As Tom said, the a99ii has IBIS. It is the most advanced DSLR on the planet with the least advanced good primes lol. Same with the a9. Most advanced sports camera on the market with no long primes for sports. Sony is confused lol.
Side note, I own the a9 and it's a perfect camera for me (I don't shoot sports) but I'm definitely not a Sony fan boy who thinks they do nothing wrong. I would have loved to have the a99ii, but Sony's last two good portrait primes were released in 2006. They haven't come out with an A mount lens in over 2 years.
