"Lensrentals tested the new 24-70mm Sony GM lens and there are two good news:
World Class Optical Quality:
LR writes that it has “impressive MTF curves with excellent resolution“.
Compared with the Canon and Nikon 24-70mm lenses “the Sony is at least as
good as the other two lenses. It actually has the best center resolution,
particularly at higher frequencies, which backs up Sony’s statement that
this lens was designed with high-resolution sensors in mind.“
Low Copy-to-Copy Variation:
“To my surprise and pleasure, the variation of the Sony G Master lenses at
24mm is at least as low as, and perhaps a bit better than, the Canon and
Nikon zooms, both of which we consider good for zooms.“
Finally Sony is catching up (and maybe surpassing) with the big guys!"
