I'd been wanting to ditch my Canon gear and jump to Sony for a while, but the lens line-up lacked a good all-rounder. The 24-70mm was the lens that changed that for me.
Brilliant image quality, even wide open on the full-frame A7Rii, very sturdy with zero focal creep even if you're pointing the lens straight down (even then, there's a lock toggle for further stability), and very little noticeable distortion, even at wide angles -- this lens has lived up to all my wishes.
Comes with a good-quality carry case and a lens hood too.
My only gripe has been occasional AF hunting, but this will have as much to do with the camera as the lens itself.
Top, top lens -- at a price -- but worth the investment!
