantially different serial numbers that perform similarly are very low, I am going to share the results with you, at least until I'm convinced that they are not right.

More convincing is looking at this lens in comparisons where it competes reasonably well (perhaps the only issue was that my expectations were set too high). Here are some comparisons:

Tamron VC G2 vs. Canon L II
Tamron VC G2 vs. Sigma OS Art
Tamron VC G2 vs. Tamron VC
Tamron VC G2 vs. Tokina

There are far more relevant comparisons to be made, but hopefully the above will get you started.

The Tamron 24-70mm f/2.8 Di VC USD G2 Lens is in stock at B&H | Amazon | Adorama | WEX (preorder).

Deal of interest: B&H has a used Canon EF 24-70mm f/2.8L II USM Lens in 9+ condition for $1,519.95.
