Sony 135mm 1.8GM vs Sigma 135mm 1.8 ART | This may SURPRISE YOU!
https://www.dpreview.com/articles/1478096987/roger-cicala-tests-new-sony-fe-135mm-f1p8-gm-confirms-insanely-good-mtf-results
"The MTF drops away from the center, of course, but even at the very edges, the readings are still quite high.
Let’s compare it to the Sigma 135mm f1.8, which until today was the sharpest 135mm we had tested. In the outer 1/2 of the image they’re pretty even, but in the center half, the Sony GM is dramatically better, especially at higher resolutions."
Summary
"But as far as the test goes, the results are pretty simple. This is the sharpest lens we’ve tested. Period. (At last count, that’s out of 300+ lenses tested.)"
