i believe there is an a-mount sigma that does.
Tamron has a non-stabilized 70-200/2.8 for A mount, as well. Seems like the reviews for it were pretty good IIRC.
I am thinking about 70-400G2. I had been considering the Nikon 80-400, but I could use 300/4 + D600, and 70-400 + A7 and have a pretty sweet setup for wildlife/bird blind shooting. I always shoot from gimbal head or beanbag, so no worries about strain on the mount.
