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
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 IITamron VC G2 vs. Sigma OS ArtTamron VC G2 vs. Tamron VCTamron VC G2 vs. Tokina
There are far more relevant comparisons to be made, but hopefully the above will get you started.
